N June 1908 the Governor-General of the Province of Mozambique did me the honour to invite me to join a Scientific
Expedition which was then being sent by Government to inspect portions of the Province, with a view to assisting the development of such resources of these localities as are more or less allied to agriculture. Previous familiarity with the forests of other parts of South Africa, and their constitution, rendered such an opportunity to supplement that by a personal knowledge of the more tropical forests along the east coast desirable, so I accepted with pleasure, and spent several months during the winter visiting the various districts of the Province, in so far as time would allow, and making the forests, the botany, the arboriculture and the horticulture special objects of study. The result, in so far as the forests and forest flora are concerned, is embodied in the present work, which, beyond my own observations, records previous collections to the extent of allowing it to be a handbook of the forest flora based on available data, and indicative of the vast forest wealth of the district. It naturally takes at least a whole year's study of every portion of a country to supply the data necessary for a full and complete work of this nature, but that being impracticable in the present instance, a winter's tour has had to do instead, during which the trees were mostly in fruit but few of them in flower, and the few deciduous species were more or less leafless ; it would be surprising therefore if omissions have not occurred, or if the information is not in some cases incomplete, but since the predominant and most important kinds have yielded material sufficient for identification, I feel satisfied that the production of this work, in its present form, serves the purpose intended by Government toward fostering the economic development of the Province, and especially of the districts visited, by aiding identification, by indicating qualities and uses, by reducing the vernacular nomenclature into intelligible order, and by showing in what localities and in what species value lies, and the possible means of converting that potential value into hard cash.
In accordance with a desire expressed, that readers should not be diverted from the main features for identification by the interpolation of full scientific descriptions of organs less essential for that purpose, the descriptions have been purposely made short and pointed, full botanical descriptions being in most cases redundant in view of their having already appeared in the Flora of Tropical Africa," where however the local and economic aspects of my present subject are absent. For synonymy readers are also referred to the same work, which is an invaluable aid to every student of African botany, and in which the following collections from Portuguese East Africa have been dealt with, viz. :-From the Zambesi, Shire, Rovuma and Lake Nyasa, the collections made by Sir John Kirk, Dr. J. Meller, Dr. Peters and Mr. Horace Waller, have been used in all the volumes; while in all, except the first three volumes, there have also been used collections, mostly from Nyasa-land, made by Sir H. H. Johnston, K.C.B. ; Rev. W. P. Johnston, Mr. J. Buchanan, C.M.G.; and Messrs. K. J.
Cameron, J. T. Last, J. McClounie, L. Scott and Joseph Thompson.
I hardly require to repeat the warning given in so many forest works that venacular names alone cannot be relied upon for identification, but they are useful aids if taken along with the botanical description. In the districts visited I found the vernacular names surprisingly constant within a tribe, and every man, woman and child knew that name ; indeed the exact knowledge of the trees and the nature of their music were the two outstanding and surprising features in the sometimes very low type of humanity.

vi Preface.
The reduction of the vernacular names into order has been a most difficult task, since the stem in most names is preceded by one of many prefixes which are used alternatively in accordance with grammar, usage or individual choice, while most of these prefixes begin with indistinct sounds not reducible to English letters, and often not fully pronounced, or lisped more or less from one sound into another ; in such circumstances indexing is very unsatisfactory, either by the prefix or by the stem. The exigencies of Portuguese politics, and the necessity to publish while funds are available, has rendered impossible the collation of specimens with other herbaria than my own, or even with works of reference not immediately at hand ; the specimens and information collected had, therefore, either to be dealt with at once or probably never, and I preferred the former, even though in some cases-such as Ficus and Acacia, it involved describing under a new name species which may possibly have been described before.
My aim has been to allow each of the trees yielding important economic products to be easily identified under some name,-which previously was not the case, through the publication of many names in scattered scientific pamphlets-the reduction of these, where necessary, to the first published name must wait the opportunities of those who have time and data in unlimited quantities.
Meantime the Province must be developed, and a saleable article must have some recognised name. The value of the timber in the Province is enormous, but that material will be gradually burned out to make way for cultivation unless utilized first.
My thanks are due to the Officers of the Government of the Province of Mozambique for kind assistance on every hand, but more particularly to His Excellency the Governor-General Major Frere d' Andrade, Dr. Saldanha and Dr. Sousa Ribeira, who were the prime movers in regard to the Expedition ; to 0. W. Barrett, Esq., Director of Agriculture, who has rendered much valuable assistance ; and to Administratadors Milicia and Alves, who, with extensive personal knowledge of the local products, did everything in their power to assist me. Also to James W. H. Trail, Esq., M.A., M.D., F.R.S., Professor of Botany, University of Aberdeen, whose co-operation has been invaluable, and to Messrs. Taylor & Henderson, The King's Printers, Aberdeen, who, at a distance of many thousand miles from the Author, have placed this work before the public in what I feel sure will be considered excellent form, in so far as they are concerned, within a few months of the completion of the journey which led to its production.

Forest Flora and Forest Resources

Portuguese East Africa.
1 ORTUGUESE EAST AFRICA constitutes what is officially known as the Province of Mozambique, and extends along the Indian Ocean from 10 S. to 270 S., being ~ bounded by Natal on the south, Swaziland, Transvaal, Rhodesia and British Central Africa on the west, and German East Africa on the north. The outline is very irregular, the north-eastern portion being about 40'50 E., the south-western 320 E., while an irregular arm extends up the Zambesi as far as Zumbo, 30 E. It thus contains approximately 76o,571 square kilometers (= 3oo,ooo sq. miles), and has a population estimated at 2,650,000.
History. What its ancient history may have been hardly affects our subject, but its more recent history begins with the discovery on its coast in 1498 by Vasco de Gama of several bays and estuaries suitable for commerce, since which date the seaboard has remained under the Portuguese flag. Occupation by the Portuguese of various ports began soon after the above date, and such towns as Mozambique, Quelimane and Inhambane have been in existence for about 400 years. The hold upon the back country, however, was for long of a very nominal nature, and it is only within recent decades and since the adjustment of the borders, that military occupation of the outlying districts has been seriously taken in hand ; indeed there are places still which can hardly be said to be officially occupied, and which are almost unexplored.
Occupation. Official occupation usually begins with the residence of a military Commandant, who exercises powers somewhat similar to those conferred under martial law in British colonies, and is supported by a military force composed almost entirely of natives ; this is superseded as soon as practicable by civil administration under the laws of the Province, the Resident then being Administratador, and supported by only a small police force. In each case the duties of keeping the peace and collecting taxes (hut-tax in sonic places, poll-tax in others) falls upon the officer in charge, who also has to have such roads cut through his district as are necessary for these purposes.
Population. Apart from the few towns and villages, the population is almost entirely native, and except the southern districts the country can hardly be regarded meantime as a white man's country, though the control of all industrial, as well as official, work and also the management of machinery, &c. is, and probably always will be, in European hands, the manual labour devolving upon the native.
In some large districts meantime the few officials form the entire non-native population ; in two districts visited by me the Administratador and his clerk were the only such, except a few Indian traders known as Banyans. The natives are of many tribes, mostly of Bantu origin, but differing in their customs and instincts and speaking different languages, there being about ten distinct native languages used in the Province, besides dialects ; these, together with Portuguese (the official language), English, Dutch, German, Spanish, French, and various Indian and Arab languages, constitute a fair babel, out of which I have had to cull the information contained in this work, in so far as it is not supplied by the trees themselves.
Physical Features. In physical features the Province may be described as a nearly level more or less sandy plain, with isolated kopjes in the north, and rising rather abruptly to a low mountain range on its western boundary, and crossed by numerous rivers, several of which are navigable for many miles, while others, navigable inland, are closed from the sea by a sand bar. The soil in such river valleys as those of the Limpopo and the Zambesi is of the richest alluvial; elsewhere the soil is more or less sandy loam, except on the western hills which are of igneous rock, often fully exposed, and seldom covered with sufficient soil to support full vegetation. The underlying strata from Beira northward are composed of rocks corelated with the Swaziland system of the Transvaal and with the gold-bearing strata of Rhodesia. These rocks probably roughly correspond in age with the pre-cambrian rocks of England. South of Beira the underlying strata consist largely of rocks belonging either to the tertiary or cretaceous systems, in places beds of conglomerate being present and are fringed along the western border by rhyolites. In the north this is divided from the Archaean rocks by a band of igneous rocks, made up of porphory, &c. In popular language the soil may be described as mud on the flats, sand elsewhere, and solid rock on the hills; surface rocks or stones are entirely absent on the flats, while toward the coast lakes and lagoons exist in some places, and considerable areas are more or less under water during summer, which, for cultural purposes, might be rendered fit by deep surface drainage.
Vegetation. The vegetation varies with the district, but in a general way it is an open thorn-veld in the southern districts, a light bush-veld from the Limpopo northward, and a dense and sometimes heavy forest north of the Zambesi. Grass-veld occupies the open valleys, and in the more open thorn and bush-veld grass is abundant as undergrowth, the annual grass fires doing an immense amount of injury to trees ; only those of the thorn group (Acacias, &c.) endure such repeated scorching and consequently continue to exist where other kinds are killed out.

2 Forest Flora of Portuguese East Africa.
Native cultivation. The natives usually do enough cultivation to supply their own wants, and in some places grow ground-nuts, mealies, sesame, &c. for export, but the money brought into the Province during recent years from the Transvaal by natives who have gone there to work, has rendered the native population less dependent on its own agricultural industry, and consequently less inclined to grow crops beyond what are required to meet its own immediate wants. With the improvident and thriftless habits of the natives local famines are not uncommon, and are often preceded by the undue consumption of edible products in the form of fermented or distilled liquors. The export of native products has decreased very considerably during recent years, mostly through the export of labour which has not been an unmixed blessing.
Stock and Transport. From various causes, mostly preventable, including rinderpest, fly-borne diseases, and the high prices consequent on these, cattle are scarce everywhere, and through large districts entirely absent; horses are subject to horse-sickness unless stabled at night and otherwise cared for, mules are not immune from the same trouble, and donkeys are too light for the mud and sand, so transport is meantime difficult and expensive, native carriers being in all remote districts the only power available. There are, however, several railway systems, viz. :(i) Caminho Ferro, Lourenzo Marques, crossing the Province from Lourenzo Marques to the Transvaal border where it joins the Central South African Railway and
so connects the Portuguese port with Pretoria, Johannesburg, Barberton, Komati, and the rest of South Africa.
(2) The Swaziland line from Lourenzo Marques, intended eventually to be carried through Swaziland and to form the shortest route to Johannesburg. A small branch
from this line has its terminus at the Umbalusi experiment farm.
(3) The Rhodesian railway crossing the Province from Beira to Rhodesia, connecting with the railways from Cape Colony at Bulawayo, whence extends the line
crossing the Victoria Falls, and which may eventually have termini at Lobito Bay and Cairo.
(4) Narrow-gauge railway from Quelimane northward for about 20 miles to Maqueval, bringing the Macuse and other rivers into touch with Quelimane.
There is also regular steamship communication by large vessels from and to Europe, and calling at all Cape ports, between Lourenzo Marques, Inhambane, Beira, Quelimane and Mozambique, while smaller steamers up to i5oo tons make a regular coastal service along the Province and visiting the above-named ports together with Chaichai, Bazaruto, Bartholomew I)ias, Chinde, Tjungo (Bajon), Angoche and Porto Amelia, and there is occasional service up the Zambesi, as well as to Marracuene and Bella-vista, and up the Maputa River, and elsewhere as required. The harbours are in most cases good; the entrance is in some cases difficult owing to sand-bars. Communication by sea is thus as good in the Province of Mozambique as it is in Portugal, or in England, but the frequency of the voyages depends to some extent on contracts and on the trade of the ports visited.
Beyond the ports mentioned navigation is carried on by boats and barges for a long distance up several of the rivers, as well as up rivers not open to the sea, while even the small streams, so long as they are not too rapid, are used by native dug-out boats, for the transport of produce and passengers.
Apart from the district of Lourenzo Marques there are few wagons, trollies, carts or carriages in the Province ; Lourenzo Marques has a good electric tram service ; the other towns have tram service by native power ; mules and donkeys are the means of getting about where these exist and are fit for the roads ; and, where these are unfit, the Mashila, viz. a hammock slung on a bamboo and carried on the shoulders of four natives is used. This latter contrivance is the only means of passenger transport in Zambesia and northward, and as the bearers keep up a kind of trot 30 to 35 miles a day can be covered, two or three relays of natives taking turn at carrying, but all keeping in company to do so as required.
The native baggage carriers or croquedorras also do a similar distance, carrying from 6o to ioo lbs. each, and walk or trot at a pace exceeding that which a white man can keep up, and they can do so day after day for a week or two, living only on manioc (cassiva) obtained as they go along.
By the above various means most parts of the Province can be travelled without difficulty, but the cost of transport of produce is still the main impediment to the rapid development of many districts, especially where outlying places arc concerned, and several development lines are meantime under consideration, one of which, from Chai-chai to Inhambane, would be of immense value, going through a most productive country, and would also connect the Inharreme river, making it a serviceable water-way for some fifty miles in another direction.
Agriculture cannot be said to have made much progress until within the past decade or two, and even now there is room for improvement. In the neighbourhood of Lourenzo Marques one would have expected the near proximity of the Transvaal markets to have encouraged the culture of tender fruits, winter vegetables and flowers, and the various other products which can be grown on the coast but cannot be grown inland, at least at the same season. But with the exception of Dr. Saldanha's fine farm at the Umbalusi it may be said that nothing of this kind is done, indeed the local market is badly supplied and often has to draw its supplies of produce from Natal or the Transvaal, which could easily be produced locally. It is also exceedingly surprising that the grand alluvial valley of the Limpopo should have remained so long undeveloped, suited as it is for the production of sugar, lucern, grain, &e., as also the ranching and agricultural lands on the Incomati and upper Limpopo.

General Description of the Province. 3
In the neighbourhood of Inhambane sugar and cocoa-nut production are making good progress, a factory is at work making cassiva flour, and ceara cultivation has been attempted, but the export of oil-nuts and grain has been falling off, mostly through the prosperity of the natives in other directions.
Thence northward, a huge tract of country 60,o00oo square miles in extent is in the hands of the Mozambique Company, administered under a Royal Charter granted by His Majesty the King of Portugal in the year i89r. This is said to be the only Chartered Company now extant governing territory which had been under the direct administration of a European Power previous to its charter being granted. The Territories of Manica and Sofala are its area; the city of Beira is its capital and port; both administration and development are being actively carried on ; and in addition to its own efforts it has several subsidiary companies at work, mostly on British capital, producing sugar, sisal fibre, rubber, &c.
In the Districts of Quelimane, Tete and Mozambique the Government retains the administration and has immense areas still in its own hands, but there are also various companies doing most valuable development work in a most thorough manner. According to the "Annuario de Mozambique," 1908, the position of these for 1907 is stated as follows :(i) Companhia de Zambesia, capital 2,025,000ooo000 reis (=400,00oo), with prazos (estates) as follows :-Magenja-alem-Chire, with 2oo00 hectares virigated, to be increased
to 2000; Massingire, with 72,140 coffee trees, 330,000 sisal plants, 3400 cocoa-nut trees, 2oo000 acres of planted rubber, including large trees of castilloa and hevea;
Andone Anguaze, with 149,oo000 bearing cocoa-nut palms, and 225,000 cocoa-nut plants in nursery; and Timbud, for the exploitation of timber only.
(2) Companhia de Boror, capital 54o,o0000oooo reis (= i io,ooo), with prazos at Boror, Tirre, Lycungo, Macusse and Nameduro, containing 401,200 cocoa-nuts in bearing,
250,000 ditto in nursery, 240,000 coffee trees, 350,000 rubber trees, 250,000 sisal plants, i6 hectares cotton and 350 hectares sugar.
(3) Companhia de Luabo, capital 990,000ooo>000ooo reis (=,200,000), with prazos at Luabo and Marral, containing 66,ooo cocoa-nut trees in bearing, 30,000ooo ditto in nursery,
So,coo rubber trees (Castilloa and Ceara), 66o,ooo sisal, 90 hectares cotton, and 1290 hectares sugar grown by the subsidiary Marromeu Company.
(4) Society du Madal, capital 785,oo0ooo reis (= i5o,ooo), with prazos at Madal, Tangalane-Cheringone, and Mahindo, containing 124,970 cocoa-nut trees, and
100,000 in nursery.
(5) Companhia do Assucar de Mozambique, capital 1,35o,ooo000'ooo reis (= 270,00oo0), with prazo at Magenja-aquem-Chire, has 1550 hectares sugar and produced 500ooo
tons sugar last year.
(6) Gavicho de Lacerda, at Carungo has 54,o000oo cocoa-nut palms, and 30,000ooo ditto in nursery.
(7) Soutulho Rodrigues, at Inhassunge has ii,6oo cocoa-nut palms, and 7000 ditto in nursery.
(8) Mariano Nazareth, at Pepino and Quelimane do Sal has 37,000 cocoa-nut palms, and 20,000 in nursery.
(9) Empresa Agricola do Lugella, capital 37,ooo0sooo reis (= 7500), with prazos at Lugella, Lomue, and Milange, has large nurseries of cocoa-nuts.
(io) Messrs. Helliard & Hamburger, at Nhamacurra, produce iooo tons of sugar per annum.
The northern part of the Province, extending from the Indian Ocean to Lake Nyassa, and separated from German East Africa by the Rovuma River, is another huge tract of country in the hands of the Nyassa Company, from which mangrove bark has been exported in some quantity, and in which a railway is projected for 250 miles westward from Port Amelia.
Agricultural encouragement. During 1908, and largely owing to the agricultural activity of Dr. Saldanha and the encouragement of Governor-General
Major Frere d' Andrade, the Government organised an Agricultural Department, under a Director of Agriculture, assisted by a Veterinary Surgeon, an Entomologist, and a small office staff. Restrictions on the movement of cattle, rendered necessary by East Coast Fever, Plant import regulations, the distribution of seeds of high quality, grains, &c., and various other measures, have resulted, and the Department has in hand the arrangement and equipment of an experiment farm at Umbelusi which will probably do more to wake up the Province as to its agricultural potentialities than any other means yet tried. The scientific mission, of which this volume is one result, and in which the various members of the Departmental staff, and others, took part, was one of the first acts of the Department, which, if regularly supported by sufficient funds, will revolutionise the Agriculture of the Province, render the Province self-supplying in practically every article of domestic consumption-as it easily can be-and also bring in a huge revenue from the export of agricultural and forestal products. Meantime that export is very small. In the Mozambique Budget for the year ending June 3oth, 1909, the principal items of revenue estimated are hut-tax 272,000, customs 224,oo000, railways 250,000, and native emigration 57,000 ; while among the items of expenditure are the military service 2 14,oo000, railways and harbour 146,oo000, colonial expenditure in Lisbon 17,200, passages of officials to and from the Province /26,oo000, Agricultural Department /8200, experimental farms 5200, fencing and stock /6ooo, Catembe graving dock 8000ooo, dredging Polana and the wharf wall 40,000, and railway rolling stock 1 7,oo000. These figures speak for themselves as to the position of internal development in the Province.

The Forests.
HE forests of the Province of Mozambique are bounded only by the boundaries of the Province itself, that is to say, the whole Province is one forest, except in so far as
fire and the axe have interfered with it. But its value as forest varies immensely, and it will be necessary to consider the localities separately.
(I) The District of Lourenzo Marques, including the circumscriptions of Maputo, Marracuene, Sabie, Manhica, and Magude, together with the upper portion of Gaza (Guija).Throughout the whole of this area thorn-veld prevails, composed in great part of Leguminous trees scattered far enough apart to allow an abundance of grass to grow underneath and still close enough to maintain an open canopy throughout. The trees are usually of no great height, 30 to 5o feet being the average except along the streams, while in diameter io to 15 inches is the average. As the grass is burned every year, clean unbranched stems prevail, usually straight and without taper for io to 15 feet, but seldom available for technical purposes in 20 feet lengths, and usually with a rounded or more or less bushy crown. Many of these trees are of extreme hardness, and have black or red heartwood; so far as a local demand exists for hardwood, it is easily met with good material of good kinds. A considerable industry formerly existed along the main line of railway in sending poles of several species of Acacia, under the name _A/kai, to Johannesburg, for use in the mines, where the strength and durability gave this a special value ; but the available material within easy distance of the railway has been practically worked out, and now that the Swaziland railway brings other areas within reach, the Government has prohibited the felling of this timber until such time as arrangements are completed for felling on license. Of course here as elsewhere many trees of larger size occur, mixed among these hardwoods, but usually they are exceedingly soft, such as Ficus or Commiphora, and withstand the fire through their sappy nature, but are of low technical value. The number of species of timber trees is very large, the Acacias are more or less gregarious, but other kinds occur in very scattered fashion, and of several species I only saw single specimens. The largest trees are either too soft or too hard to be worth working under present conditions, and no timber industry exists on the flats though valuable timber is there in abundance. In Lourenzo Marques only one
wagon-maker is at work, mostly on repairs, and his demand for local timber is very limited.
The species composing this thorn-veld are mostly different from those which occur in Natal and Zululand, the line of division being where the sandy flats
begin, north of the Umfolozi.
On the Swazi border where an altitude of 2000 feet is reached the tree-flora is very different. Trees are not abundant or large except in the Kloofs, Acacia is
less abundant, Combretum more abundant, and many trees of the Kaffrarian and Natal forests appear, such as Podocarpus, Toddalia, Olea, Ptero-celastrus, &c.
Cussonia, which is absent below, is still scarce, and a Ficus takes its place as the last survivor on dry rock. Curiously enough, I found dense gregarious thickets, including very large trees, of a species (Weihea ? subpeltata) which otherwise I only had from near Mozambique. On the top of the I.ebombo range, at Estatuene, a Dutch wagon-maker, Mr. H. Du-pont, carries on an extensive business, doing most of the wagon work for Swaziland, aU with local material, of which he held a considerable stock, well seasoned, and I considered the information received from him, supported as it was by wagons, timber, furniture and building material in his
possession, to be most valuable, and most of it was corroborated by Mr. Stem, of Swaziland, who happened to be living below the Lebombo when I was there.
On the Transvaal border most of the kinds are common to Gaza and to the Eastern Transvaal. Near the coast a belt of litoral kinds on the dunes and sandy plains corresponds very closely with the flora of similar positions in Natal, while on the muddy shore the more or less cosmopolitan mangroves of similar latitudes abound. Trichilia and Anacardium are common on the sandy flats, as also are two species of
Strychnos and one of Garcinia, together with the rubber-yielding Landolphia, Kirkii, and latex-yielding Ficus species.
Several floras thus meet within the district, which consequently has a very large number of ligneous species, and a large number of kinds yielding valuable
timber, but seldom dense forest or large quantity of one kind, except the Acacias.
(2) The lower portion of Gaza and the district of Inhambane.-History has left its mark here. Closely inhabited by a most industrious agricultural population, who know the value of fresh forest areas for agricultural work, little of the original forest now remains, and present or past cultivation shows everywhere. Large as must be the area which has been cultivated and then abandoned in the ordinary course, there is probably a larger area which relapsed about twelve years ago during and after Gungunhama's raid. Fortunately the bush reasserts itself if given an opportunity, and that abandoned during the raid is now a thriving young dense forest, 12 to 20 feet high and with stems six to nine inches diameter. Most of the area under consideration may be described as a Tzontzo forest (Brachystegia), this tree being the predominant

species in regeneration and probably much more abundant now than before cultivation began. But unlike the majority of assertive weeds, this tree as it increases in quantity increases the value of the forest, alike from the native's point of view and from that of the European utilitarian. This tree is absent from the Lourenzo Marques forests, and is only one factor in a crowd in the Quelimane forests, but in Gaza and M'Chopes there are large areas where there is nothing else, where cultivation has
been practised at some former time.
But the native, in clearing for cultivation gives this no quarter. It is true that he acts on a list of reserved. trees-reserved by native traditional practice, and
likely always to remain so-but the native's choice is exceedingly practical ; if a tree does not yield food or drink it has to go. Trichilia (Mafurreira) and Anacardiurn (Cashew) arc reserved everywhere, Mango and Orange where they occur, several creepers under the names n-kaloga, tinta, shangala, &c. from whose fruits wine is made are allowed to form suberect bushes in the cultivated fields, and pine-apple borders every field-reserved for the sake of the spirit distilled from its fruit rather than for the fruit itself. A Ficus is also reserved, or even cultivated, for the cloth made from its bark, but a timber tree is hardly required in the domestic economy of the native, and consequently is cleared as a weed. Even such a useful tree to him as the Brachystegia is cleared without hesitation, since the uncultivated areas contain it in
The general character of the aboriginal forest in this locality is of a dense evergreen nature, rather undergrown as might be expected from the light sandy soil
on which it has to develop, but containing many valuable species not frequent elsewhere. In a few spots, especially coastward, one might have been tempted by the vegetation to believe he was in Natal, Natal species forming the jungle almost to the exclusion of more tropical kinds, but the bare sandy soil, the absence of ferns, lickens or mosses, and the intrusion of Brachystegia and Dracaena were distinctly non-Natalian. In the neighbourhood of certain lakes in Manjacaze and Zavalla, on sour and rather wet sand, Eugenia cordata was the only tree, and an Erica the only shrub. As Inhambane is approached the Baobab (first seen at Inharreme), makes a frequent appearance, and near the rivers cocoa-nut palms become abundant in cultivation, along with fine specimens of the Tamarind and other exotic leguminous trees,
and the Jujube, which, however, was not noticed wild here. Inhambane coffee is a natural product of the forest, and makes an early regrowth after fire.
On the tidal mud cf the estuaries extra-tropical mangroves are abundant, but being mostly Avicennia are of little value. Landolphia Kirkii is abundant in
many parts of the district, and the Banyan traders do a considerable business in buying its rubber from the natives ; rubber or gutta is probably also obtainable from the various other Apocynaccous trees, shrubs and creepers present, as also from a species of Mimusops ; the scented timber of Excaecaria may also form an article of commerce, and the seeds of Trichilia do so at present, for the oil obtained therefrom. An Euphorbiaceous tree seen only along the Inharreme River gave an enormous flow of thin latex, which may be found of value. This district, despite the enormous extent of present and past cultivation, holds a high value of forest products, and only
requires a railway to make these available.
(3) Manica and Sofala, being administered by the Companhia de Mozambique, did not fall within the scope of my investigations, and I only saw the bush immediately surrounding the three ports, Bazaruto Island, Barthelomew Dias, and Beira. I had, however, the good fortune to meet Mr. W. H. Johnson, F.L.S., Director of Agriculture to the Companhia, and who has also the forestry in charge, from whom I learned that except what has been taken up for cultivation, the whole territory is practically open forest, though in many favourable localities it becomes more or less dense. The species present are perhaps in accordance with the soil and rock formation, and also the climate more or less identical with those of Inhambane as far north as Beiia, whence they correspond more with those found on the Zambesi and northward. In the forests the Company is mainly interested in the collection of rubber, of which over 8oo tons have been exported during the past 14 years, some of the forests being worked by private enterprise, and some by the Company itself. The rubber is mostly the product of Landolphia Kirkii, but Landolphia Buchanani, Landolphia florida and Mascarenhasia elastica probably also yield a quota, while Diplorhynchus mossambicensis and a Ficus are also latex-yielders. Dalbergia melanoxylon is said to be one of the best timbers, but was not seen by me. As seen from on board ship the whole coast is composed of sandy dunes, on which Casuarina is the prominent and often the only tree, standing erect and tall even when solitary in the most exposed situations, and making more or less open bush where gregarious. In the estuaries
mangroves abound, including the more tropical kinds, but the industry in mangrove bark is limited, mostly through the scarcity of the better kinds.
Diospyros, Sophora, Suriana, Elaeodendron, &c., constitutes a very distinct litoral bush flora behind the mangroves at Bartholemew Dias, which was not seen
(4) Quelimane, and northward and westward.-Although the immediate neighbourhood of Quelimane presents little of interest in the nature of natural forest, consisting entirely
of mud flats cleared of the original bush and now under cocoa-nuts, rice or manioc, in accordance with its dryness, the back country consists of unbroken forest of high technical value and of much botanical interest. It is mostly evergreen and broad leaved, dense enough to yield straight clean timber, open and level enough to be
easily worked, and on sufficiently good soil to yield good crops where it is cleared.

6 Forest Flora of Portuguese East Africa.
Rubber abounds, both Landolphia Kirkii and Mascarenhasia elastica being present in quantity, though the amount collected is meantime small. The valuable
imbilo timber (Pterocarpus) is present everywhere, though of special quality in the fine valley known as the Raraga Forest; Magundo (Milicia) is seldom absent and often of enormous size; several hardwoods known rather confusedly as pau-ferro, naquada, and pangira are abundant; Brachystegia, Parkia, Bauhinia and Cordyla are common and of considerable size, while the Tamarind and the Mango (probably introduced long ago) are scattered throughout the forests in what now appears
indigenous growth and of enormous size, and the exotic Eriodendron (Kapok) and Bombax are rapidly taking similar positions.
Several Euphorbiaceous trees under the common name Umtela are common and of timber value, while Combretum and Terminalia species are also valuable
hardwoods of large size.
The scented muconite (Exccecaria) is local but very fine, Mugonha (Adina) makes a fine tree and valuable timber along the streams, Khaya and Sorindeia form
very large trees near water, and the Flat-crown (Albizzia fastigiata), now worked scarce in Natal, is abundant and of fine form, without damage. Anacardium (Canjew) is the most common tree in abandoned land formerly cultivated; Sclerocarya is its frequent companion; the Orange is not uncommon where a kraal has at some time
existed, and lentils (Ervum lens) in a semi-naturalised condition abound.
The forest varies much in density; the valleys along several rivers such as the Raraga and the Lecungo contain very fine material in enormous quantity; the
higher ground is of lighter material, say 22 to 3 decametres diameter and 20 metres height, equally spaced at about 7 metres distance. This latter material is the product of light sandy soil, and would never grow larger under present circumstances; there is no undergrowth and no dead material standing or lying about ; presumably the white ants (Mchai) speedily destroy all soft dead wood, though several of the hardwoods are proof against white ants and have remained intact in buildings for many
years. The absence of Baobab and the scarcity of Trichilia emetica in the forests of Magenja da Costa is notable.
The Companhia de Zambesia (Manager, Capt. S. Munish) is opening up a timber business in its Messingire Forests, which extend north of Mopea and along
the Shire River; the Luaba Co. (Manager, Senhor Bon Souza) is working in the extensive Marral Forests nearer Quelimane and building boats, lighters, &c. ; the Boror
Co. (Manager, Count Stucki) utilises the timber it clears for plantation work, in so far as demand exists, as also does the Madal Co. (Manager, Sr. Bouvay).
Taking this region as a whole, there are many thousands of square miles of actual forest of high quality, still waiting the advent of the lumberman.
The districts of Tete and Mozambique add considerably to the number of species of trees, and consist for the most part of forest similar to that in Quelimane, but in the tidal mud near the coast the amount of workable mangrove is considerably greater. The Northern district, worked by the Companhia do Nyassa, extending as it does from the Indian Ocean to Lake Nyassa, naturally introduces many additional species, of which only those along the Rovuma River on the northern boundary are well known. According to the "Annuario de Mozambique," 1908, the products of the district are :-Earthnuts, sesame, caou and chouc (Ficus and Euphorbiaceae), copal, gum, ebony, cocoanut, wax, vegetable wax (Myristica ocuba), "arroz," mapira (Kafir-corn), mealies, anil, sugar, pimento, ricinus (castor-oil), tobacco, coffee, cloves (= cravo), baobab, &c., as also these timbers :-Sandal, Teak, Pau-ferro, Mogno (Khaya), Caju (Anacardium), &c.
My own mission did not include the Nyassa Company's area nor the districts of Mozambique and Tete, but a considerable amount of information has been obtained which is included here in regard to the species concerned.

below and suddenly reduced into comparatively small horizontal branches, on which the twigs are 1-2 c.m. diameter up to the abrupt point and hairy at the apex.
petiole 12-16 c.m. long; leaf digitate, about 8-foliate; leaflets 1o-15 c.m. long, widely lanceolate or oblong-acuminate, entire, wavy, somewhat pubescent below, tapering to a petiolule at the base. Peduncles axillary, i-flowered; calyx-lobes 5 c.m. long, leathery, hairy inside; petals 2-3 times as long in large flowers, rounded, plaited; column 4 c.m. long, bearing in the upper part many filaments bearing i-celled anthers. Flowers produced before the leaves. Fruits oblong, 8-16 c.m.
long, 7-9 c.m. diameter, containing acidulous refreshing pulp among the seeds. Scattered over most of Tropical Africa and Asia, but not present everywhere. It is not uncommon in the neighbourhood of Inhambane, extending south to Inharreme (extra-tropical), but though Peters gives "along the whole coast" as its habitat in Mozambique district, I did not see a tree of it in Quelimane, Magenja da Costa or Nhamacurra. It occurs, however, further up the Zambesia in the Tete

29 BOMBAX. Calyx tubular, truncate; corolla of 5 petals connected with the base of the column; staminal tube slender, 2 c.m. long, then divided into 5 lobes, each of
which divides in pinnate manner into about 20 stamens with long slender scarlet filaments, and 2-celled or occasionally 3-celled anthers; ovary 5-celled with many ovules in each cell, soon i-celled with 5 rows of ovules (about 5 in each row) set on a central axis; capsule coriaceous, dehiscent, containing numerous seeds
embedded in wool.
B. Buonopozense, Beauv. Vern. names-2, Simonia; o10, M-kungo. A large or very large, nearly deciduous, glabrous tree, with more or less whorled and horizontal
branches, ascending branchlets, and decorticating glaucous bark. Leaves petiolate, alternate, digitate, with about 6 leaflets, each 3-10 c.m. long, I'5-3 c.m. wide, obovate, pointed, and shortly petiolulate. Flowers numerous in axillary clusters of 2 to 1o, either on separate 1-3 c.m. pedicels jointed near the base or 2-3 together on a very short common peduncle. Calyx-tube 1'5 c m. long, i c.m. wide, with 5 very short teeth and minutely pubescent; petals 5, scarlet, 5-7 c.m. long, I c.m. wide, usually the upper 3 together and the other 2 separate; stamens as long as the petals; pistil longer or shorter than the stamens; style slender, hairy below the stigma, somewhat arched, scarlet. Capsule o10-15 c.m. long, many seeded, the seeds set in red wool. A tree evidently introduced long ago to Quelimane, now more or less naturalised for a long distance round but also planted as a street tree. One specimen at Arenga is 4 metres diameter, io metres bole, and 20 metres

height. It occurs also in West Africa. This and Eriodendron are hardly differentiated by the public; they have similar habit, bark, leaves and pods, and are given the same names and used for the same purposes, principally for use as dug-out boats. A tree of rapid growth and soft timber; the colour of its wool is against that
being favoured as a commercial commodity.

papery dissepiments. Fruit a coriaceous dehiscent capsule io-15 c.m. long, the seeds bedded in cottony wool. Leaves digitate.
E. anfractuosum, D. C. Vern. names-I, Kapok ; 2, Simoma or Somba-umba; io, M-Kungo. A large erect tree 20-30 metres high, with stout straight trunk,
horizontal more or less whorled branches, ascending branchlets, and decorticating glaucous green bark, occasionally with a few stout prickles toward the base which disappear from old trees. Not regularly deciduous but mostly so; perhaps deciduous in all cases sometime during the year. Leaves irregularly alternate, 1"5-3 c.m.
apart on stem, digitate, 5-7 foliate, glabrous, green above, pale under; the petioles 15-20 c.m. long, adhering to the branch after the leaflets disarticulate.

Flowers profusely produced on the previous year's wood, short warts in the axils producing 2-1o flowers each on terete s-flowered peduncles 2'5-5 c.m. long. Calyx green i'5 c.m. long, i c.m. wide, secreting nectar as it matures and nearly truncate, with 5 rounded lobes. Petals 5, 2-5-4 c.m. long, concave, rounded or bluntly pointed, yellowish-white spreading, canescent outside. Style swollen at the base on i side and connected by a constriction to the ovary, decumbent as also are the staminal bundles more or less, these looking like 5 stamens. Seeds numerous, bedded in white cottony wool which is an article of commerce elsewhere for packing fruit, filling pillows, &c.
Imported long ago to Quelimane, now spontaneous in many parts of that district. It occurs also in West Africa and in East and West Indies, and is planted
throughout the tropics. The greenish smooth bark of this and Bombax as well as of several species of Sterculia and Cola is a marked character.

Among other local economic plants belonging to Malvaceae may be mentioned:Sida, several species; small semi-herbaceous plants containing strong fibres which are fit for ropemaking and textile purposes. They are scattered through the Province but not utilised, and even in other countries their cultivation is seldom seriously taken in hand.
Abutilon, several species of perennial undershrubs, sometimes 8-io feet high and always having useful fibre in the bark. One species is used for cordage in the M'Chopes under the name Nytebasian, and the same or a similar species is similarly used in Lourenzo Marques district under the name Nuce, but neither has
been cultivated.
Urena lobata, Linn. A virgate undershrub, widely distributed over the warmer parts of the world, is frequent in the cultivated lands from the Limpopo northward, apparently as an introduced weed. It has, however, a valuable fibre, which is used undressed for cordage, and the plant is known in M'Chopes as
Sosowa. Probably its cultivation for fibre may be worth taking up.
Hibiscus, several species produce useful fibres, particularly H. cannabinus (2, Ambar), which is frequent in cultivated lands throughout the Province, and has probably been introduced from India where its fibre is a considerable article of commerce. H. Subdariffa is also frequent as a cultivated or escaped plant and
used for various culinary purposes, this being the Roselle of India, and the source of the beautiful Sorrel Jelly of Natal.
Gossypium, the Cotton plant, occurs frequently, in a more or less naturalised condition, but is probably not originally indigenous, or at least the only species which may be claimed to be so is a form of G. herbaceum having short brown cotton which is not uncommon in the forest glades of Magenja da Costa, where it is known as Iganfoge, while the long-stapled white cotton found near the kraals is known as Mftodye there, and as Bushale at Lourenzo Marques. Cotton is cultivated to a small extent by the Companies near Beira and Quelimane, but it can hardly be called a local industry so far, while among the natives its cultivation
is as a curiosity rather than for its fibre.
'Applied also to Bombax.

The "Wild Cotton" common throughout the Province as a creeper does not belong to this Family, but is Ipomaea albivenia, which has not yet been turned to account for textile purposes.
Flowers regular, hermaphrodite or unisexual. Calyx gamosepalous, 5-lobed or 5-fid; petals absent, or 5, free, contorted in aestivation, more or less attached to the base of the staminal column. Stamens with filaments united into a column or connate at the base, either with or without staminodia. Ovary free, 2-5 celled or of 2-5 more or less free carpels; cells several-ovuled. Fruit various. Leaves usually alternate and stipulate; pubescence often stellate; inflorescence usually axillary, either solitary, racemose or paniculate. A large Family, widely distributed. The larger trees have usually soft, white timber; cocoa, chocolate, cola and gum tragacanth are products; several yield valuable fibre barks, and in horticulture Brachychiton, Sterculia, Dombeya, Hermannia, and others are floral favourites.
31. STERCULIA. Flowers unisexual; calyx cup-shaped, 5-fid or 5-lobed; petals absent; staminal column bearing many extrorse anthers, crowded without arrangement;
ovary of 5 partly coherent carpels, with several ovules in each; ripe carpels separate, coriaceous, dehiscent, i or several seeded; seeds albuminous, albumen adherent to the cotyledons, so liable to be overlooked. Leaves alternate, simple or lobed or digitate; inflorescence in axillary or terminal panicles. A large
tropical and sub-tropical genus of trees and shrubs, usually with glaucous bark.
S. Triphaca, R. Br. A large tree with roundish or 3-lobed cordate petiolate leaves, 10-13 c.m. long, nearly glabrous on both su faces, and with the lobes acuminate and
entire, the central lobe largest. Inflorescence a much-branched axillary panicle, 5-6 c.m. long with the flowers on short jointed pedicels. Calyx i c.m. long, 5-lobed, canescent outside, pink and glabrous within. Column shorter than the calyx; follicles 3-5 spreading, ovate-acuminate, downy. Seeds arillate on a villose
placenta. Zambesi (Dr. Kirk), Senna (Peters).
S. tomentosa, Guill. Vern. name-io, M'lola, which name is applied to several fibre-producing trees. A medium-sized tree with smooth glaucous bark. Leaf 7-lo
c.m. wide, nearly as long, cordate at the base, palmately 5-7 veined, and wiih 3 wounded lobes and 5 c.m. petiole; both surfaces tomnentase with stellate hairs, or the upper surface ultimately glabrescent or rough; the lower surface closely reticulated. Flowers and fruit not seen by me, but described as being in much-branched axillary panicles; calyx 1-5 c.m. long, cup-shaped, 5-fid, downy; carpels 3-5, sessile, densely tomentose, with numerous purplish seeds and yellow horny arils.
This species occurs in other parts of Tropical Africa but is not previously recorded from here, and I am not sure that my specimens, which are from large trees in the forests of Magenja da Costa, belong to it, which has the lobes described as acuminate; if not they appear to be an undescribed species, but as they are leafspecimens only, the material is too imperfect for further description. Sim 5978.

S. quinqueloba. (New species.), Vern. name-io, Gampheba. A large tree with smooth glaucous or nearly white decorticating bark, which is red when cut. Leaves
z7-3o c.m. wide and long, 5-lobed from a cordate base, 5-veined from the base, softly pubescent or at length glabrescent above, the under side densely set with permanent soft whitish stellate pubescence mixed on the veins with longer hairs; lobes acute; petiole 15-45 c.m. long, hairy. Leaves more or less crowded toward the end of the branch, with inflorescence in axillary panicles in the upper axils. Panicles o10-2o c.m. long, often much branched, main rachis hairy, pedicels buds and flowers pubescent; calyx bell-shaped 5 m.m. long, 5-lobed; anthers about 15 crowded on top of the column; carpels about 5, 8 c.m. long, spreading, oblanceolate, acute, opening at maturity, densely grey-velvety outside, and with white pubescence inside. Seeds i c.m. long, purplish-black. I think this is not Cola quinqueloba, Garcke; at least this is a Sterculia with crowded stamens and albuminous seeds. Differs from S. tomentosa and S. cinerea as described in size and
outline of leaf, size of flower, &c. Frequent in alluvial soil in Magenja da Costa and Nhamacurra (Tropical). Timber white, hard, not used. Sim 998.

A species of Sterculia (Sim 6277 and 6328) known as (4, 15) Mforkonwan, is frequent in the Lebombo range as a shrub 2-4 metres high with a stem 30-60 c.m. diameter at the ground, but immediately divides into many spreading glaucous branches. No mature leaves were seen; the very young leaves were nearly glabrous, and more or less cordate, the flowers produced in sessile clusters of 3 to 5, each flower on a pedicel 5-o10 m.m. long; calyx cup-shaped, 5-lobed, I"5 c.m. wide, with white stellate pubescence outside as well as toward the points of the purplish striated lobes inside; column i c.m. long with about 15 crowded anthers; carpels 2-4, densely tomentose, rostrate when young, ultimately firm, 3 c.m. long, 4-5 seeded, and with stellate pubescence outside and inside. Young wood warty, old bark smooth and glaucous. This is apparently an undescribed species, but in the absence of leaves must remain unnamed for the present. Other 2 unnamed species are mentioned in the "Flora of Tropical Africa" from the Rovuma, concerning which I can add nothing.
An introduced Sterculia forming a large straight tree with digitate leaves occurs in and around Quelimane, hardly naturalised as yet, though likely to be so soon, which in general appearance and habit resembles Bombax and Eriodendron. It is known by the Portuguese name Pinko.

ovary 5-o10 celled, ovules numerous; carpels 4-5, free, leathery, dehiscent, with 3-6 exalbuminous seeds. Leaves simple. An African genus, of which I species C. acuminata is an important factor in the commerce of Tropical West Africa, as its seeds are the Kola-nuts, used as a nutritive stimulant and in the preparation of
an aerated water, &c. i species occurs in Natal.
C. cordifolia. (New species) = Sterculia cordifolia, Guill. & Perr., Fl. Seneg. I. 79, t. r5. Vern. name-io, Impeba. A large tree. Leaves alternate, cordate, acute,
or sometimes 2-3 pointed, 5-7 nerved from the base, finely stellate pubescent on both surfaces, 7-1o c.m. long and wide, with a pubescent petiole 5-8 c.m. long.

stem. Leaves io c.m. long and wide, or larger, cordate, hard, finely toothed, rather rough, with fine stellate pubescence above, and more dense below, 5-7 veined at the base, and with numerous cross-veins in relief. Petiole 5 c.m. long, minutely pubescent. Inflorescence axillary, abundant, cymose pubescent; cymes many flowered, 7-15 c.m. long, flowers 2 c.m. wide, sepals lanceolate. Frequent between Arenga and Maquebella, Magenja da Costa, where the fibre of the bark is used
for rough cordage. Sim 5966.
D. Kirkii, Mast. A shrub or small tree unknown to me but described as having the younger parts covered with dense stelliform tomentum. Leaves petiolate,
cordate-ovate, acuminate often more or less 3-lobed, the lobes acute or acuminate, coarsely and irregularly crenate-serrate. Peduncles axillary and terminal, longer than the leaf stalks; pedicels slender 2"5-5 c.m. long with spreading villi. Flowers small, sepals oblong lanceolate; petals obliquely cuneate, retuse, double the
length of the calyx. Filaments free nearly to the base; ovary downy; stigmas 2-5, included. Lat. 160 S., Dr. Miller; Lupata, Sir John Kirk.

Occurs in Natal, and occasionally throughout the Province; it is used by the natives for the production of fire by friction; its fibre is occasionally used, and it is well worth
cultivation for its flowers. Sim 5726.
Another species of Dombeya, perhaps D. Natalensis, Sond. occurs at Delagoa Bay and is known as Sicara, but only incomplete material was obtainable.
Flowers hermaphrodite; sepals 4-5; petals 4-5; stamens many, filaments free, hypogynous or rising from a torus; anthers 2-celled, introrse. Ovary 2-4 celled, 2-manyovuled; style single; stigmas as many as the ovary cells. Seeds albuminous. Leaves simple alternate, stipulate.

Petals 5, each with a gland at its inner base. Stamens numerous, free, ovary 2-4 celled with a simple style; drupe 1-4 lobed, each lobe containing one 1-2 seeded stone. Cymes axillary, 1-4 flowered. A genus of straggling or subscandent shrubs of no practical utility of which 17 species are recorded from Mozambique Province and io from South Africa, 3 only being common to both. See "Forest Flora of Cape Colony," Plates XV. and XVIII., for G. lasiocarpa; G. occidentalis and G.
flava, and "Natal Plants," Plate 42, for G. caffra, all of which belong to our district. The natives use the branches in the construction of fish-kraals, and occasionally eat the fruits, though there is little quality in them. The species are not well distinguished either by natives or botanists, but the following vern. names are in use in the group:-4-5-6, Suiss and Mbodwa; 7-8, Tchapande; io, Impara; ii, Maitomatorulo. The name (4) Shamunyamanyan is also used for this and other
similar shrubs.

wings. Seeds solitary in each cell, pendulous. Albumen fleshy. Trees with entire or cordate leaves. Flowers small, in axillary cymes."
This genus was founded on a Cuban plant, the following species from the Rovuma was added in the "Flora of Tropical Africa," and now with considerable hesitation and in the absence of flowers I have added a third species.
C. africana, Mast. A tree from the Rovuma River having oblong, acute, sometimes obscurely lobed, i-nerved, long-petioled, pilose leaves 10o-15 c.m. long, and extraaxillary peduncles 5-7 c.m. long, dividing into 5-6 cymose pedicels each about 2'5 c.m. long. "Capsule sub-globose, 2-valved, i-celled, each valve provided with 2
unequal, obtuse, foliaceous wings i or 2 inches in length, J-1 inch in breadth. Seed solitary, pendulous, villose."
C. minor. (New species.), Vern. name-4, Incalago. A glabrous shrub or small tree 3-4 metres high, frequent on the Polana, Lourenzo Marques, having alternate,
obovate, shortly petioled leaves 3-5 c.m. long, 2 c.m. wide, and supra-axillary i-flowered solitary peduncles 1-I15 c.m. long. Flowers not seen; fruit 2-celled,
consisting of 2 compressed samara-like carpels, attached to a central placenta, from near the top of which the seeds are pendulous. Carpels 2 c.m. long, each i-seeded, and with an oblique membranous dorsal wing 2'5 c.m. long, 2 c.m. wide. Seed compressed, pendulous obovate, albuminous. The raw juice of the
leaves and stem is used by the natives instead of soap. Sim 5555.
Flowers hermaphrodite, regular. Sepals 5 ; petals 5; stamens about io, the filaments united at the base into a cup; ovary free, 3-celled, cells i-ovuled. Leaves entire, alternate. Mostly herbs in temperate regions, but with a few trees and shrubs within the tropics; widely dispersed.
38. ERYTHROXYLON. Flowers axillary, solitary or fascicled. Petals imbricating, deciduous, white, each furnished near the base on the inner surface with a 2-lobed
scale, each lobe scarious and emarginate. Filaments connate J of their length. Ovary free, 3-celled with solitary ovules. Styles more or less connate. Drupe of 3 cells, but only f of them fertile, i-seeded. Seed albuminous. Glabrous tropical trees. The name, meaning redwood, is derived from the colour of the wood

E. monogynum, Roxb. A small tree, with stem up to 45 c.m. diameter, often a much-branched shrub. Twigs compressed and somewhat distichous, older branches
terete. Leaves obovate, coriaceous, entire, glabrous, pale or glaucous on the under surface, 2-5-7 c.m. long, 1-3 c.m. wide, rounded at the apex and rounded or tapering to the 5-7 m.m. petiole. Stipule axillary, scale-like, caducous, keeled. Peduncles axillary 1-2 c.m. long. Fruit i c.m. long, oblong, red or purplish, of 3
equal cells but only i fertile and I seeded. Present but not common throughout the Province, as also in Natal, Eastern Cape Colony, Transvaal, West Africa, India, &c. A variety with smaller and more cuneate leaves, pale under, and longer peduncles, found in Gaza and Transvaal, may be specifically distinct. Included here are E. caffrum, Sond.; E. pictum, E. Mey.; E. emarginatum, Sch. & Th. (" Flora of Tropical Africa," I. 274), and Sethia indica, D.C. See "Forest Flora of Cape
Colony," 15o, Plate XVII. fig. i. In Magenja da Costa this was named na-ire, but I doubt the correctness of that name, which is used as synonymous with

C. capense, Thunb. Vern. names-i, Wild Chestnut; 13, Umbaba; 14, Wilde Kastanje. A large umbrageous tree with opposite, decussate, exstipulate, simple, ovate
or ovate elliptical, glabrous leaves 8-12 c.m. long, 3-8 c.m. wide, and inflorescence as described above. I did not see this tree in the Province, nor is it included in the Flora of Tropical Africa," but it is included here on the strength of Dr. Bolus' statement (Oficial Handbook of the Cape, 1893, page zo3) that it has been met with on the Zambesi and even on the Kilimanjaro Mountain, a few degrees south of the equator; it is, however, not included in Miss Gibb's list of plants of Southern Rhodesia nor in Mr. D. E. Hutchin's Report on the Forests of Kenia, and I now think it probable that my own statement that "experiments are being made in East Africa to collect the seeds commercially for the expression of oil" is founded on mistaken identity, and should have referred to Trichilia. See "Forest Flora of
Cape Colony," 153, and Plate XXI.

coat of the capsule and fully exposed or projected for some time after dehiscence. Seeds bony, albuminous. Leaves pinnate, alternate.
X. capense, Sim ("Forest Flora of Cape Colony," 155 and Plate XXIV.). Vern. names- i, Knobwood; 4, Um-hlungwaan; 5, 6, 7, 8, Nungwane; 13, Um-nungumabele; 14, Paardepram. An exceedingly variable tree, frequent throughout South Africa, and also throughout the Province of Mozambique. In Cape Colony it forms a large and valuable timber tree with leaves 30 c.m. long, bearing 6-8 pairs of leaflets, and stems so set with large prickle-pointed corky knobs as to earn its name Knobwood, and this form was seen in Gaza, but smaller forms occur merging gradually into these. What were seen elsewhere in the Province had leaves about 5-foliate, 15 c.m. long; pinnules 5 cm. long, widely lanceolate, crenate, bluntly pointed, tapering to the i c.m. petiolules, with or without prickles on the

I. (?) mossambicensis. (New species.)' Vern. names--o, II, Tube and Tumbe. A large tree with leaves ovate-elliptical, 5-8 c.m. long, 2-3 c.m. wide, firm, broadly
pointed, rounded at the base, entire, glabrous when mature, with prominent midrib and numerous nearly parallel side veins. Coppice shoots have leaves o-15 c.m.
long, 4-5 c.m. wide, more cordate at the base, finely white-tomentose on the under surface, brown-woolly on the upper surface, but this wears off with age; probably on the trees this is so also, but the long bare stems render foliage almost inaccessible. Coppice shoots also show stipules 2 c.m. long, which, like the petioles and young growth, are covered with brown pubescence, and the leaves in bud have the margins rolled outward. Older wood and fruit covered with white lenticels. Fruit terminal, showing no vestige of style or calyx, oblong, 3-4 c.m. long, 2-3 c.m. diameter, having a firmly fleshy edible epicarp and a hard bony 2-celled stone, each cell lined with an abundant silky wool, and containing i erect oily-albuminous seed. Flowers and inflorescence not seen ; in the absence of these the generic position of this tree remains uncertain. Tree 20-30 metres high with clean straight valuable timber stem ; fruiting very abundantly; the fruits readily eaten by the monkeys, and when they fall by the natives, rather sweet, not quite a table fruit but acceptable to the weary traveller. See Chap. IV. Frequent in the forests of Quelimane,
Magenja da Costa and Nhamacurra, usually of timber size; young trees scarce. Sim 5622.

Naturalised throughout the Province, but less prosperous at Quelimane and northward than in the south.
51. EKEBERGIA, Inflorescence paniculate; panicles numerous, placed singly in the axils of the new season's leaves, and thus crowded at the ends of the branches.
Flowers polygamous or apparently hermaphrodite, jointed to the pedicels. Calyx irregularly 5-fid; petals 5, imbricate in bud, slightly adnate at the base to the staminal tube; stamens ro, their filaments united into a tube, on the margin of which stand the anthers; ovary sessile, surrounded by a ring, 2-5 celled; cells 2-ovuled; style short; stigma discoid or somewhat 2-lobed.

T. emetica, Vabhl. Vern. names-i, Cape Mahogany; 2, Mafurreira; 4 to 8, the Portuguese name Alfaurreira, or various alterations of the Kaffir name (13) Umkukul,
such as Nkusu, Tunhlu, Umcuch6, Kuhlu, &c. ; io, Muteri and Moreka; ri, Mutumbe ; 14, Esschenhout. The fruit is known to most natives by the Portuguese name Mafura. A large, evergreen, umbrageous tree; leaves imparipinnate of 3-5 pairs of leaflets and a terminal one, 15-30 c.m. long, 15-22 c.m. wide; the leaflets opposite, lanceolate-oblong or oblong, acute or obtuse, entire, glabrous, shining, dark green above, green or pubescent below, 8-T2 c.m. long, 4-5 c.m. wide, on short swollen petiolules. Flowers numerous on short clustered axillary panicles, forming together a large much-branched or clustered terminal leafy panicle. Flowers scented, usually (or always) imperfectly dicecious, some trees having only potent stamens and others only potent pistils in flowers which appear hermaphrodite, the result being a heavy crop of fruit annually on the fertile trees and never any on the others. Flower 2 c.m. across, 1-5 c.m. deep, staminal tube cylindrical, hairy upward, shortly io-toothed, each tooth bearing an extrorse anther set in hairs. Pistil approximately the same length as the staminal tube, but varying in length, possibly in connection with potency. Fruit leathery, globose or nearly so, 2-2'5 c.m. diameter, 3-valved, 6-seeded or fewer. Seeds black, 1"5 c.m. long with scarlet arillus, from which, as also from the seed, oil is obtained in quantity, making this one of the most useful trees in the Province. The Portuguese name of the fruit, Mafura, means oil, and one of the synonyms of this tree is Mafureira oleifera (Bert. Misc. Bot. IX. 6, t. 2). Distributed abundantly throughout the Province south of Inhambane, both on the sandy ground and on the alluvial river flats, present also in the tropical parts of the Province, though less abundant and hardly used

Unknown to me, but several trees more or less answering the above leaf description were seen without flowers or fruit and it may have been one of them as it is included also in the list of plants found in Gaza, in Gaza" (by Capt. Gomnes da Costa, 1897-1898, Lisboa). One of these known as (4 and 6) Shimbunkanye, found abundantly along the Umbelusi, Lourenzo Marques, and seen also in M'Chopes, has a most extraordinary development of brown wool upon the roots underground, and is on that account credited by the natives with marvellous
powers of preventing snake-bite, goat-sickness, &c., but in the absence of flowers or fruit it was impossible to identify it.
53. CARAPA. Glabrous trees with pinnate leaves, small flowers in cymose axillary panicles, and very large fruits. Calyx 4-lobed; petals 4; stamens monadelphous;
anthers S ; ovary about 4-celled, with several ovules in each cell. Capsule large, woody, opening in 4 valves. Seeds large, angled by pressure.

12 in each cell. Capsule woody, dehiscent; seeds albuminous, about I2 in each cell, flat, shaped by compression. Leaves abruptly pinnate.
K. senegalensis, A. Juss. Vern. names-2, Mogno (=Mahogany); so, Monondwe and Mbowa. A very large glabrous, evergreen tree, present but not common
throughout all the forests north of the Zambesi, and stated to occur also in the tropical forests south of the Zambesi ; usually growing near a stream. Owing to its long clean stems I failed to obtain normal leaves; that drawn is from a coppice shoot. Leaves abruptly pinnate, 4-1o foliate, 15-30 c.m. long or longer; with no terminal leaflet though the upper one sometimes appears so; leaflets opposite, sub-opposite or alternate, elliptic or elliptic lanceolate, acute, rounded or tapering at the somewhat oblique base; petiole 7-14 m.m. long. "Panicles shorter than or nearly equalling the leaves, with ascending or spreading lateral branches decreasing in length from below. Flowers cymose, usually in 3's, or peduncles trichotomous. Pedicels shorter than the flower. Bracts minute, ovate-deltoid." Fruit 5 c.m.
long, 4 c.m. diameter, the 4 woody valves splitting apart round the central woody 4-winged axis, each cell having about 12 seeds in 2 rows. Sim 5547. Occurs also
in West Africa and on the White Nile.

longitudinally. Style single, central on the disc, the 4-6 ovary-lobes arranged around its base, each i-celled, i-ovuled, and after fertilization appearing as 4-6 separate black drupes resting apart upon the red enlarged torus, and the calyx often turns red also. Seeds albuminous. Leaves alternate, simple, stipulate; stipules deciduous. Owing to variable characters the species are difficult to separate. A large tree from Magenja da Costa known as Nakrokwe, seen only with immature
flowers, may belong here or to Uvaria.
O. arborea, Burch. Vern. names-i, Redwood and Cape Plane; 4, Mzenzan and Shukwa; 13, Umtensema, Umhlezane and Umtelele; 14, Roodehout; 15,
Shimushwan. A small tree 4-12 metres high, usually having a small crown and a clean unbranched stem 15-30 c.m. diameter with a thin white or brownish smooth bark, from which scales flake off. Leaves oblong, entire or few-toothed, coriaceous, 5-7 c.m. long, 1-2 c.m. wide, usually obtuse, very shortly petiolate; flowers produced abundantly, singly or in racemules or clusters, often from abortive branchlets. Anthers dehiscing by terminal pores. Frequent in the extra-tropical districts ; yields a dense, close-grained, light red, durable timber in Cape Colony and Natal, where it is used for various purposes. Cone-like galls often occur instead
of buds. Leaves generally more serrate than in Natal.

flowers in lateral pedunculate corymbose racemes. Anthers opening by pores. Throughout the Province.
O. atropurpurea, D. C. var Natilitia. Vern. name-iS5, Mtuse. A tree with lanceolate, undulate, sharply serrulate leaves 5-7 c.m. long, 1-2 c.m. wide. Flowers in
short lateral racemes, anthers opening by pores. Delagoa Bay, M'Chopes and Inharreme.
O. Kirkii, Oliv. Vern. names-io, Ka-mulugaim; ii, Nequaka. A large glabrous tree in the forests of Magenja da Costa. Bark very rough. Leaves obovate-elliptical
to oblanceolate-oblong, 5-7 c.m. long, 1-2 c.m. wide, sometimes cordate at the base, finely serrulate, prominently and irregularly veined above, pale below. Resting buds abundant. Flowers not seen; said to be in terminal or lateral pedunculate, umbellate corymbs, and with anthers dehiscing by short slits. Recorded also
from Rovuma.
O. macrocalyx, Oliv. A small shrub from Zambesia and northward having serrulate, oblanceolate-oval, sub-acute leaves 7-10 c.m. long, 2-3 c.m. wide; short axillary
3-7 flowered racemes; flowers large; pedicels 2"5 c.m. long, fruit sepals 2-2-5 c.m. long. Anthers dehiscing by pore-like slits.
Flowers hermaphrodite or polygamo-diecious; calyx 3-4-5 lobed or partite, petals 3-5 ; stamens 6-8-io, inserted on the margin or on the outside of a fleshy disc more or less attached to the calyx tube; ovary free, 2-5 celled ; ovules geminate; fruit drupaceous or capsular; seeds exalbuminous. Trees and shrubs with alternate, exstipulate, 3-foliate or imparipinnate leaves and small axillary paniculate, racemose of fascicled inflorescence. To this Family belong several of the resin-bearing trees of Somaliland, and I think it probable that several large deciduous pinnate-leaved trees having more or less flaky bark, and found by me in Zambesia without flowers or fruit and almost without leaves may also belong here. Canarium, a West African edible fruit, is mentioned in Gaza" as found there, but I have no other information that it is so.
56. COMMIPHORA. Flowers polygamous. Calyx companulate or deeply 4-toothed, persistent. Disc almost absent or adnate to the calyx and more or less cup-shaped,
bearing the 4 perigynous valvate petals and 8 stamens on its margin. Filaments slender, free, alternate stamens slightly shorter. Pistil rudimentary in most flowers.
"Ovary 2-3 celled, narrowed into a short thick style stigma obtuse, undivided, or margins lobulate. Ovules geminate, collateral, pendulous." Drupe ovoid or sub-globose, usually i-seeded, the leathery or somewhat succulent mesocarp dehiscent in 2 valves, exposing the black bony putamen, the lower half of which is girt by a bright red aril-like tissue; seeds exalbuminous. Cotyledons plicate. Leaves 1-3 foliate or pinnate, deciduous, usually the first leaves on new shoots are i-foliate, the number of leaflets increasing up the stem. 5-merous flowers are occasionally intermixed in the same inflorescence among the normal 4-merous flowers.
Timber very light, white; bark usually separable in horizontal flakes, leaving a shining green surface. A difficult group to limit in regard to species, and the natives confuse the species considerably in the use of the common names. In the absence of literature on the Commiphore I do not feel justified in naming the species which are new to me, and consequently refer to them by numbers. Possibly the Shumbunkanye" referred to under Trichilia Capitata belongs here-(6) O-deba
or Diva. All the species strike by stump-cuttings and are planted for hedges, shelter, &c.
C. africana= Balsamodendron africanum Arn. in Ann. Nat. Hist. III. (1839) 87. Flowers in axillary fascicles, mostly on short leafy spine-branches. Leaves 1-3 foliate,
leaflets 2-3 c.m. long, 1-2 c.m. wide, nearly sessile, obovate or oblanceolate, cuneate at the base, blunt or acute, crenate or nearly entire. Fruit globose or obovoid,

almost sessile, i c.m. long, red, with a marked aril. Said to be the source of the gum known as African Bdelium. There are at least 2 varieties, viz.:(a) Normalis. Vern. name-io, Na-loa. More or less pubescent; leaves obtuse, crenate-serrate.
(b) Alyssinica. Vern. names-4, Chessengue; 15, Imbendong. Glabrous ; leaves more narrow and acute, not deeply crenate, 1-3-5 foliate. Var. norma/lis is frequent as a shrub or small tree north of the Zambesi, and var, abyssinica is abundant throughout the southern half of the Province, and is
often planted as an exceedingly rough spinose hedge. The fruit is eaten in Magenja da Costa as a stomach medicine. Trees seen at Umbelusi (Sim 6225), and which had the same fasciculate inflorescence were rather large trees, abundantly spinescent, with leaves 1-3-5 foliate, and were named Chessenque-nkomo by the
C. mossambicensis, = Protium (?) mossambicense, Oliv. ("Flora of Tropical Africa," I. 329). "Leaves 3-foliate, rarely sub 5-foliate, at length glabrescent ; leaflets
broadly ovate-rotundate, broadly pointed, sub-acute or obtuse, entire or faintly undulate; median 3-31 in. long, i-3 in. broad, on a petiolule of j-1 in., lateral i1-2 in. long and broad, on petiolules of 1_1 in. Fruits racemose from the axils of fallen leaves, broadly ellipsoidal or sub-globose, about in. in length; epicarp

tardily 2-valved." Described by Prof. Oliver from specimens sent from the Zambesi by Sir John Kirk, in fruit only; it is unknown to me but is included in the list
of Gaza plants in Capt. Gomes da Costa's Gaza."
C. caryaefolia. Oliv. Iern. names-i, Corkwood; 4, Shumbu-n-kanye; io, M-tula'; 13, Hlunguti. Flowers sessile in lax spikes 6-1o c.m. long, axillary to the lower
leaves on young branches, or below them. Leaves deciduous, 20-45 c.m. long, imparipinnate, 7-9 foliate (or up to 21 -foliate ?); leaflets oblong-lanceolate, rounded at the base, acute, 7-12 c.m. long, 2-2"5 c.m. wide, crenate serrate, villose and stellate canescent when quite young, afterwards glabrous, coriaceous, and turning yellow before they fall. Resting bud set with acute scales; spikes produced from among these scales, often before the leaves appear, or axillary to the lower leaves.
Calyx cut less than half way, lobes acute, disc attached to its cup ; petals perigynous, short, acute ; stamens short, perigynous ; ovary usually rudimentary. 1)rupe 2 c.m. long, i c.m. diameter, green, dehiscent showing a red pseudo-aril. A very large tree with rough bark and timber light enough to be used for floats in fishing, and as brake-blocks, &c. See Forest Flora of Cape Colony," page 158 and Plate XXV. Frequent throughout the Province. At Arenga (Magenja da Costa) the leaves are used as a poultice on sores. It is possible that the multifoliate tropical form is a separate species, and another form with entire leaflets may also be
specifically distinct.
C. Harveyi, Engl. Vern. names-i, Corkwood; 4, Chessengue-m-kanye; 6, Diva, Mumbu, Tchaikanyakanyan; 7, Chirol or Chival; io, N'Illovo; 12, Shrituana; 13,

Panicles axillary on the young wood, diffuse, io c.m. long, 3 c.m. wide, its branches 1-2 c.m. long, each subtended by a leafy bract. Flowers shortly petioled, 5 m.m. long and wide; calyx deeply 4-lobed, the segments lanceolate; disc almost absent; petals perigynous, oblong, acute, whitish, expanded; stamens 8, the alternate slightly shorter. Ovary usually rudimentary; perfect ovary not seen. Drupe 10-15 m.m. long, io m.m. diameter, green, dehiscent showing a red pseudo-aril. Old bark very smooth, green, peeling off in thin paper-like sections. Frequent throughout the Province, as also in Natal and Eastern Cape Colony. See Forest Flora of Cape Colony," page 158, Plate XXV. fig. 4, where, however, the panicle is congested, whereas the most common form in this
Province has a very lax panicle.
Commiphora species, No. I. (Sim 6395.) A medium-sized glabrous tree, found in the forests of Quisica, as also at Lourenzo Marques, having flaky green bark, soft
limber, alternate 5-7 foliate leaves with sessile, finely crenate, thin, obovate acute leaflets 3-5 c.m. long, i-I"5 c.m. wide, and axillary panicles 6-io c.m. long, branched at the top only; flowers not seen; fruits abundant, rostrate, 15 c.m. long, 8 m.m. diameter, greenish, I-seeded, dehiscent with 4-nate calyx remaining; seed black,
without evident aril.
Commiphora species, No. 2. (Sim 5915.) Vernz. names-io, Mamnatula and N'illovo. A medium sized pubescent tree found near Arenga, Magenja da Costa,
having I -15 foliate leaves with sessile, crenate, firm, elliptical, pubescent leaflets 3 c.m. long, i c.m. wide, and axillary wooly panicles in the upper axils, the panicles
lo c.m. long and branched at the top only; fruit almost sessile, globose, I c.m. long, with 4-nate calyx remaining. Axillary spines often present.
Commiphora species, No. 3. (Sim 5996.) Vern. name-lo, Periveri. A small glabrous tree with 1I1-13 foliate leaves about 45 long, the leaflets sub-opposite
or alternate, shortly petiolate, obliquely lanceolate, acute, undulate, entire, 15-20 c.m. long, 3-4 c.m. wide and abundant axillary panicles 45 c.m. long, much
branched, many flowered. Flowers not seen; fruit oblong, i c.m. long, almost sessile (dehiscent ?). Found near Maquebella, Magenja da Costa.
SThe name M-tula is used for Sclerscarya caffra, and it is possible that it was given to Commiphora through mistaken identity, as the leaves are somewhat similar.

A bitter or acrid principle is often present in the Family ; some species are poisonous, others have edible fruits, some yield valuable timber, and from the covering of the seeds in some species of Sapindus soap is obtained. Rather a heterogenous group. An erect shrub with pinnate leaves and 15-21 sub-opposite or alternate oblong leaflets 2-3 c.m. long, known as Mbrunya at Arenga, Magenja da Costa, probably belongs to this Family, but no flowers or fruit were seen. A decoction of its ground fresh leaves is used to wash fishing lines, and is said to kill the fish if put into the water in some quantity.
62. PAULLINIA. Flowers irregular, with a unilateral disc, polygamo-dioecious. Sepals 5, the upper 2 larger and connate; petals 4, unequal, and a scale; disc annular,

Leaves simple or 3-foliate, alternate, glabrous or glabrescent, often bearded in the axils of the veins. Shrubs, seldom of timber size, and only worth brief
description here.
S. monophylla, Presl. A large shrub or small tree with simple leaves 7-15 c.m. long, 4-7 c.m. wide, and flowers in lax racemes 5-15 c.m. long. Fruit pubescent till near

7o. BERSAMA. Racemes axillary or terminal on short side branches. Flowers apparently hermaphrodite. Sepals 5, nearly equal, the lower pair connate, imbricate.
Petals 5, unequal, irregular in form. Disc raised, unilateral; stamens 4-5, centrical, inserted within the disc, more or less connate. Ovary 4-5 celled, ovule solitary (?) erect. Capsule ligneous, globose, 3-5 celled, tubercled externally, dehiscence loculicidal; seeds arillate, albumrninous. Trees or shrubs with alternate,
imparipinnate leaves, mostly deciduous.
Several of the deciduous, pinnate leaved trees seen without leaf, flower or fruit, probably belong to this African genus. The following evergreen tree is included in it with great hesitation :Bersama (?) mossambicensis. (New species.) Vern. names-5, Tsukuhlumumbu; 6, Maritshima; 4 and 6, Morentima or Shimorentima (these names shared with
Blighia). Leaves pinnate, exstipulate, the pinnules sub opposite or alternate, elliptical or oblong-elliptical, pointed, usually oblique and tapering shortly at the base.
Inflorescence axillary to the upper leaves, about 3-flowered on a 1-2 c.m. peduncle; flowers almost sessile, 3 m.m. long, bracted; calyx with 5 triangular teeth; petals 5, imbricate; stamens io-i 2, outside a flat ring-disc, the filaments free and apparently equal (though no fully mature flowers were available for examination); anthers hairy; ovary pubescent, 4-5 celled, with almost sessile stigma. Fruit woody, tubercled outside, dehiscent, 4-5 celled, each cell containing 2 black seeds pendulous from a red aril rising from the base. I hesitate to make a new genus of this tree, but it does not appear to me to fit any described genus well. It has much resemblance to Trichilia, from which the free stamens and 4-5 celled ovary distinguish it ; from normal Bersama the 2-ovulled cells and the more numerous
stamens differ. Frequent throughout the Province, often as a shrub but sometimes as a very large tree. Sim 5204.
Ovules formed in closed ovaries. Calyx and corolla usually both present. Calyx-tube either free from, or adnate to, the ovary. Petals free; petals and stamens springing from the calyx-tube, either perigynous or epigynous.

Shrubs or climbers, often tindril-bearing. Flowers regular, apparently perfect. Calyx cup-shaped, entire or lobed. Petals 4-5, free except their points, which usually cohere, deciduous by each petal dehiscing at its base, the cap-like united points falling off together. Stamens opposite the petals, 4-5, free, hypogynous, inserted outside the disc which surrounds the ovary. Ovary ovoid, pointed, 2-celled; style short or absent; cells 2-ovuled. Berry fleshy, globose, 1-2 seeded, edible or astringent.
71. VITIS. Shrubs or climbers; leaves simple or digitately compound, branches herbaceous or ligneous, tindrils usually present. About So tropical African species are
described, neither of which have any forestal value, and many are forest weeds of the nature of monkey-ropes. A 3-foliate shrubby species (4, Ingwanhela; 6, Ruta) common in extra-tropical districts is used for making sieves from the bark; and the succulent stems of V. quadrangularis (4, Clemafin) when heated are applied to
cuts, &c.
SBersama (?) mossambicensis. (Sp. nov.) Plerumque frutex, sed aliquando arbor grandis. Foliis exstipulatis, pinnatis; foliolis sub-oppositis vel alternis, ellipticis vel oblongo-ellipticis, acutis, plerumque obliquis et basi abrupte contractis. Inflorescentiis in axillis foliorum superiorum, circiter trifloris, pedunculo 1-2 ; floribus fere sessilibus, bracteatis, 3 m.m. longis; calycis dentibus 5 triangularibus; petalis 5 imbricatis; staminibus o10-12, filamentis liberis et (vix maturis) aequilongis; antheris hirsutis; disco annulari piano inter stamina et ovarium ; ovario pubescente, 4-5 loculari ; stigmate sub-sessili.

85. ANACARDIUM. Flowers polygamous in large terminal panicles. Calyx-segments 5 ; petals 5; stamens about io, not all equal; ovary a free, sessile, i-seeded nut, with
an oblique style, changing to reniform as it advances. Fruit reniform, attached by one end to the much-enlarged, succulent, edible, oblong pedicel.
A. occidentale, Linn. Vern. names-i, Cashew; 2, Caju or Cajueiros; 4 to ii, Canjew. A spreading evergreen tree, originally introduced long ago from America;
widely distributed and protected by the natives; and now the most frequent tree in the Province in or near where cultivation is, or has been, practised. Many large areas of abandoned lands are almost pure open forests of this tree, and the natives never cut it down as it supplies both food and drink. Flowers polygamous; either pistillate only, with a somewhat reniform ovary and lateral style from the sinus; staminate only with about io stamens, of which one is long; or having both pistil and stamens, of which the former is conical subulate and abortive, and the latter all short except one. The so-called "fruit" is a swollen pedicel, 4-6 c.m. long, 4 c.m. diameter, forming the well-known succulent and edible article; the true fruit is the upper reniform portion usually known as the Cashew-nut, eaten roasted, and distilled into a strong spirit. Leaves obovate, rounded at the apex, narrowed below, petiolate, glabrous o10-15 c.m. long, 5-7 c.m. wide, prominently veined
below. Timber useful.

86. SCLEROCARYA. Flowers dicecious or polygamous. Sepals 4-5; petals 4-5. Male flower-stamens 14-18, inserted round a small fleshy disc, pistil rudimentary.
Female flower-stamens impotent, ovary 2-3 pointed, 2-3 celled, with i ovule in each cell. Drupe with a 2-3 celled stone, I seed in each cell. Seeds exalbuminous.
Leaves imparipinnate, alternate, glabrous.
S. caffra, Sond. Vern. names-2, Ocanheiras; 4, Okania and Helinga-maash; 5, 6, 7, 8, Tsula; so, Mtula or Motula; 13, Um-gamo; i6, Morula. A rounded, muchbranched, low, deciduous, dicecious tree, usually found in open grass or thorn country rather than in dense forest. Leaves 12-30 c.m. long, io0-i2 c.m. wide, simply pinnate ; leaflets about 4 pairs and a terminal one, all ovate, acute, oblique at the base, 3-5 c.m. long, 2-3 c.m. wide, with a 2 c.m. slender petiole. Male inflorescence in many-flowered racemes 6-9 c.m. long, clustered under the new leaves, mostly with 4 petals, 14-18 stamens and rudimentary pistil; female flowers 1-3 on peduncles 2-3 c.m. long, also clustered below the new leaves, and with 5 petals, impotent stamens, and ovary 2-3 pointed, 3-celled, with i ovule in each cell. Fruit elliptical, 3-4 c.m. long, containing one 3-pointed 2-3 celled bony nut, with I seed in each cell, the seed growing through an opening at the top of the cell, and the empty nut afterwards showing 2-3 holes at its apex like a palm seed. The thick oily cotyledons are edible and the fruit is used for the production of an intoxicating liquor.
The bark is used for water-buckets, for drums for peanuts, &c., and for boats.

87. HITZERIA. Unknown to me; described by Prof. Oliver as follows:-" Flowers moncecious. Calyx 4 (5)-lobed; segments oval, valvate and exceeding the petals in
bud. Petals 4 (5), inserted on the calyx, slightly imbricate. Stamens (of male flowers) 8, alternately shorter, inserted on the calyx; anthers oval-oblong; mucronate, versatile; ovary o. Female flower 5-merous. Stamens io, rudimentary; ovary 3-celled; style short; stigma peltate, 3-lobulate. Drupe tomentose, I-celled, s-seeded. Seed ascending with a minute inferior radicle and thick, fleshy, piano-convex cotyledons. Tree. Leaves clustered at the extremities, unequally pinnate,

with solitary ovule pendulous from a basal funicle. Styles 3, free or connate below; ovary of male flower abortive or absent. Drupe usually dry, with a coriaceous or ligneous putamen, i-seeded, exalbuminous. Many species, of which nearly half are South African, and of these a good few extend into the-southern forests of this Province. These are 3-foliate useless shrubs or shrublets, for which see Flora Capensis," I. 506, and Forest Flora of Cape Colony," page 192. Among the vern. names for these I noted the following, viz. :--4, Hlaba-kunkune; 6, Gandasendua; io, Anamaka and Siwawe; 15, Hlongoshan, Umhlanyoni and Pembet.
Of the i-foliate species which constitute the sub-genus Anaphrenium, the following occur :R. longifolia, Sond. A large tree found throughout the Province, as also in Cape Colony and Natal. Leaves alternate, oblong or elliptical, tapering to each end,
undulate, o10-15 c.m. long, 3-4 c.m. wide, petioled, glabrous, green above, pale below. Panicles terminal on main and side branches, large or small, canescent.
Drupe oblique, I-I'5 c.m. long, almost black. This and the 2 following species are not separated in native opinion, and the following names are used for the 3,
viz. :-4, isi-nungu-mafe; 5, 6, Sassa, Satsa or Intsatsa; io, Na-kadi, Mkakambi, or Mikatanguo; 12, isi-fuce or isi-fika; 13, Umkomiso; 15, Siete.
R. insignis, Delile. A smaller tree than the last, often only 3-5 metres high; leaves 9-o0 c.m. long, 2 c.m. wide, glabrous above, silvery below, usually ternate. Panicles
pubescent. Abundant Maputa to M'Chopes, present but less frequent on the Zambesi and northward. Too near R. mucronifolia, Sond.
R. Salicina, Sond. Small tree 3-5 metres high; leaves oblong, mucronate, hairy on the upper surface, pubescent and somewhat silvery below, alternate, sub-opposite and
ternate. On the top of the Lebombos near Estatuene.
In the forests of Magenja da Costa coppice shoots were found where the roads had been cut, which had elliptical leaves 12-15 c.m. long, 4-6 c.m. wide, green and softly pubescent on both surfaces, which surroundings indicated to be coppices of Rhus longifolia. If so, the 3 species here mentioned should be regarded as
forms rather than species.
83. SORINDEIA. Flowers small, polygamous or dicecious, in terminal or axillary panicles. Leaves pinnate. "Petals valvate or sub-valvate. Ovule suspended near middle
of cell." As the only species found in the Province is included in the genus with doubt by Prof. Oliver in "Flora of Tropical Africa," and differs generically from the other species, further characters are here omitted and given only for that species, of which my material is insufficient to constitute the new genus which will be
required when complete material is obtainable.
S. (?) trimera, Oliv. Vern. name-io, Msamba. A very large glabrous tree, growing near streams in Magenja da Costa and Nhamacurra. Leaves alternate, 22-30 c.m.
long, imparipinnate; leaflets about 4 opposite pairs and terminal one; 5-io c.m. long, 5 c.m. wide, elliptical, bluntly pointed, entire, firm, glabrous, with stout petiole 5-10io m.m. long and pronounced midrib. Panicle terminal 8-20 c.m. long, many-flowered, seen by me in fruit only. Fruit 3 c.m. long, 2 c.m. diameter, ovate,
green, seated in the persistent 3-lobed calyx, within which and under the fruit 3 oblong petals and 6 filaments often remain under a membranous disc-ring. The filaments do not show whether all are stamens or 3 staminodia. Fruit with hard bony putamen, 3-celled, usually only i cell fertile, i-seeded, the seed nearly flat, pendulous from near the top of the axile placenta, exalbuminous. Juice of the fruit resinous, exceedingly viscid, and smells strongly of turpentine. Juice of stem watery or somewhat milky, flowing freely and drying to a gum used for caulking boats. Formerly recorded only from West Africa. This will probably prove a valuable timber tree, and is often 10ioo to 150 c.m. diameter. The 3-celled fruit, 3-merous flowers and opposite leaflets all indicate that this tree is out of place in
this genus.

84. MANGIFERA. Flowers polygamous or dicecious. Calyx 5-lobed; petals 5, imbricate in aestivation; stamens by abortion usually i ; ovary free, sessile, i-celled; drupe
i-seeded, more or less edible, with a fibrous fleshy mesocarp and a large bony putamen. Leaves simple, entire, alternate.
M. indica, Linn. Vern. names-i, Mango; 2, Manguiera. A large glabrous tree, having many more or less permanent varieties differing among themselves in foliage
and fruit; leaves oblong-lanceolate or wider, 12-24 c.m. long, 3-6 c.m. wide, acute, petioled. Panicle terminal, many-flowered, 10-30 c.m. long. Fruit obliquely
oblong, ovoid, or curved 8-i6 c.m. long, 4-8 c.m. wide, somewhat compressed, and variable in regard to colour, flavour, and amount of fibre, but including varieties which are first-rate dessert fruits. Male flower-calyx-segments 5 ; petals 5 ; stamen i among incurved glands. Female flower-no stamens; ovary 5-lobed, with central subulate style. Probably originally introduced from Asia, but now widely dispersed throughout the tropical forests, and usually the largest trees in these
forests, often up to i metres diameter, and used to make the largest dug-out boats (Mandea).

Stamens usually io, sometimes fewer or many, hypogynous or perigynous, free or variously connate. Pistil superior, consisting of one i-celled carpel, usually flattened, with I or more axile ovules attached to its ventral suture. Style terminal. Fruit usually a legume, i or several-seeded; seeds exalbuminous. Leaves usually pinnate or 1-3 foliate, usually alternate, and stipulate. A vast Family and including trees, shrubs and herbs, and represented almost everywhere, usually taking a high place with regard to the number of species in any flora. The trees are mostly tropical or sub-tropical, and the tree-flora of this Province may be described as a Leguminous one, these trees taking a prominent place everywhere, and forming in places large almost pure forests of Acacias in the south, of Brachystegia in the M'Chopes, and of Pterocarpus in the north. Of its 400 genera 83 are South African and 141 Tropical African, 48 of these being common to both, only a few of these, however, being arborescent. The Family includes such a variety of useful plants that only the more important can be enumerated here. Among food materials for man or stock are Peas, Beans, Lentils, Carobs, Tamarinds, Clover, Lucerne, 'Fares, &c. Senna and others are medicinal; the bark of many species of Acacia is used in tanning; gums are yielded by Acacia and several other genera; Indigo, Camwood and Logwood are important dyes, and the number of active poisons is very considerable. Valuable timbers, usually with black or dark heartwood, occur in most warm countries, and this Province is well provided with such.
The Family divides more or less naturally into 3 Sub-Families, viz. :i. Papilionaceas. Stamens lo (many in Swartzia and Cordyla). Corolla irregular, papilionaceous; petals imbricate, the upper exterior.
2. Casalpinia. Stamens io or fewer. Corolla sub-regular, imbricate, not papilionaceous, the upper petal within the others.
3. Mimoseae. Flowers minute in dense heads or spikes. Corolla regular, valvate in aestivation. Stamens io or many. Leaves 2-pinnate.
Stamens io (many in Swartzia and Cordyla), free or variously connate. Corolla irregular, usually papilionaceous; petals 5, free or somewhat adnate to the staminal tube, usually arranged as i standard, outside in bud, 2 wzing-petals, and 2 lower petals, frequently coherent by their lower edges and forming the keel. Leaves simple, 3-foliate or imparipinnate (in our trees).

Synoptical and Specific Descriptions. 4I
90. INDIGOFERA. Shrubs or shrublets having usually imparipinnate but sometimes 3-foliate or i-foliate leaves, and axillary few or many-flowered racemes or clusters of white, rosy, or purple flowers. Calyx small, green, 5-toothed. Standard roundish, reflexed; wings narrow, partly adherent to the keel, which has a wart or spur on each side near the base; upper stamen free, the other 9 connate; connective with a glandular point. Ovary sessile, usually many-ovuled, sometimes 2 or fewovuled. Pod usually linear, terete or more or less flattened, dehiscent, the seeds often separated by septa. Pubescence often strigose. A large tropical and subtropical genus of herbaceous or woody undershrubs, never of timber size, but of interest as the source of indigo, which is obtained from the macerated leaves of several (or many) species. Among those which yield commercial indigo are I. tinctoria, I. anil, I. hirsuta, I. endecaphylla, and I. arrecta, all of which occur in the Province, but the presence of colour is not known to the natives, who have no use for these plants. In the "Flora of Tropical Africa" the two first-mentioned above are spoken of as cultivated; this does not apply here however, for I did not see a single plant of any Indigofera under cultivation. The native names appear to be more or less generic, and are, 6, Nkaromeba; io, Sa-wayo. There has of late been a demand from India for seed of colour-yielding Indigoferae, and the culture of plants for seed may be worth attention even though the cost of labour may prevent actual indigo extraction locally. See Forest Flora of Cape Colony,"
199, Plate LIV. fig. 3.
91. DALBERGIA. Trees, shrubs or climbers, often spine-bearing, and having alternate imparipinnate leaves with alternate or sub-opposite leaflets, and corymbose axillary or terminal panicles of small white or yellow flowers. Calyx 5-toothed, the teeth unequal, the lower one longest. Petals clawed, the side ones narrow ; the keel petals connate at the point, enclosed in the standard. Stamens io, connate, the tube having i or 2 slits, or i stamen absent. Ovary stalked, 1-3 ovuled. Pod compressed, oblong, usually i-seeded, not winged, indehiscent. Many tropical species, mostly climbing forest weeds, but various Indian and Brazilian species yield valuable timbers, usually having black or purple heartwood; the best known is the Sissoo tree (D. Sissoo, Rox.), now extensively cultivated in India. Of the 5 species recorded from this Province 4 are climbing shrubs, often monkey ropes, but in the absence of support forming semi-erect shrubs, to which the names, 6, Tiriane; io, Sambelemu, are given. A similar rambling shrub is D. obovata, E. Mey, common in Lourenzo Marques and M'Chopes. See Forest Flora of Cape Colony,"
199, Plate LI. fig. 2. An erect unarmed shrub 3-5 metres high in the northern forests, and constantly bearing fruit-like galls, but not seen in flower or fruit, is
believed to be a Dalbergia, and is known as, to, Munyenye.
D. melanoxylon, Guill. & Perr., has the reputation of being one of the valuable timbers of this Province, and is known as, i, Ebony; 2, Grenadilha; but though
constantly looked for I found nothing to answer its description, and doubt its presence in any quantity. It is thus described in "Flora of Tropical Africa" :-"A copiously branched bush or small tree, 15-20 feet high, with stout woody glabrous branches and long sharp woody spines. Petioles under -in., glabrous; leaflets 9-13, short stalked, oblong or obovate, in. long, both ends rounded, often emarginate, sub-coriaceous, both sides glabrous, veins beneath raised. Flowers in copious terminal and axillary panicles, the latter equalling or shorter than the leaves. Pedicels a line long, slender, glabrous, bracteolate. Calyx 2 lines deep, glabrous, upper teeth deltoid, the lowest lanceolate. Corolla yellow, slightly exceeding the calyx. Pod --2 in. long, -in. broad, blunt or sub-acute, with a long pedicel, the valves glabrous and membranous. Seeds 1-4. Mozambique, Dr. Peters; Zambesi-land, Dr. Kirk!

ground. Leaves pinnately 3-foliate, usually deciduous, with a gland at the bare of each leaflet. Stipules small, free. Flowers in stalked, many-flowered racemes, very showy, scarlet, red, yellow, or white, often produced before the leaves. Calyx entire or split; with or without 2 or more lobes. Standard large, flat and reflexed, or infolded and elongated, much larger than the narrow wings or the shorter connate or free keel petals. Stamens connate below only, with a split tube and having the upper one partly or quite free. Ovary stalked, ovules numerous. Pod stalked, narrowed at both ends and between the seeds, dehiscent. Seeds
oval, red, with a black hilum. A widely dispersed, usually tropical order.
E. tomentosa, R. Br. Vern. names-i3, Umsinsi (Pondoland), Um-kwaba-kwaba (Natal). A tree of stiff habit, seldom over 7 metres high, and with stem diameter up
to 45 c.m. Stem bare, rugged, with leaves at the top only. Leaves very large, the terminal symmetrical, 6-9 inches wide, 4-6 inches long, the lateral oblique and rather smaller. Spike many-flowered, short ; flowers dull crimson, not showy. Calyx split down one side, and having 5 slender segments. Pod 6 inches long, not prickly. Whole plant more or less tomentose. It is not easily killed by fire and consequently stands where most other kinds have been burned out, but it is never
found in dense bush. Timber soft, light, useless except for brake-blocks. Recorded from Zambesi-land. "Natal Plants," 384, 385.

In the "Flora of Tropical Africa P. angolensis is included as a synonym, and concerning this Miss L. S. Gibbs says :' "P. angolensis A.D.C. which has often been quoted as a synonym of P. erinaceus, Lam., is easily distinguished by the larger flowers and much larger fruit, which has more bristles in the centre and a broader wing." All the trees seen throughout Mozambique Province appeared to be alike, and with less variation than most species. Present though not abundant throughout the extra-tropical parts of the Province, abundant through the tropical districts and in some places as in the Robe Forest, near Arenga, Magenja da Costa forming almost pure forest. A valuable and durable timber, found in great abundance, and certainly the most valuable asset the Province has in its tropical forests. It extends into Natal, Swaziland, the Transvaal, and to the West Coast, and (including P. angolensis) from the coast to the Matopos.

Stamens all free, one standing separate. Ovary pubescent with about 6 ovules. Pod dehiscent, 5-7 c.m. long, flat, several-seeded., Never large, but a valuable timber and in demand. Frequent in Maputa and Marracuene; especially toward the Lebombos, less common near Lourenzo Marques, and not noticed
north of the Limpopo, though being deciduous and leafless while I was there it may have been overlooked. Occurs also in the Transvaal and Rhodesia.

Ovary somewhat stalked, with several ovules. Pod woody, several-seeded, sometimes wide on the upper side.
L. laxiflorus, Guill. & Perr. Vern. name-4 and s15, Panda. A small tree 5-so metres high, with straight stem 30-45 c.m. diameter, grey bark, and glaucous more
or less deciduous foliage. Leaves pinnate, 1-3-5 foliate, with peduncle 2-5 c.m. long, rachis 2-stipellate below the upper leaflet and at each pair of leaflets ; leaflets varying much with age and position front widely lanceolate, acute, 3-5 c.m. long, to ovate or obovate, rounded or bluntly pointed, 8-15 c.m. long, 4-8 c.m. wide, glabrous and finally subcoriaceous. Panicles terminal, o10-15 c.m. long, spreading, many flowered; flowers light blue, sweetly scented; side and lower petals eared; stamens connate I their length, upper one partly free. Pod flat, 5-1o c.m. long, 2 cm. wide, with a thick upper suture, 1-3 seeded; seeds reniform, flat, 1-5 c.m.
long. This looks a promising tree, but is practically a forest weed since it has no value. The timber is useless and not durable, and will not burn ; the tree reproduces itself freely from seed, and also every cut root grows and stumps are difficult to kill. Although the flowers are rather pretty, Wistaria-like, this is a tree which it is well to be rid of. Abundant in Lourenzo Marques, Maputa and Marracuene; not noticed north of the Limpopo, but probably present and deciduous during my visit, as it is recorded from Zambesi-land, Kirk!

Planted from stem cuttings along the roads as a shade tree at Quisico; frequent in M'Chopes and Inhambane (extra-tropical), and abundant in the forests of Quelimane, Magenja da Costa and Nhamacurra (tropical). This and various other trees have the name Pao-ferro (= ironwood) applied to their
timber on account of its hardness. Sim 5382.

104. SWARTZIA. An American genus with only one African species.
S. madagascariensis, Desv. Vern. name-io, Naquada. A tree 10-20 metres high, with erect, nearly white stem, 20-40 c.m. diameter; imparipinnate leaves, few
flowered racemes, and long terete pods which easily identify the tree. Leaves alternate, 16-20 c.m. long, io c.m. wide, with 9-I 1-13 leaflets; the terminal one 5-7 c.m. long, 2'5-4 c.m. wide, obovate; the others elliptical, minutely mucronate, 4-5 c.m. long, 2'5 c.m. wide, with petioles 3 m.m. long. Youngest wood, rachis,
petioles and veins densely but finely silky-pubescent; under surface of leaf sparingly so. Pod 15-30 c.m. long, indehiscent, terete or very bluntly 4-sided, 15-20 m.m. diameter, rounded and mucronate at the point, with the seeds in a central cell, having an empty cell on each side and a glabrous brown leathery coat, somewhat fleshy inside.
This and several other trees yield very hard dark timber known as Pau-ferro, (=iron-wood) and probably on this account I found natives confuse this and the dissimilar Lonchocarpus mossambicensis, some giving the names Pangira and Naquada to either. The Portuguese name Scopira belongs to one or both of
these. Abundant in most of the forests north of the Zambesi; not seen in the extra-tropical districts. Recorded from most other parts of Tropical Africa.

peduncle, leathery indehiscent, 1-8 seeded, the seeds lying across the fruit, and varying very much in size and form. The timber which is light and soft is that used for the construction of native pianos (6, Marimba, to, Mangwela) and also for native drums. Nowhere abundant, but not uncommon throughout the Province
present also in Nile-land and Senegambia.

o8. CAESALPINIA. Represented in this Province by only one species C. Bonducella, Roxb., which being barely of shrub size, and of no practical use, is hardly worth
mention here. It has large 2-pinnate leaves 30-45 c.m. long; recurved prickles on the stem, rachis and inflorescence; many flowered bracted racemes; nearly regular, yellow flowers; and oblong, prickly, somewhat compressed pods 5-7 c.m. long, 3-4 c.m. wide. It is frequent near the coast or tidal rivers throughout the
Province, and children use the pods as rattles.
C. pulcherrima, Sw. (= Poinciana pulcherrima, L.), is common in cultivation and is the street tree of Quelimane (where it is called Acacia), but is hardly naturalised
anywhere. Its beautiful foliage, scarlet flowers, flat crown and long pods make it a marked feature, but somehow its beauty is not appreciated where it grows easily.
og. CASSIA. A very large genus of trees, shrubs and herbs, represented in this Province by io or 12 species of useless half-ligneous shrubs or shrublets of no importance
except such as is attached to them in native medicine and superstition. They have paripinnate leaves, and axillary racemes, clusters, solitary flowers, or terminal panicles of yellow flowers. Calyx deeply 5-parted, the segments often unequal, imbricate. Petals 5, hardly equal; stamens 5, 7, io, in the latter case the upper 3 often smaller and effete, all basifixed and dehiscing by terminal pores. Ovary elongate; ovules many; legume terete or flattened, many-seeded, dehiscent or

48 Forest Flora of Portuguese East Africa.
iio. BAUHINIA. Trees or climbing shrubs easily recognised by the leaves which appear to be simple and 2-lobed, but are formed of 2 leaflets connate along their upper edges. Flowers are axillary or terminal on i, or few-flowered or racemose peduncles. Calyx-tube various, its limb either of 5 free segments, or split at one side only and reflexed as a single spathe. Petals 5, clawed, nearly equal, white, red, or purplish. Stamens io or fewer, perfect or some imperfect, with free or almost free slender unequal filaments, and versatile anthers dehiscing longitudinally. Ovary stalked, several or many-ovuled. Pod flat, woody, dehiscent or indehiscent, several-seeded; seeds flattened, albuminous. A large tropical genus, widely dispersed. i tree, T shrub, and 3 sub-scandent shrubs are included in the Flora of Tropical Africa," as from Mozambique district. The tree I found in abundance in the tropical districts, together with what appeared to be only 2 species of straggling shrubs, all passing under the one name Masi-kesi; in the extra-tropical districts only r species was observed, a small straggling shrub used for cordage and known as, 6, Batela; 15, Umtelem, in the M'Chopes and Lebombo, but as all except the tree were without flowers or fruit, they were not in condition
for identification.
B. reticulata, D).C. Vern. name-ro, ii, Masikesi. A medium-sized or small tree, seldom over 15 metres high and 30 c.m. diameter of stem, usually rather crooked
and gnarled, and though of good nearly black timber, seldom of size and form to be of use. Leaf 8-12 c.m. long, 12-18 c.m. wide, glabrous above, velvety below, about 9-veined. Young growth rusty-tomentose. Petiole and inflorescence tomentose. Raceme terminal or opposite a leaf, branched. Calyx-lobes free, or sometimes cohering. Petals white or nearly so, obovate and clawed, equal, pubescent outside. Stamens io. Pod 8-20 c.m. long, 2-5-5 c.m. wide, with a 3 c.m.
gynophore, a long point, and a dense coat of dark velvet. Seeds several. "The bark yields a tough fibre; it is also astringent and used in Medicine." Abundant
from the Zambesi northward, showing preference for open glades, though sometimes found in thick forest.
PLATE XLIII. I, Fruiting branch ; 2, Medium-sized pod ; 3, Tree, general aspect, reduced.
III. BERLINIA. Unarmed trees, with abruptly pinnate leaves; panicled racemes of handsome white flowers; and long flat coriaceous dehiscent legumes. Sepals 5; petals
5, unequal; Stamens io, all perfect, connate at the base, except one. Ovary shortly stalked; ovules 6-8; buds enclosed between a pair of bracteoles. Several
species, all Tropical African.
B. acuminata, Sol. Unknown to me, but recorded with a doubt from Rovuma in "Flora of Tropical Africa." It is described as a tree 7-20 metres high, almost
glabrous, with simply pinnate leaves, 3-6 pairs of oval leaflets 8-24 c.m. long, 4-12 c.m. wide. Flowers in terminal simple or usually corymbosely panicled hoary racemes; posterior petal ample, 4-8 c.m. long, clawed, with cristate margin ; other petals small, linear, dilated or auricled below. Legume 24-30 c.m. long, 5 c.m.
wide, flat, with the ventral suture thickened and laterally ridged.
112. AFZELIA. Trees with abruptly pinnate leaves, terminal racemes of curiously irregular flowers, and thick woody oblong pods containing several black seeds, each set in
a scarlet or yellow aril. Only one species is known to belong to this Province.
A. quanzensis, Welw. Vern. names-i, Mahogany; 2, Ompow; 4, 15, Hlafuta, or Chaputa; (Benguelle? at Manhica); 5, 6, 7, 8, Inchenu, Insena, Sina, or Xina;
io, Musacosse, or Momba periwede; i, Mugoberere. A medium sized or large tree in accordance with locality, I5-20 metres high, 40-60 c.m. diameter of stem, with a good bole and a spreading gnarled crown, perhaps regularly deciduous, but the trees vary in their leafless season. Leaves glabrous, dark green, shining, paler below, 20-30 cm. long, with about 4 pairs of leaflets which are elliptical, rounded or bluntly pointed at the apex, shortly petiolulate, undulate and with a slender rachis, swollen at the base. Flowers in racenimes, terminal on short leafy branches, 6- 2 flowered. Sepals 4, 1'5-2 c.m. long, convex, finely canescent, the upper smaller. Vexillumn 4 c.m. long, narrow below, widening upward and with a sharply widened lip 2'5 c.m. wide. Other petals absent. Stamens 7, of which 3 are longer than the others. Lower 2 occasionally but not regularly transformed into a club-shaped petaloid form. Pistil longer than the stamens, 4-5 c.m. long.
Pod 8-20 c.m. long, 4-5 c.m. wide, 12-20 m.m. thick, dehiscent, firmly woody, 3-8 seeded, the seeds black, each set in a cavity in the shell, and having a scarlet cupshaped aril at the base. Occurs throughout the Province, nowhere in great abundance, but always forming a factor in forestal calculations. Yields a valuable
timber, and the seeds form a marketable commodity as a curiosity. A. Petersiana, Klotzsch in Peters' Mossamb. Bot. 19.

On the Lebombo mountains near Estatuene what appears to be another species of Afzelia occurs as a shrub 1-2 metres high with a large rootstock and more rounded
leaflets (= 15, Ndlebe-in-hlovu), and in the kloofs below another bush 3-4 metres high (4-15 Umseq), but neither of these were found in flower or fruit.

13. BRACHYSTEGIA. Unarmed trees with abruptly pinnate leaves, flowers rather small in terminal simple spicate dense racemes or axillary paniculate confluent glomerules. Flowers in bud enclosed by 2 bracteoles. Calyx reduced to several minute scales; petals absent; stamens 10-13; filaments somewhat connate at the base; ovary 5-8 ovulate; pod oblong, compressed, dehiscent, woody, with a wide ventral suture. Seeds several, compressed, exalbuminous. A Tropical African genus, having fibrous bark largely used by the natives for water-boxes, drums, &c., and when beaten out and chewed it is the only cloth available in many places; it also contains tannin worth commercial attention. By the descriptions I cannot separate B. appendiculata, Benth., which is recorded from the Northern districts
by Drs. Miller and Kirk from B. spicaeformis.
B. spicaeformis, Benth. Vern. names-5, 6, Tzontzo, Tondo; 7, 8, M-tamba; io, Marotta, ii, Macarara. The timber is known with several other timbers as,
2, Pau-ferro (= ironwood), and the fibre as (2) Casca-pano. A tree 10-15 metres high, 20-40 c.m. stem diameter, with a rounded spreading crown where space allows. Young growth minutely pubescent, soon glabrous. Rachis to c.m. long; leaflets usually 4 pairs, 4-5 c.m. long, shortly petiolate or almost sessile,
obliquely ovate, rounded at the point and often with about 3 veins from the base. Stipules linear, caducous. Leaves on coppice shoots twice as large, sometimes acute, and with falcate stipules 15 m.m. long, sometimes with a transverse reniform leafy appendage or auricle at the base of each. Flowers subsessile in terminal, simple, very dense, feruginous, spiciform, ovoid or oblong ovoid racemes I or 2 inches long, much exceeded by the leaves. Involucral bracteoles obovate or elliptical J-A inch long. Perianth usually reduced to 2 linear or lanceolate ciliate scales about one line in length, alternating with the bracteoles; occasionally a few additional minute scales are present. Stamens 10- 13, unequally and distinctly monadelphous, glabrous. Ovary laxly or substrigose-pilose on a stipes of its own length; ovules 7-8." Pod 15 c.m. long, firmly woody, dehiscent, at first densely velvety, sharply and obliquely pointed, compressed, sharp one side, but 7-1o m.m.
wide, with a more hardened and furrowed edge on the other. Seed flat, 2 c.m. long, oblong, exalbuminous. Though not a large tree this is perhaps the most important tree in the Province under its present circumstances; the natives in the northern districts make all their cloth from the bark of this and other species of this genus; the natives of M'Chopes make all their water-baskets, beer vessels, grain drums and cordage from its bark, and only use another tree for cloth because that is more easily prepared; throughout the Province, north of the Limpopo, they use the bark of this only for making cradles, coffins and beehives, and the timber is hard and durable and takes a part in all domestic woodwork construction. The water-basket, an implement of immense utility in the sandy districts where water is only obtainable at distances of several miles, is made by ringing the tree at two places, 4-5 feet apart, cutting down one side and removing the piece of bark intact, the two incurved sides are kept apart and in place by skewers, the ends are doubled up and the met edges sewn together at the corners, and the cross ends sewn to the skewer nearest to each, the sewing being done with fibre made of itself. These baskets last well and do not leak, and though the removal of the bark kills the tree, that is of little consequence where trees are abundant. I saw water brought up out of a well 20 metres deep by a half-inch rope of the twisted bark of the branches, which is also used for hinges and wherever fibre can be used, and a piece subjected to a strain of 400 lbs. did not break, but, of course, stretched out considerably. The bark also contains about 18 % of tannin, and as there is a vast quantity of it available, I consider that an extract might be made on the spot and shipped out with considerable profit, though I fear the shipment of the bark itself cannot be done profitably. The seed is also said to be edible. The M'Chopes country is in many places almost a pure forest of this, especially where extensive cultivation was abandoned after Gungunhamas raid, 12 years ago, and where now a dense forest of seedling trees of this species, 6-8 metres high and 15 c.m. diameter, is already in possession and ready for first thinning. The utilization of this bark is a forest problem of equal importance with the utilization of all the timber in the Province, and well deserves skilled management, and may some day bring a large revenue. The tree is abundant from the Limpopo to Inhambane, and frequent in the forests further north. It was not noticed in Lourenzo Marques district, and if present at all is scarce there. The large beans have not so far been experimented on, but will, I think, be found to contain a lot of tannin, and are produced in enormous quantities and weigh well. The regrowth is excellent everywhere, and the tree is inclined to monopolise
suitable districts. Found also in Zanzibar and Angola.

This is included as a synonym under T. Hornemannianum, Hayne, in the Flora of Tropical Africa," but is quite distinct from the tree cultivated under that name, in having shorter, wider leaflets, always somewhat glaucous, often canescent, and in the presence of spines. T. Hornemannianum is credited with yielding
part if not all of the Copal of East Tropical Africa.

pinna each with about 12 pairs of oblong leaflets. Pod 12-15 c.m. long, 3 c.m. wide, glabrous, many-seeded. A forest weed, making such a dense mass as to kill
the trees on which it hangs, and most difficult for a person to get through if near the ground. Frequent in the extra-tropical parts of the Province.
121. TETRAPLEURA. Trees with alternate, bi-pinnate, glabrous leaves, spicate inflorescence, stamens io, anthers with an apical gland and 4-sided indehiscent legumes.
Several species are West African, as is also the following:T. obtusangula, Welw. M.S.S. ("Flora of Tropical Africa," II,, 331). Vern. name-io, Mseriale. An erect tree 10-15 metres high, with stem 30-45 c.m. diameter,

122. PROSOPIS. Trees with hi-pinnate leaves, spicate inflorescence, and subterete indehiscent pods with septa between the seeds. Mostly American; the pods of some
used as cattle-feed.
P. (?) Kirkii, Oliv. Unknown to me; described in "Flora of Tropical Africa" as "A large tree; extremities unarmed, glabrous or obsolete-puberulous, slightly furrowed
when dry, with pale ashen bark. Pinna 6-7 jugate, with a sessile gland between the pinna, rachis puberulous above. Leaflets 10-17 jugate, subsessile, oblong, obtuse, minutely pubescent, 1 inch long, i line, more or less broad. Flowers in solitary axillary spikes 4-6 in. long (apparently insect-punctured in our specimens). Legume 5-8 in. long, i in. broad, flat, coriaceous, circinate, with a short hooked apiculus. Seeds compressed, ovate, with a shining testa and

Kirkii, Benth (in Trans. Linn. Soc. XXX., 1875, 383), as Tropical African. The former is said in Fl. Trop. Afr. to he from Delagoa Bay
and to be "nearly allied to D. nutans, differing in the fewer pinned of the leaves and one or two other characters of doubtful constancy," while of the latter I have no information.]
124. ACACIA. Trees, shrubs or climbers, usually prickly or spine-bearing, having bi-pinnate leaves and clusters or spikes of small yellow, often polygamous flowers, either axillary or arranged in terminal panicles. Calyx-tube very short, or sepals free. Petals 5 or fewer, more or less connate. Stamens numerous, free. Ovary several or many-ovuled. Pod compressed or flat, dehiscent or indehiscent. A vast genus, present in most warm countries, but most numerously represented in species in Africa and Australia. The bark and pods of many species are rich in tannin; others yield gums, while from various species valuable firewood and timber are obtained. The Australian "Black Wattle" (a decurrens) is now largely cultivated in Cape Colony and Natal for its bark and timber. In several Australian species
the pinned and leaflets are suppressed, and the main rachis modified into a leaf-like phyllode.
A. albida, Delile. Vern. names-4, Newapf, and Bolela. A large tree, r5-25 metres high and with stem up to 6o c.m. diameter. Spines in pairs, stipular, straight, stout
below, 1-3 c.m. long. Foliage and bark light grey, leaves 7 c.m. long, pinned 4-5 pairs, leaflets 8-12 pairs; leaflets oblong, 5 m.m. long, I15 m.m. wide, ultimately
glabrous. Inflorescence spicate; spikes 7 c.m. long, axillary, single, or 2 together on short branchlet; flowers very light yellow or nearly white. Petals free nearly to the base, much longer than the calyx. Pods Io-12 c.m. long, 2'5 c.m. wide, flat but much twisted and bent, mucronate at the rounded apex; base oblique; peduncle 1-2 c.m. long. Bark light grey, woody or corky, with a general smooth appearance; timber grey, light, coarse-grained, fit for fuel only, and not good for that. Seedlings canescent or light grey puberulous, very much branched horizontally, and set with stipular straight sharp prickles 1-2 c.m. long. Frequent at
Umbelusi and throughout the alluvial deposits in the thorn-veld south of the Limpopo (extra-tropical); less common in Zambesia.
PLATE XXXIV. I, Branch ; 2, Pods ; 3, Spike ; 4, Flower, x 5 ; 6, Tree, general aspect (much reduced). Prof. Oliver (Fl. Trop. Afr.) doubtfully refers to this the A. mossambicensis of Bolle (Peters' Mossamb. Bot. 1-5) with the remark-" I do not observe any character in the published description by which it differs, excepting in the absence of spines. This however occurs occasionally in A albida."
A. nigrescens, Oliv. Vern. names-3, Knopjesdoorn ; 4, Mkaia. A glabrous tree 6-15 metres high, with straight stem 20-30 c.m. diameter; thorns in pairs, stipular,
10-12 m.m. long, hooked, always present, growing with age into knobs 3 c.m. deep, each with the sharp hooked thorn on top. Leaves glaucous, 5-8 c.m. long; rachis with one gland near the base; pinne usually 3 pairs; leaflets I pair on each, I'5-2 c.m. long, i c.m. wide, very oblique (or on coppice shoots 2'5 c.m. long and wide and less oblique). Inflorescence spicate. Spikes 5-8 c.m. long, axillary, or 3-4 together on special short branches. Flowers numerous, light yellow. Pod 7-1o c.m. long, 2 c.m. wide, flat, with I c.m. point; seed I-5 c.m. wide, flat. This differs from the western A. detinens, which is very similar in foliage, in its spicate
inflorescence. This tree covers large stretches of country in Maputa, Lourenzo Marques, Marracuene. and part of Gaza, usually as almost pure open forest with bare stems and grass underneath, forming splendid cover and grazing for game and stock. The tree is the most valuable forestal asset in the southern part of the Province, having a valuable durable dark hardwood which has been in demand for Transvaal mining purposes since the railway was opened through; on this account the tree has been almost cut out in so far as it is easily obtainable near the main line of railway, but a very large quantity still remains along the Swaziland railway and in the back country, which may assist to get development lines put down there at some future time. Meantime the Government has issued a proclamation
prohibiting the felling of this kind for the present; a wise step until it is in a position to collect license fees, or royalty, upon the timber so used.
The tree must have an unusual power of withstanding fire, for the grass is burned through the whole district every year, and I presume this burning is the cause why other species are not present. It seems to do best upon flat dry alluvial plains, and is absent from moist spots or river-sides. A variety has been separated under the name A. nigrescens, var pallens, Benth., and has since been raised to specific rank, as A. pallens, Rolfe; what its distinguishing characters are I have not learned, but Mr. J.

Burtt-Davy, in his "Notes on Some Transvaal Trees and Shrubs,"' says:-"Acacia pallens, Rolfe (A nigrescens var. pallens, Benth.) The type specimens, both of A. nigrescens and of var. pa//lens, are from' Zambesia, and in each case they are very incomplete. Additional material from the Transvaal enables Rolfe to separate the latter as a distinct species to which all our material so far collected appears to belong. I have incomplete winter specimens from Topsi, Bechuanaland, which may belong to A. nigrescens, but it is impossible to say definitely until foliage has been collected from the same locality. This is one of our most important timber trees, and is largely cut for mine-props under the name Knopjies-doorn or um-kai. The prickles persist for many years on the main trunk, and branches, effectually arming the tree, though to what advantage is not evident. The type of 'var. pa//lens' is from opposite Pita, near Senna, Zambesia, April, i86o, Kirk, 201, a tree 30 feet, very hard heavy wood, used for clubs." I did not find this species in Zambesia, but may not have been far enough up-country for it, and in the thorn-veld of the south I saw only one form, except in so far as differences occur through vigorous or poor growth, coppice shoots, &c.

A, Welwitschii, Oliv. Vern. names-3, Aapjesdoorn; 4, Mkaia. A glabrous tree 5-1o metres high, 20-30 c.m. diameter of stem. Thorns in pairs, apparently stipular,
always present, i-i"5 c.m. long, hooked, stout. Leaves 7-8 c.m. long; pinned 3-4 pairs; leaflets 5-7 pairs, lax, 7 m.m. long, 4 m.m. wide, elliptical; rachis with a
gland below the lowest pinna. Inflorescence spicate; spike 5 c.m. long, axillary, or panicled at the end of a branch. Pod 10-12 c.m. long, 2 c.m. wide, rounded at the base, rounded and bluntly pointed at the apex, nearly flat, about 6-seeded, very shortly stalked. Seeds oblong, i c.m. long. Frequent in the thorn-veld, mixed with A. nigrescens, and enjoying the same native name and reputation for its timber, which also is used in mining. About Machava the tree seems more vigorous than further inland, and has frequently up to 7 pairs of pinne. It is recorded from Zambesi, below Tete, but I did not find it in the lower Zambesian districts.
Miss Gibbs, in recording it from Victoria Falls, where it is the only Acacia mentioned by her, says:--" Large tree, with flat crown. Flowers pink, with pink rachis to raceme." Although hardly in flower during my visit I believe the flowers to be yellow.

A. glaucophylla, Steud. Vern. name-io, Egamosena, which name is used for several thorny Acacias. A large tree in the forests of Magenja da Costa, without
branches below. Younger parts finely pubescent, older parts glabrous. Spines in pairs, apparently stipular, 5 m.m. long, recurved. Leaves with about 6 pairs of pinne, each with about 12-16 pairs of leaflets. Leaflets about i c.m. long, 2 m.m. wide, very oblique at the base, and with the vein near the upper margin.
Inflorescence spicate; spikes axillary, 4-5 c.m. long. Pods variable in outline, usually o10-12 c.m. long, 2-2"5 c.m. wide, rounded and suddenly pointed, sometimes
more narrow or with a waved margin, about 6-seeded, flat, coriaceous, reticulated, glabrous when mature. Seeds i c.m. wide, nearly circular, compressed.

A. purpurea, Bolle in Peters' Mossamb. Bot., 1, 6. Unknown to me, but described as "a small tree from Zambesia, with green-grey tomentose, or thickly pubescent
extremities. Leaf-rachis pubescent, with concave sessile glands between the pinned, which are in 8 pairs; leaflets 12 jugate, very shortly petiolulate, oblong, obtuse, thinly pilose, 3 lines long, i lines broad. Spikes equalling the leaves, dense, pilose. Flowers purple. Calyx hairy, with finely pointed teeth. Petals free nearly to the base. Legume not seen. I do not know this plant, nor have I identified it among Dr. Kirk's collections. Dr. Bolle puts it in Mr. Bentham's section
A. rostrata. (New species.)3 Vern. names-3, Aapjesdoorn; 4, Mkaia. Usually a much-branched shrub 2-4 metres high ; occasionally a tree of considerable size.
Two hooked thorns 5-o10 m.m. long, apparently stipular, tend upward; i larger thorn up to 1'5 c.m. long, somewhat hooked, tends downward below the bud. This is consequently one of the worst Acacias for detaining passengers, as upward and downward thorns both catch. Leaves 7-1o c.m. long; the rachis pubescent, with 2 or more glands toward the base; pinned about 7 pairs; leaflets about 14 pairs, 4-7 m.m. long, I'5 m.m. wide. Inflorescence spicate. Spike 5 c.m. long. Pod 7-1o c.m. long, 2-2'5 c.m. wide, the middle part oblong, tapering to the narrow base, and also tapering to the 1-2 c.m. beak, flat, with thin reticulated valves and 1-5 seeds. Frequent in the thorn-veld of Lourenzo Marques and Maputa, usually in moist depressions; when large used along with other kinds known as Mkaia and
not distinguishable in its timber from them Sim 6263.

A. Catechu, Willd. Vern. names-io, Moroga and Nematonga. A large or medium-sized tree, having short, stout, recurved thorns usually present in pairs. Leaves
12-18 c.m. long, the rachis somewhat pubescent, with a sessile gland near the base and several between the pinned; pinnme many; leaflets many, smaller than those of A. caffra. Inflorescence spicate; spikes axillary, 5-10 c.m. long, petals much longer than the calyx. Pod flat, linear, about 6-seeded, o10 c.m. long, 2 c.m. wide.
Zambesia, scarce. Mr. Burtt-Davy, speaking of this species in the Transvaal says :-" Our largest species of Acacia, forming a handsome and striking tree on the river banks of the eastern middle veld, between 2000 and 2500 ft. alt. .... called 'White Thorn . . tall trees with trunks up to i and 2 ft. diam."
A. caffra, Willd., var. rupestris. (New variety.), Vern. names-4, 13, Tole; 15, Mutholwane. Small tree with leaf 15 c.m. long; about 14 pairs of pinna ; about 30
pairs of leaflets to each ; rachis with gland near base and between one or more of the upper pairs. Stem somewhat angular, with recurved prickles 3-7 m.m. long, scattered on its surface. Inflorescence spicate. Spike 7-o10 c.m. long, seldom panicled. Pod 10-12 c.m. long, 1"5 c.m. wide, pointed, tapering to both ends, flat.
The whole tree pubescent. Probably corresponds with A. eriadenia, Benth., but is not specifically distinct from A. caffra. The type of A. caffra was not noticed in the Province ; it is a larger tree, usually near water, less pubescent and more panicled. The present form is frequent on and below the Lebombos, in Maputa and
Marracuene, less common nearer Lourenzo Marques, and not seen in other districts. It occurs in the Transvaal, Natal and Cape Colony. Sim. 6235.

A. Burkei, Benth. Unknown to me ; described by Harvey, as:-" Young twigs and petioles patently hispid; prickles in pairs just below the nodes, recurved; petiole
unarmed or armed, and with a petiolar gland below the pairs; pinna 3-6 jugate; leaflets 5-8 jugate, obliquely oblong or obovate, obtuse or mucronulate, the younger villous at the margin; spikes tufted, loose, peduncled, rather longer than the leaf. Legume? Bark dark ashey-brown, rugged. Leaflets drying pale,
4 lines long, Ij-2 lines wide, the uppermost largest and obovate. Spikes 2-3 inches long." 2
Mr. Burtt-Davy, who calls this Aapjies-doorn cites, along with Transvaal localities, "Manganja hills, Zambesia, fine tree, 30-40 feet high; wood not hard, but tenaceous, used by natives for hoe handles, &c., AMe/ller 9 in Herb Kew."
A. delagoensis, Harms. Concerning this species I know nothing beyond Mr. Burtt-Davy's record, 3 viz. :-" Umbolosi, Schlechter, 11,718, in Herb Lurich. Probably
extends into the low veld of the Transvaal, apparently near to A. Burkei."
A. lasiopetala, Oliv. Unknown to me, described by Prof. Oliver as:-" Extremities uniformly softly hoary-tomentose. Stipular spines, straight or subrecurved,
pubescent nearly to the apex. Young leaves, especially on the rachis, silky tomentose; pinna in 14-22 pairs; leaflets 20-30 pairs, probably often more numerous, not wholly developed in our specimens; gland sessile near the base of the rachis. Peduncles in pairs or solitary from the lower axils, pubescent, 1-2 inches long.
Bracts obsolete. Flowers capitate. Calyx pilose pubescent, lobes ovate obtuse. Petals externally silky, cohering ( or 2 their length, about half as long again as the calyx. Ovary subsessile, glabrous, subtruncate above, with an obliquely inserted filiform style. Fruit unknown. Foot of Impemba Peak, Shire River, Dr.
Kirk." 4 Mr. Burtt-Davy, who has compared Transvaal specimens with those from the Zambesi (Buchanan's), says :-" In foliage and pubescence it is much like A. Rehmanniana, Schinz, but the legumes are large and woody, in shape a little approaching those of A. hebeclada, but longer, glabrous and shining. The bark is
quite different from that of A. Rehmanniana, being pale yellow, soft and papery, at length flaking off."
A. pennata, Willd. Vern. name-4, Inekwa. Scandent by nature, erect when support is absent. Prickles scattered round the stem and between the nodes, often
numerous, not stipular, recurved, i c.m. long. Leaf 12-18 c.m. long the rachis often bearing prickles on its lower surface, and a gland on its upper; pinna 10-15 pairs, or not regularly opposite, leaflets 15-30 pairs, 7 m.m. long, 2 m.m. wide. Inflorescence capitate in axillary and terminal panicles. Axillary abortive branches set with numerous small recurved prickles, and with tendril nature assist the scandent habit, but where there is no support the plant assumes erect habit 4-10 feet high, much branched, and with the inflorescence in lax terminal panicles, with numerous capitate heads and eventually 30 or more pods in a panicle. Pod 10o-15 c.m. long, 2-2"5 c.m. wide, thinly coriaceous, flat, many-seeded. Seeds oblong, 7 m.m. long, dark brown. A bad forest weed. Umbalusi; Lourenzo Marques, &c.

A. retinens. (New species.)' Vern. names-4, Insibebe or behe; 15, Mshakwe. A shrub 2-3 metres high, or occasionally a small tree, gregarious to the exclusion of
other kinds. Stipular spines 5-10 m.m. long, strong, sharply hooked, often altered by insect parasites into hard swollen spines 3-4 c.m. long, I c.m. diameter with the points sharp and hooked. Leaves 2-5-4 c.m. long, with 5-7 pairs of pinna, each with 12-14 leaflets which are 2 m.m. long, linear, pubescent and ciliate. All young parts densely pubescent, including spines, twigs and pods; with age these become nearly glabrous. Inflorescence nearly capitate on 2-3 c.m. peduncles bracted below the middle. Pod 2'5-4 c.m. long, i c.m. wide, straight, flat, dehiscent, with about 4 compressed brown seeds with a cordate spot bordered white on each. Umbelusi and Lebombo (extra-tropical). A most adherent Wacht-em-bitje" said by Mr. Stem to be highly valuable for the rough cordage from the bark, which is too dear for commerce but for durability is not excelled. The curious gall-spines are constantly present and are a curious development; galls of the
same nature also occur occasionally on A. horrida, and more regularly on the exotic A. cornigera. Sim. 6391.
A. arabica, Willd. Vern. names-4,Tchanga or Chenga; 6, Shangaira and Chicai; 15, Isitwete; io, Mungu-m-chen and E. gamo-sena. In this Province a flat-topped tree
3-6 metres high with a rugged black stem, and usually well supplied with straight white stipular spines 5 m.m. to 7 c.m. long, the larger spines up to 7 m.m. diameter at base. I.eaves 7-10 c.m. long; pinnme 6-8 pairs; rachis pubescent; leaflets 10-12 pairs, 6 m.m. long, 2 m.m. wide, linear-oblong. Peduncles clustered, axillary, 3-7
c.m. long, bracted rather below the middle, with capitate or sub-spicate inflorescence and often a few flowers at the bracts; occasionally spicate and capitate inflorescences occur on the same branch. Pod 15 c.m. long, i c.m. wide, stipitate, straight, moniliform, glabrous or pubescent. The type of this species belongs to North Africa; the South African form is var. Kraussiana characterised by long spines and deeply crenate but scarcely moniliform, tomentose pods. Seldom gregarious, but more generally distributed throughout the Province, as also throughout tropical and sub-tropical Africa than any other species. Abundant in Maputa and Natal; seldom of timber size, but it makes first-rate fuel. "On the Upper Nile this species attains a large size, the trunk measuring 8 or io feet in girth. The wood is used in boat-building, and the astringent pods are largely used in tanning." From some of the forms of this tree the gum arabic of commerce is obtained.
The pod is known as, io, Messieo or Issaeii or Ensio.

tree usually spreading more than its height. Pinna 2-4 pairs, leaflets 8-12 pairs, linear-oblong. Inflorescence capitate; peduncles many together in axillary clusters, or by the absence of leaves forming terminal panicles, bracteate below the middle; flowers bright yellow, sweet scented. Pods 5-12 c.m. long, 6-12 m.m. wide, straight, falcate, or more or less twisted, thinly coriaceous, glabrous, dehiscent, acute, many-seeded, compressed, not or hardly constricted between the seeds. Spines in pairs, stipular, straight, acute, from 1-12 c.m. long, white. This is the most common species in Cape Colony, Natal, and Transvaal, but is less common in this
Province, and in the low tropical districts absent. For illustration and uses see "Forest Flora of Cape Colony," p. 2 I 1, Plate LXI.
Var. t-ansvaalensis, Davy, differs in being pubescent on its younger parts.
A. seyal, Delile. A small tree 3-5 metres high, usually growing in straggling fashion in dense impenetrable masses, and occupying more or less wet ground. Spines 2-5
c.m. long, slender, white; leaves 5 c.m. long; pinnM 3-4 ; leaflets 8-20, 5-7 m.m. long, 2 m.m. wide or less; peduncles axillary, several from an axil, 2-5 c.m. long;
flowers capitate; pods 8-12 c.m. long, 6 m.m. wide, much constricted between the seeds; valves thinly coriaceous. Too near A. horrida, from which the more constricted pods form the best distinction, and still with a considerable indescribable difference which any native can recognise. Frequent in Maputa and

A. natalitia, E. Mey. Concerning this species which Mr. Burtt-Davy collected on the Komati River, he says:-" Nearly related to A. horrida, but apparently a valid
species, distinguished by the much narrower leaflets and characteristically pale bark, as compared with the dark-brown, almost black, bark of A. horrida."
A. hirtella, E. Mey. Vern. names-4, Mungu-manzi; io, Egamosena. A very robust tree, densely pubescent on the younger parts, with heavy dark-green foliage.

and 6-9 seeds, which hang out after the pod opens. Pod tapering to the base, roundly pointed at the apex. This tree agrees with Harvey's description ("Flora Capensis," II., 281), but A. hirtella of my "Forests and Forest Flora of Cape Colony" is different, and is probably a still unnamed species, which was not seen in Portuguese territory. The present species is abundant in Lourenzo Marques, Maputa and Marraquene, and it also occurs throughout the districts (tropical and extra-tropical) explored by me, often as a fringe just above the mangroves on saline mud flats. Along with other thorny species it shares the name Mungu-m-chen
(i.e., prickly-thorn).

A. Xanthophloea, Benth. Vern. names-r, Fever-tree; 4, Kamba, Camba, Shi-kamba, and Mhlafunga. Lofty tree, up to 30 metres high, with stem to I metre
diameter; growth mostly on top, and on a few scattered branches. Stipular spines usually present, in pairs, 1-4 c.m. long, slender, straight, acute, white. Bark of the stem glaucous green, smooth. Leaves 5-15 c.m. long, 4 c.m. wide or less, 2-pinnate; rachis variable from terete to sulcate, and usually with one oblong gland near the base; pinne 4-7 pairs, leaflets 0o-i5 pairs, 6 m.m. long; the leaves and young growth at first scaly-pubescent, but soon almost glabrous. Inflorescence capitate, heads globose; peduncles 3 c.m. long, 3-bracted near the middle ; many from I axil, the peduncles and small leaves produced on abortive axillary branchlets. Specimens frequently occur where (by fungoid fasciation ?) the inflorescence becomes abnormal, produced into a scattered raceme 5-7 c.m. long, or paniculate through the production of secondary racemes from the axils of the bracts. Pods numerous from i flower, not seen at maturity. Several writers have commented on this tree not bearing fruit. I think it probably ripens rapidly and falls without being woody, as I saw no trace of old fruit, though flowers and young fruits were abundant. A stately tree with a ghastly hue on the stem, growing usually on flat clay soils, hence often co-present with malarial fever, and known as fever tree. The timber seems sound when cut, but soon cracks badly and decays, and is useless for most technical purposes, and subject to insect-boring almost as soon as cut. Frequent at Umnibelusi, Matolla, &c., and seen at Chai-chai, Manjikesi (scarce and only near the panis), Mutambe, Inhambane (extra-tropical), Quelimane and Nhamacurra, but not in large quantity altogether. Occurs also in the Transvaal low veld, Rhodesia, and further north, and in Northern Nigeria.
"The bark of the main trunk and branches exfoliates leaving a layer of new bark of yellow colour and powdery surface, as though covered with a lichenoid
growth Said to produce gum, but this is not a noticeable feature.

Several other species of Acacia are on record, unknown to me and concerning which my information is insufficient. Among these are :A. Petersiana, Bolle in Peters' Mossamb. Bot. I. 4, concerning which Prof. Oliver, in Flora of Tropical Africa," states that so far as he can judge it "must be very
near A. spirocarpa. The fruit however is unknown. The leaves are described as hairy, not exceeding one inch in length, with 1o pairs of pinne, leaflets very small, linear, in 6-20 pairs. The involucel is inserted in the lower part of the peduncle." But Burtt-Davy (Kew Bulletin No. 4, 1908, p. 16o) doubts if A. spirocarpa, Hochst, occurs so far south as the Transvaal, and refers his Transvaal specimens to A. spirocarpoides, Eng1., of which I have no description. A. spirocarpa is
characterised by exceedingly twisted pubescent pods and capitate inflorescence.

Central flowers sometimes different, with short staminal sheath. Legume dry, dehiscent or indehiscent, several-seeded. Leaves bi-pinnate. Trees
or shrubs with or without spinous branches.
A. Forbesii, Benth. A spreading tree, 3-7 metres high, much branched, bushy or flat. Twigs rigid; stipules 6 m.m. long, lanceolate; inflorescence axillary on the
young shoots. Leaves 5-7 c.m. long and wide; pinnte 2-4 pairs, leaflets 7-12 pairs, at first obliquely oblong, 7 x 2 m.m., afterwards linear through revolute margins; the main vein parallel to and near the upper margin. Rachis with a gland below the lower pair and between the upper pair of pinned; rachis, veins and margins of Burtt-Davy in Kew Bulletin No. 4, 1908.

An important timber tree for wagon-wood wherever obtainable, as it is in Cape Colony, Natal, and West Tropical Africa, while Sir J. Kirk found it in Mozambique district at the foot of Mount Tschiradzura, 3000 feet, and near Munguzi. This tree is easily recognised, and I did not see it in the Province, but think it probably extends along the western border. For uses and
illustration see "Forest Flora of Cape Colony," 215, Plate LXIII.

"Drupe sub-globose or plum-like, with
a thick bony 2 or i-celled putamen; pulp strawberry-like in flavour." Found in Zambesia by Sir J. Kirk. Other species occur northward and westward.
A large Family with considerable range of characters and as it is represented in the ligneous flora here by only r aberrant species the characters of that will suffice.
128. BREXIA, madagascariensis. Bot. Reg. t. 730. A very variable glabrous shrub, 3-5 metres high, growing among mangroves on tidal mud from Delagoa Bay northward.

Petals 4, unequal, plaited, rising from the mouth of the calyx, the limb wider than deep and narrowed suddenly into a narrow claw; stamens 8, 4 rising from below the petals and 4 alternate with them, all outside the disc, incurved when young, finally much exserted. Pistil slender, pointed; ovary i-celled with 2 ovules; the tube breaking off above the ovary at an early stage. Fruit unknown.
Sent from Mozambique together with Weihea (?) sub-peltata, evidently mismated, as "Mocurusse;" presumably this was scandent on or growing intermixed with the Weihea, which, as shown by the attached timber specimens, owned the native name. No further information is to hand as to its habit or habitat. Sim 6393.

North of Quelimane it was not noticed, except in one place between Mucuba and Nhamacurra, but there it was abundant for half-a-mile, and no other tree mixed
with it except a small Protea.
"This species may be readily distinguished from all other African Combreta by its glandular style. The wood is described as being exactly like that of lignum-vitae. The native name for it in the Mozambique country is A1ozamnbiti." I

Sent from Mozambique in connection with an application by the Railway Department as to its suitability for sleepers; also collected by me in dense pure thickets in kloofs on the Lebombo Mountains (extra-tropical) where its timber is well known, but not seen elsewhere. In the absence of flowers and fruit the genus of this tree cannot be definitely decided, but the stipules afford a strong key to the Family. No trace of flowers or fruit was found in the Lebombos, where however I was informed separately by all my informants, English, Dutch, Kafir and Swazi, and unknown to one another, that bees nesting in this tree made poisonous honey.

contact with the timber or by the source of supply no one knew, but it is the only tree, so far as I know, which has such a reputation. I saw no outwardly damaged
tree, though I saw all ages, fine, clean, straight stems in every case; but I was informed that the very large trees are usually hollow. Sim 6387.
136. CASSIPOUREA. Glabrous trees with opposite or verticillate entire leathery leaves, caducous intrapetiolar stipules, axillary inflorescence, superior 3-4 celled ovary with
filiform style and 2 pendulous ovules in each cell. Calyx campanulate, shortly 5-7 lobed; petals 5-7, small, fimbriate at the apex, and inserted on a crenulate disc at the base of the calyx-tube ; stamens 10-14, with filiform filaments, united below. Ovary 2-celled, cells 2-ovuled. Fruit ovoid, ultimately dehiscent; cells iseeded ; seeds arillate; albumen fleshy. A small genus into which Dactylopetalum might be merged.
C. verticillata, N. E. Brown. A small evergreen tree, with ternate and opposite (or sometimes 4-nate) oblong coriaceous entire or almost entire leaves, io c.m. long, 4-5
c.m. wide, axillary flowers, many crowded together, and dehiscent fruits I c.m. long, resembling those of Gymnosporia, and with similar yellow arillate seeds, rather
conspicuous on the tree for a time. Present but not common through Maputa, Marracuene, Gaza and M'Chopes. For illustration see Natal Plants," Plate 276.
Trees or shrubs with simple, entire, leathery exstipulate leaves, often with pellucid dots ; paniculate or axillary inflorescence, hermaphrodite flowers ; inferior ovary sepals and petals 4-5 ; stamens numerous, free ; ovary 2-3 celled ; ovules few or many in each cell, from or near the base, style simple, filiform ; fruit a berry or a dry dehiscent capsule. Seeds few, exalbuminous. A large Family, well known by such representatives as the Australian Eucalypts (Gum-trees), the Guava, Rose-apple, Jambolan, Brazilian Cherry, Cloves, Allspice, Myrtles, Australian Myrtles, Pomegranates and Bottle-brushes. I am not aware that the Clove (Caryophyllus) comes within the limits of the Province, though it occurs on the coast and islands further north.
137. EUGENIA. Calyx-tube short, flat, and disc-like or cup-shaped, limb 4-5 parted; petals 4-5, inserted with the numerous stamens on the edge of the calyx-tube. Ovary
inferior, 2-celled. Fruit a fleshy berry, crowned by the calyx-lobes, usually i-seeded. Seed, round, hard, stone-like. Trees or shrubs with pellucid dotted, simple,
entire, glabrous, shining, opposite leaves, and terminal paniculate or axillary inflorescence. Principally a Central and South American genus.
E. cordata, Laws. Ve-n. names-i, Water-tree; 2, Water-boom; 4, 15, Much6, Muhlu, or Munchlo; 13, Umswi and Umdoni; i5, Mkose. A medium sized, roundtopped, glaucous tree, with opposite, nearly sessile, widely eliptical, bluntly pointed and somewhat cordate, entire, glabrous, coriaceous, sub-glaucous leaves 5-10o c.m.
long, 2-5 c.m. wide, and paler on the under than the upper surface. Panicle terminal, cymose, many-flowered, with angular glabrous branches, trichotomously forked, all forks and flowers subtended by linear deciduous bracts, or the lower by leaves. Calyx-tube cup-shaped, with blunt shallow lobes. Petals united into a calyptra and breaking off at the base. Stamens numerous, at first inflexed, afterwards spreading, the numerous anthers forming the showy white part of the flower.
Pistil cylindrical, as long as the stamens. Berry 12 m.m. long, oblong, acidulous, more or less edible, usually i-seeded. All the younger wood quadrangular. Stem up to 6o c.m. diameter; usually grows near water; seldom found in dense forest, but often where grass fires clear off all other kinds. Frequent in the extra-tropical parts of the Province, almost the only tree in the M'Chopes pans, and present also though less frequent in the tropical districts. Abundant in Cape Colony and Natal, and in writing of "Plant association at the Victoria Falls," Miss Gibbs arranges the local flora there in 3 groups, the first of which is the open veld, and concerning the others she says:-" The second region seems to be limited to the immediate banks of the Zambesi River and islands above the Victoria Falls in which the dominant plant is Euigenia guineensis. The third would include the bog edge of Livingstone Island and that of the opposite Rain Forest, with the famous Rain Forest proper, and Knife Edge, where Eugenia cordata predominates."' To make its timber durable, water-seasoning is necessary. For illustration see
"Forest Flora of Cape Colony," p. 226, Plate LXXI. fig. 3.
E. guineensis (=Syzygium guineense, Guill & Perr, Fl. Seneg. 1. 315, t. 72). Vern. names-6, Kurre or Mkurre; io, Muti kurru or Mokosa; ii, Morimonico. A
large glabrous glaucous tree, 10-i5 metres high and up to i metre diameter. Leaves ovate-acuminate, petiolate, not cordate, usually tapering to the petiole.
Panicle 15-25 c m. across, many-flowered, terminal. More common than E. cordata in the tropical districts and often found inside the forest near streams; in the
extra-tropical districts it is present but less common. The general habit is similar to E. cordata, but the leaf-form is different. = E. owariensis, P. Beauv.

Leaf like that of the Loquat, 15-30 c.m. long, 5-10 c.m. wide, widely-lanceolate-oblong, tapering below, bluntly pointed, and bluntly toothed on the margin. Raceme 50-75 c.m. long, many-flowered; flowers in opposite pairs; calyx-tube ovoid, limb 4-lobed; petals 4 ; stamens many, connate at the base, forming a ring, and with white spreading filaments 4 c.m. long; ovary 2-4 celled; fruits produced several on i raceme, shortly peduncled, 4-5 c.m. long, 2'5-3 c.m. diameter, bluntly 4-sided, ovate, and crowned by the persistent 4 sepals and 5 c.m. pistil. Seed solitary, but pendulous from a strap-shaped placenta rising from the base and bearing several other abortive ovules. Frequent in swampy localities and along fresh or nearly fresh rivers throughout the Province. The bark is used for cordage. Timber white, soft,
light, seldom used.

Trees, shrubs or herbs; calyx-lobes valvate, with or without intermediate teeth. Petals often corrugated in bud; stamens definite or indefinite; ovary free or partly adherent to the calyx-tube, several or many-celled; cells usually with many ovules. A heterogenous group, including only one tree in the Province, so far as I know.
139. SONNERATIA. A departure from the type of the Family in having indefinite stamens and the ovary partly adherent to the calyx-tube. Only one African species
as under :-S. acida, Linn. Vern. names-o, Mucatanga, Mevate. A shapely glabrous evergreen tree or bush, inhabiting tidal mud, frequent from Beira northward, and having
opposite, decussate branches swollen at the nodes; opposite oval leaves 7-o0 c.m. long, 5 c.m. wide, tapering somewhat to the base, and firmly coriaceous; and large terminal flowers, solitary or 3 together, at first shortly bracted. Calyx leathery, 6-7 fid, lobes 3-4 c.m. long, I c.m. wide ; petals absent in the flowers examined, probably caducous, described as "strap-shaped, ( length of the lobes of the calyx." Stamens numerous, inflexed in bud; ovary adherent to the calyx-tube at its base only, flattened, many-celled; ovules numerous in each cell. Style slender, 4 c.m. long, usually bent, and with a flat rayed stigma. Fruit 5 c.m. diameter, 3-4 c.m.
deep, woody, set in but free from the persistent calyx and tipped by the persistent style. Fruit bursting irregularly from the base, leaving the central axis attached
to the calyx. Seeds 6-7 in each cell, radiating from the centre of the fruit. Cotyledons oily."

The timber is however always soft and useless. All the varieties mentioned occur in the
Province as also in Cape Colony and Natal, and the species occurs also in the Upper Nile and Abyssinia.
Floral characters almost as in Umbellifere, but flowers constantly regular, petals valvate in aestivation, fruit more or less fleshy, and the stipulate leaves digitately 5-7-9 foliate, while the inflorescence is often not umbellate.

Quinine, Coffee and Ipecacuan are among the products of the Family and such garden plants as Gardenia, Ixora, Bouvardia, Rondeletia, Manettia, Burchellia, Pavetta, Webera, &c., belong to it. It is not much noted for timbers, and the local representatives with the exception of Adina and Gardenia are mostly shrubs rather than trees ; as they hardly deserve mention here from their forestal importance they are only mentioned with synoptical descriptions.
144. ADINA. Flowers arranged in pedunculate axillary compact or confluent globular heads, each head on a common bracteolate receptacle. Fruit a 2-celled capsule,
bursting apart either from below or above, the central placenta remaining in position supporting the remains of the flower; seeds many, small, winged at both ends.

Stamens 5, inside the corolla-tube. Style twice as long as the corolla, with a club-shaped stigma. First-rate wagon-wood for spokes, beams, &c. ; stem sometimes 3 metres diameter in Swaziland and Eastern Transvaal, in creeks and gullies on white granite. Frequent in Magenja da Costa and Nhamacurra (Tropical); seen also Umbelusi and in the Lebombo kloofs near Estatuene, Maputa Div. (Extratropical). Occurs also in Nile-land. Mr. Burtt Davy writes (Kew Bulletin No. 4, 1908) :-" The Transvaal material at Kew so named is now referred to A. Galpini,
Oliv.," of which I have no further information.

Occurs in Maputa on the Lebombo kloofs and in M'Chopes (extratropical), as also in Magenja da Costa near Macubella, and in Nhamacurra (tropical).
G. Thunbergia, Linn. Vern. names--i, Wild Katjepiering ; 3, 14, Buffelsbal ; 4, Chiselala and Imbalangwe; 10, Nepaia and i-tirigo; 13, Umkangaza; 15, Vala
sanguin (Kaffraria) and Um-valasangwaan (Natal). A small much-branched tree 3-5 metres high, with smooth white unarmed stem up to 30 c.m. diameter, and rigid opposite or ternate branches and branchlets, or sometimes prostrate or mostly subterranean. Leaves very variable, lanceolate on seedlings for the first few years, afterwards ovate, obovate, or widely elliptical, tapering to the base, rounded or acute, entire or with one or more irregular lobes or teeth, glabrous, veined, and bearded in the axils of the veins. Leaves opposite or 3 together, shortly-petioled. Flowers terminal, solitary, strongly scented, usually 8-merous, large, white and attractive. Calyx green, foliaceous, 4-5 c.m. long, cleft on i side, and with 5-10io shortly-stalked, unequal, leaf-like lobes. Corolla salvershaped, 8-lobed, the tube 8-1o c.m. long, r c.m. diameter, the limb 7-10 c.m. across, pure white and regular. Stamens about 8, exserted, twisted; stigma exserted, 2-lobed. Fruit woody, very hard, oval or oblong, 5-10 c.m. long, 5 c.m. diameter, many-seeded, crowned by the large calyx-scar and with about 5 (or sometimes up to io) imperfect dissepiments. The fruits remain on the trees for several years, increasing in size, and finally are either smooth or rugose, but usually white. An exceedingly variable species, possibly including several species, though I have not noticed what I should consider specific differences either in Cape Colony, Natal, or this Province, in all of which it is widely distributed, but nowhere plentiful. In the Journal of the Linn. Soc., Botany, Vol. XXXVIII., No. 268, Feb. 1909, I)r. Otto Stapf and Mr. J. Hutchinson give a monograph of the forms included in the group which has hitherto passed as this i species; they make it into 15 species and say finality has not yet been reached. About half of these species are recorded from this Province, but the monograph arrived too late to allow me to use it on the fresh plants, consequently no attempt is made to divide this species here. The forms mentioned as

belonging to this Province are G. subacaulis, S. & H. ; G. Jovis-tonantis, Hiern; G. Thunbergia, Linn. (with limited characters); G. Saundersie, N. E. Brown, in Kew Bull. 1906, p. o104 ; G. asperula, S. & H. ; G. cornuta, Hehnlms. in Hook. Icon. P1. t. 2809; G. spathulifolia, S. & H. For illustration see "Forest Flora of

They are mostly erect or straggling shrubs 1-3 metres high, known as Wild Coffee and closely resemble Coffee in habit; there are many species of no technical value, and these are therefore not described separately here. In the Flora of Tropical Africa" 2 1 species are described ; in Flora Capensis" other 4, and there are others besides. In "Forest Flora of Cape Colony illustrations are given on Plate LXXXV. of Diplospora africana, Sim (fig. 3); Kraussia lanceolata, Sond. (fig. i), and Tricalysia capensis
(fig. 4). Native names included in this group are:-4, Nakaranga or Nukajanga; 6, Rutatsakanye; io, Ugatadwe and Manyeba-gorewa; 15, Patankos.

For illustration see "Forest Flora of Cape Colony," Plate LXXXV. fig. 2. Frequent in the southern portion of the Province, as also in Natal and Cape Colony. What was taken for the same species was also seen in Magenja da Costa, but as it was without flower or fruit it may have belonged to one of the other species, which are all unknown
to me and of which the descriptions are extracted from the "Flora Capensis."

Several other small shrubby Cape species occur along the Lebombo Range, and in the north two small species are described, viz. :-P. macrosepala, Hiern, with oval glabrous leaves, and P. gracilis, Klotzsch, with elliptical more or less pubescent leaves.
A curious shrub 2-7 metres high, with thick rigid branches, long croton-like lanceolate leaves 10-40 c.m. long, 2-3 c.m. wide, terminal paniculate inflorescence, and round fruits 6 m.m. diameter, occurs in the Lebombo range in Maputa and Marracuene, and also in the more inland portions of Magenja da Costa and
Nhamacurra, and appears to belong to Pavetta, but my material is insufficient for determination. It is known locally as (15) Hlangushan.
16i. COFFEA. Shrubs or small trees with opposite leaves and branches, intrapetiolar stipules, axillary or terminal solitary or clustered white fragrant hermaphrodite flowers,
and oblong i-2 seeded berries. Calyx-tube short, toothed, not accrescent; corolla salver-shaped, 5-7 merous, lobes twisted in aestivation; stamens 5-7, partly or wholly exserted.

C. stenophylla, G. Don. Veirn. name-i, Inhambane Coffee. A glabrous shrub 2-5 metres high, with opposite leaves and branchlets. Leaves lanceolate, elliptic, or
obovate, bluntly pointed or varying to candate-acuminate, sub-coriaceous, 5-io c.m. long, 1-3 c.m. wide. Flowers axillary, 1-3 together, shortly pedunculate; corollatube 6 m.m. long, lobes 6-8, oblong; the flower 2-2'5 c.m. across; anthers exserted. Berry oblong, i5 c.m. long, black. Frequent in moist parts of the forest from M'Chopes northward, often cultivated, cultivation being started either by moving young plants from the forest, or by burning down the forest when the Coffee is the first tree to start again. C. stenophylla has been regarded as a West African species; the East African plant differs slightly in having more distinctly lanceolate leaves, hut I think is not specifically distinct. Inhambane Coffee is not however entirely the product of this bush, as other exotic species are cultivated for their seeds, and the distinctive flavour of Inhambane Coffee is probably due as much to treatment as to species. Though less subject to coffee disease than the exotic kinds, the local species is not proof against it, and with the forests full of nearly related Rubiaceous trees all more or less subject to that or closely related fungoid diseases, coffee culture can hardly be regarded as a promising branch of agriculture unless future developments show some easy and cheap method of keeping the
pest in hand.
Other species said to be indigenous in the north are:-C. Zanguebarie, Lour., having oval or obovate thin leaves, axillary flowers, and the berries longitudinally nerved; and C. racemosa, Lour., having ovate-lanceolate leaves and sub-terminal erect racemes. The cultivated coffee is mostly C. arabica, Sim, having
oval or elliptical leaves and axillary clusters of flowers.
162. TRIAINOLEPIS. Shrubs with pubescent or glabrescent opposite leaves, small tricuspidate stipules, and hermaphrodite small, 5-7 merous flowers having 5-7 celled
ovary and solitary erect ovules; the flowers arranged in terminal corymbose cymes.

A small tree in the forests of Magenja da Costa, known as io, ikalago, of which I have not seen the flowers, appears to belong to Rubiaceie and to be not previously included herein, but my material is insufficient for full determination. It has opposite obovate-acuminate leaves 7-12 c.m. long, 3 c.m. wide, firmly pubescent above and on the veins below ; young wood pubescent ; stipules acuminate from a wide base; panicle o10 c.m. wide and long ; fruit globose 5-6 mm.
diameter, having a large areole with 5 short teeth on its margin ; fruit 2-celled with i peltate flat seed in each cell, each seed having several (4-6) large and beautifully fringed peltate scales upon its surface. These scales are oblong 2-3 m.m. long, and unlike anything of the kind I have seen elsewhere. Sim 6oi and 6053.
For Lepipogon obovatum, G. Bertol, an Inhambane shrub unknown to me, see Flora of Tropical Africa," III. 247.
Flowers in several-flowered or usually many-flowered heads, on a common receptacle, and surrounded by a common involucre; which heads are popularly regarded as separate flowers. Flowers 5-merous, regular or bilabiate, or the inner florets regular and the outer with strap-shaped corolla in the same head. Calyx adherent to the corolla,

and with the limb absent or modified into few or many scales, bristles, hairs or feathered hairs, and known as the tappus when surmounting the fruit. Corolla either all tubular, all bilabiate, all strap-shaped, or the inner tubular and the outer strap-shaped in the same head, in the latter case the larger strap-shaped and often coloured outer florets making the resemblance of the head to a flower with these as petals the greater. Stamens 5, filaments distinct, anthers cohering round the style. Stigma bifid. Ovary inferior, i-celled, with i erect ovule, forming an indehisccnt i-seeded fruit, often crowned by a sessile or stalked pappus. Seed exalbuminous. Leaves usually alternate, exstipulate. Flowers perfect, monecious or dicecious ; perfect, female and neuter florets being often in i head.
The largest Family for the whole world and for most localities, usually represented by herbaceous weeds; in this Province only a very few attain shrub or tree size. Bitterness is the most common principle in the Family; a few, as the lettuce and the chicory, are edible under. certain conditions, and many are used in medicine. Garden flowers are numerous, including the I)aisy, Marguerite, Dahlia, Marigold, Cineraria, Senecio, Pyrethrum, Sunflower, Aster, Chrysanthemum and Helichrysum.
163. VERNONIA. Herbs, shrubs or small trees, with alternate leaves, cymose-panicled inflorescence, and usually many-flowered capitula of white, pinkish or purplish,
tubular, hermaphrodite flowers. Style branches slender. Pappus composed of numerous setae. Very diverse in habit and appearance.
V. senegalensis, Less. V7e-n. na ies-4, Pahla-pofu, Pahla-kapfa, Insumbalume, Shirangela-nguba; so, Mesagulo; 15, Nyatsele. A tomentose much-branched shrub
2-6 metres high, occasionally up to 30 c.m. diameter of stem. Leaves obovate-elliptical, tapering to both ends, sinuate or lobed, o10-15 c.m. long, 5-8 c.m. wide,
ultimately glabrescent. Panicle terminal, often 30 c.m. or more across ; heads r'5-2 c.m. diameter, involucral bracts blunt, corolla white or tinged with purple; pappus grey or rusty brown. Frequent throughout the Province; or it may be that several species of Vernonia having the same general appearance are taken
collectively under the common names given above.

Corolla gamopetalous, 5-lobed, each segment bearing a sessile stamnen on its face. Ovules about 4, bedded in a globose central placenta.
Fruit i c.m. diameter, globose, glabrous, i-seeded, the seed hard and horny. For illustration see "Forest Flora of Cape Colony," Plate XCIII.
Concerning the Abyssinian M. simensis, Hochst, Baker remarks, "differs from M. melanophleos mainly by its longer pedicels and more numerous flowers in a cluster," while his descriptions of M. querimbensis, Klotzsch, and M. melanophleos only indicate the sexual differences of the latter already referred to.

8o Forest Flora of Portuguese East Africa.
M. Henriquesiana. Vern. names-5, Menjela; 6, Banjela and Rungulo. A large or very large tree, sometimes 20 metres high, i metre stem diameter, with spreading
branches and abundant heavy foliage. Leaves crowded upward, variable in form from widely lanceolate, elliptical or obovate to nearly round, usually bluntly pointed, tapering to the 2-3 c.m. petiole, 5-7 veined on each side, glabrous and green. Flowers axillary, several together, the peduncles 2 c.m. long and like the brown calyx shortly pubescent. Floral parts 6-merous (seen in bud only); fruit oblong, 2 c.m. long, edible. Young growth set with scattered loose white hairs. A noble tree, with a thick rough bark containing a large quantity of Caoutchouc. Dr. Feriera on whose farm near Manjacaze, Lower Gaza, a large quantity of it grows, has had this latex expressed and sent to Europe, where it was considered suitable for many purposes and valued at 2/6 per lb. As the latex does not flow with sufficient force to allow of its being collected from the surface, expression is the only means of obtaining it, and I doubt whether under present conditions and for the value stated, this can be done with profit. The latex is there as it is in the other species of Mimusops, but till cheaper extraction can be devised or higher value obtained I fear it must remain there. The tree is frequent in Gaza, M'Chopes and Inhambane, and what appearad to be the same species was also seen in
Magenja da Costa.

Plate XCVI.
M. caffra, E. Mey. Vern. names-i, Red Milkwood ; 4, 5, 6, Tole or Chole; 13, Um-Nweba and Um-tunzi. A somewhat hoary or glaucous evergreen tree or shrub
forming a large proportion of the sea-dune vegetation, but also extending inland on sandy soils. On the dunes it grows down to the watermark, fully exposed to sea-winds, and is consequently usually dwarfed in stature and heavily branched from the base where these winds prevail. In shelter it gets up to about io metres and 30-45 c.m. diameter, but even there it is heavily branched and very gnarled and crooked and consequently yields first-rate knees, &c., for boat-building.
Branches, leaves and inflorescence abundantly rusty-pubescent when young, and retaining the pubescence or silkiness, at least on the under surface of the leaves and on the pedicels and calyces. Leaves 3-5 c.m. long, 2-5 c.m. wide, firmly coriaceous, widely obovate, often rounded or emarginate at the apex, tapering to the short petiole, and often with the margin reflexed. Flowers usually in clusters of 2-4 in the axils along the branch; peduncles 2-3 c.m. long. Flowers 8-merous, corolla usually in 2 rows, staminodia ovate, acute, hairy. Ovary 6-8 celled, hairy. Fruit 2 c.m. long, 1-5 c.m. wide, tapering to the point, red, edible by children,
i-seeded, the seed shining brown. Abundant along the coast and through M'Chopes; as also in Cape Colony and Natal.

Leaves obovate or elliptic-obovate, acuminate, rounded at the base, glabrous, shining 10-20 c.m. long, 3-6 c.m. wide, with petioles 1-3 c.m. long. Pedicels 2-5 c.m. long, dense but minutely rusty-pubescent, as also are the scales, calyces and
young fruits. Flowers 8-merous. Petals 24, often fimbriated at the apex; filaments villous; staminodes hairy. Fruit elliptical 3-4 c.m. long, 2-5 c.m. diameter,

Flowers dicecious or rarely hermaphrodite, regular. Calyx gamosepalous, 3-6 lobed, often accrescent in fruit. Corolla gamopetalous, 3-6 lobed, lobes contorted in bud. Stamens almost sessile, usually several times as many as the corolla-lobes, in one or more rows ; in female flowers abortive, few or absent. Anthers introrse, lanceolate. Ovary superior, several-celled, in male flowers rudimentary; ovules pendulous, anatropous, solitary or in pairs, usually twice as many as the styles. Fruit coriaceous or more or less fleshy, sometimes edible; seeds albuminous, horny. Hard-wooded unarmed trees, shrubs or shrublets, with exstipulate, alternate, opposite, sub-opposite or ternate, simple entire leaves, and axillary simple, racemose or paniculate inflorescence, and without milky juice. A tropical and sub-tropical group of little forestal value.
171. ROYENA. Flowers apparently hermaphrodite, often actually unisexual, or one sex weak. Calyx 5-fid or 5-partite, pubescent, sometimes enlarging after flowering.
Corolla with an urceolate tube, and spreading 5-fid limb which is twisted in aestivation.

Fruit globose or ovoid, pointed by the style, coriaceous or fleshy, indehiscent or splitting. An African genus of shrubs or small trees, well represented in South Africa, of which several species extend along the Lebombos and through the M'Chopes, and one, R. pallens, Thun., is frequent in the inland parts of Magenja da Costa and Nhamacurra. None of these are tree or of timber size; several share with Euclea the Vern. name, 4, 15, Magitamus or Ketums, and one species is called, 4, Inthababane. Concerning several Royena-like
trees, see under Diospyros. For illustrations of the species see "Forest Flora of Cape Colony," p. 256, Plates XCVIII., XCIX., and CIII.
I72. EUCLEA. I)icecious. Calyx 4-5 lobed, not accrescent. Corolla bell-shaped, 4-5 fid or lobed, twisted in bud. Male flower with 10-32 stamens inserted on the base of
the corolla-tube, and having a rudimentary ovary; female flower with no stamens, but a 4-celled, 4-ovuled, usually pubescent ovary, and 2-lobed styles. Fruit globose, indehiscent, i-seeded. Evergreen trees or shrubs with alternate, sub-opposite, opposite or ternate, simple exstipulate leaves, and axillary racemes or panicles of small yellowish flowers. An African genus of shrubs or small trees, usually hard-wooded, and with very undecided characters. In Cape Colony there are at least 15 species (see "Forest Flora of Cape Colony," page 26o, Plates CI., CII., CIII., CIV.); several of these extend along the Lebombo range, and also along the sea dunes and through M'Chopes, and several similar if not identical species are present in Magenja da Costa and Nhamacurra. They are of no forestal importance or value; and the Verin. names overlap the species. Among these are, 4, Hlangula and Quetamunzi; io, Mlala or Mulalo; 4, 15, Magitamus or Ketums. Among
species belonging to this Province not included in the "Forest Flora of Cape Colony" are the 2 following, transcribed from the "Flora of Tropical Africa," viz. :" E. divinorum, Hiern, Monogr.

metres high, with very horizontal densely foliaged branches. Twigs numerous, slender, pubescent when young. Leaves alternate, often distichous, oval, inch long, coriaccous, glabrous above, paler below, shortly petioled, and when quite young pubescent on the petiole, midrib and leaf-margins, but soon glabrous Growthbuds enclosed in hard brown ciliate scales. Flowers axillary, solitary or 2-3 together, almost sessile, inconspicuous. Calyx cup-shaped, without lobes, glabrous.
Corolla small, externally hispid, 3-lobed. Staminodia in fertile flower 6-9, separate, glabrous. Ovary glabrous, 3-celled; cells 2-ovuled. Fruit I'5 c.m. long, acornshaped in the green calyx-cup, yellow when ripe, rather succulent though hardly edible. Frequent in the Maputa Lebombos, usually as a shrub ; occurs also in M'Chopes (extra-tropical) and Magenja da Costa (tropical). In Cape Colony and Natal it is confined to the coast-belt, but in this Province it extends at least 50
miles inland. For illustration see Forest Flora of Cape Colony," p. 259, Plate C.
174. DIOSPYROS. Trees or shrubs, with alternate shortly petiolate leaves, and usually small axillary solitary or shortly cymose flowers. Calyx usually campanulate and
4-5 lobed, rarely 3 or 6-lobed, often accrescent in fruit. Corolla tubular or campanulate or rotate, usually 4-5 lobed; lobes usually spreading or recurved. Stamens 6-many, usually about 16 and more or less united by their base in pairs or otherwise, inserted at the base of the corolla or hypogynous, in female flowers absent or usually fewer than in the male and abortive; anthers linear or lanceolate; filaments usually shorter or almost obsolete. Ovary globose, ovoid or conical, 4 or 8celled, glabrous or hairy, in male flowers rudimentary; styles or style branches 2-4, stigmas usually emarginate ; ovules solitary. Fruit globose, oblong or conical, coriaceous or thin skinned, often pulpy inside and edible. Seeds r-8, oblong or hemispherical or globose ; albumen uniform or ruminated." I was singularly unfortunate in regard to this genus, for while it is believed to be fairly well represented in the Province, not one flower was found, and consequently the leaves, if found, must remain among my incognitae. The fruit alone is insufficient for identification, but 2 species collected by me appear from the fruits to be Diospyros,
viz. :
D. sp. (Sim 6251.) Fern. names-4, Toma or Um-toma; 3, Jakals-besje. A large tree, found mostly quite leafless, but with nearly globose, several-seeded, sessile

Leaves in the first stage of development scabrid-pubescent, afterwards pubescent or glabrescent, widely lanceolate, elliptical or obovate, io c.m. long, 1-3 c.m. wide. Soft white sapwood; timber said to
make good felloes. May be D. mespiliformis, but I think not. Umbelusi and toward the Lebombos (extra-lropical).

accrescent, spreading, with 5 cordate or reniform puberulous segments and a disc i c.m. across. Seldom of timber size.
The following specific descriptions are mostly condensed from the Flora of Tropical Africa":D, mespiliformis, Hochst. A shrub or tree 6-6o feet high or more; wood compact, often black in the middle. Young shoots and inflorescence ferruginous-tomentose,
leaves oblong or elliptical 2-6 inches long, -2j- inches wide, at first pubescent. Flowers white, dicecious; inflorescence axillary, short. Male flowers few or many together 5 (or 4) merous; calyx hairy on both sides, lobes ovate or lanceolate; corolla urceolate-oblong; stamens io-i6, often in pairs; ovary rudimentary, hairy or wanting. Female flowers solitary or 3-1 together 5 (or 4-3) merous; staminodes 6-8 in i row, ovary ovoid or conical, silky, terminated by 2 short hirsute bilobed styles, 4 or 8-celled and ovuled. Fruit sub-globose 2-1 inch diameter, 4-5 seeded, edible. Albumen somewhat ruminated. Tete, Senna, Laputa, and other parts of Tropical Africa. Moraes (Manual Practico de Agricultura), who describes it as a small tree with excellent timber, gives its names in Angola as, 2, Silviera or
Musolviera; 17, Mulende, and in Zambesia, 16, Hourabassa.
Mr. Burtt Davy (Kew Bulletin No. 4, 1908) gives several Transvaal localities, as also Mathibis Kom inter Lourenco Marques et Komati River Drift, Aug., 1886, arbor 40-50 pedalis, Bolus, 7847," and states "Common in the Eastern middle veld of the Zoutpansberg; between 2000-2500 ft. alt. a conspicuously large tree with dark foliage, usually occurring on ant heaps in grey soil. Fruit eaten by Kaffirs." This probably yields part of the black-hearted timber produced in most
parts of the Province and known as Ebony, which should have an export value.

So far as I find it is undescribed, but in the absence of flowers there is nothing
to show whether it be to Thalamiflore, Calyciflore or Corollatflore that it belongs. Sim 6109.
The name, io, Nadente, belongs to a large tree in the forests of Magenja da Costa apparently belonging to Ebenacex, with dehiscent fruits and flat valves arranged in a star. Sim 5834.

Calyx and corolla hypogynous, 4-cleft or parted; stamens 2, inserted in the corolla-tube. Ovary superior, 2-celled. Fruit a drupe, a berry, or a capsule. A small Family, in which is included Jasminaces. Several members have medicinal properties, the Olive is cultivated for its oil, the Ash is a well-known and valuable European timber, Black Ironwood is a Cape timber, and among garden-flowering shrubs are the Lilac (Syringa), Privet (Ligustrum), Jesmine (Jasminum), &c.
175. OLEA. Trees or shrubs having opposite, exstipulate, simple, entire coriaceous leaves, paniculate axillary or terminal inflorescence, and regular hermaphrodite flowers.
Calyx 4-lobed ; corolla with a very short tube and 4-parted limb, the segments valvate in aestivation; stamens 2, with short filaments, but slightly exserted. Ovary superior, 2-celled; ovules pendulous; style short; stigma capitate. Fruit a fleshy drupe, with a hard i-seeded stone, and albuminous seed.

most widely-known species.
O. verrucosa, Link. Vern. lizames-i, Wild Olive; 4, 15, Nguma; 6, in-saca-saca; 13, Um-quma. A tree 7-10 metres high, 30-45 c.m. diameter of stem, branched a
good deal and with little clean timber; sometimes much larger and more old and gnarled.

the appearance of a glabrous yellow surface, the upper surface and the twigs sometimes similarly clad at first and afterwards glabrous, in other cases almost glabrous from the first. Panicles axillary, trichotomous, not much branched, rather shorter than the leaves. Bracts deciduous. Fruit an oblong dry drupe about 6 m.m.
long, shortly pointed. I cannot by the description in Flora of Tropical Africa" distinguish O. chrysophylla, Lam., from O. verrucosa, except that the leaves of the former seem to be more regularly and densely coated with scales on the under surface, and to taper more toward each end. Frequent in some parts of the
M'Chopes ; also in the Maputa and Marracuene Lebombos, and in Natal and Cape Colony, where its durability ensures its use as a fencing pole.
It is probable that other Cape species of Olea occur in the southern districts but they did not come under my notice.
