HEPATICAE BOLIVIANA,
IN ANDIBUS BOLIVIE ORIENTALIS, ANNIS 1885-6,
A CL. H. H. RUSBY LECTAE.
BY RICHARD SPRUCE, Coneysthoipe, England.
The small collection of Hepaticae made by Dr. Rusby on the
eastern slope of the Bolivian Andes is an interesting addition to
our scanty knowledge of the Cryptogamia of that region. It
serves also for comparison with what we know of the hepatic
flora of the Peruvian and Quitenian (equatorial) Andes, investi-
gated by myself; of the Andes of New Granada, by Lindig and
others; and of Mexico mainly by Liebmann. One curious fact
brought out by that comparison is the greater correspondence of
the hepatic flora of Bolivia with that of Mexico than with that
of the equatorial regions (lat. 0--7 S.) personally known to me.
The climate and other conditions of growth in Mexico, a little
within the northern tropic, may be more nearly conformable to
those of Bolivia, in proximity to the southern tropic, than in the
intervening portions of the Cordilleras. Anyhow, many of the
hepatics of the highlands of Mexico are identical with those col-
lected by Dr. Rusby at nearly the same altitude in Bolivia, and
some of them were nowhere seen by myself near the equator.
Of Plagiochila, for instance, at least three Mexican species which
I did not gather in the Andes are proved to belong also in Boli-
via; and two other Bolivian species which I suppose to be new
have in Mexico their two nearest allies, neither of which is known
to exist near the equator. Lepicolea ochroleuca, N. (Sendtnera,
Syn. Hep.), a large and showy hepatic, grows rarely from Mexi-










co to the Falkland Isles, and now Bolivia is intercalated in its
range; yet I never fell in with it. Fewer Bolivian species than
might be predicated are identical with those of Chili or of South
Brazil, but further researches may add to their number.
In the following catalogue the genera stand in nearly the same
order as in my Hepaticae Amazonicpe et Andinae,' and I add a
few prefatory remarks on some of the more notable genera and
species.
A peculiar feature in the hepatic vegetation of Bolivia seems
to be the paucity of species of Frullania, as contrasted with their
great abundance and variety in the Equatorial Andes. They are
such conspicuous plants, from their habit of forming large, shin-
ing, reddish-brown or lurid-purple patches on trees and rocks,
that, if existent, they could not have been overlooked. Yet one
species must have occurred in some quantity, as it forms the bulk
of three of Dr. Rusby's packets; it is also new (F. Boliviana,
n. sp.) and differs from its nearest ally, F. tetraptera, Mont., in
the dioicous inflorescence and other important characters specified
below. F. tetraptera was discovered by d'Orbigny in Chili, and
a small fertile specimen has been picked out of Dr. Rusby's So-
rata collections by Mrs. Britton. The remaining species are all
in small quantity, but comprise some novelties, which will be
described in their place.
The headquarters of the vast genus Lejeunea is in the hot,
damp forests of equatorial plains. In the Quitenian Andes there
is a considerable falling off in the number of species when we
ascend above 4,000 feet, which is Dr. Rusby's lowest limit for
hepatics in the Bolivian Andes. Three of his Lejeunea are in
considerable quantity: L. (Omphalanthus) fliformis (Sw.); L.
(Taxilejeunea) isocalycina, in broad, milk-white patches, rarely
fertile; and a Ceratolejeunea which I have called L. fastigiata, n.
sp., from the long, sub-simple stems growing in closely-packed
bundles. Tropical ferns afford a prolific nidus for the minuter
Lejeunea. On an Acrostichum gathered by Dr. Rusby grow,
besides an undescribed Radula, some half dozen Lejeunee. One
of these, Ceratolejeunea malleigera, n. sp., is the gem of the col-
lection. It is abundantly fertile, and its most striking peculiarity
is in the perianth being produced upward into two mallet-like










horns, that remind one of the antenna of some tropical moths.
Lopholejeunea Rusbyi, n. sp., is one of the larger species, and is
fortunately in perfect state. Like its congeners it has the keels
of the perianth bordered by a broad toothed wing, but in the
acuminate serrated leaves it differs from all others. Most of the
remaining Lejeunea are parasitic on other hepatics, and (with the
exception of L. denticulata) are in small quantity-some indeed
so scanty and imperfect that I do not venture to name them. Of
those I recognize, the majority extend through tropical America
to the Antilles and Mexico.
Radula are few and in small quantity, but include two new
and very interesting species, and (what I was particularly pleased
to see) good specimens, though sterile, of the true R. Xalapensis,
Mont., which was so-named by Montagne from a site called
Xalapa on the eastern side of Bolivia, and not from the famed
Mexican city. Radulae, like Lejeune, are apt to grow much
mixed up, and it was doubtless a specimen of R. ramulina, Tayl.
which Gottsche received from Montagne under the name R.
Xalapensis (having lurked undistinguished in the same tuft with
the true plant) and described as such in Mexikanske Levermos-
ser." A stem or two of R. ramulina occurs attached to several
of Dr. Rusby's Plagiochilte: it is well distinguished from R.
Xalapensis by its larger size, and especially by the abnormally
large and overlapping lobule, in which it closely approaches the
Irish R. voluta, Tayl.
Scapania Portoricensis, Gottsch. This, the only tropical
American species of its genus known to me, and certainly one
of the noblest, was gathered by myself in perfect fruit, growing
on wax-palms in the forest of Canelos (June, 1857) and named
in my MS. Scapania splendid, but not published until 1885. I
did not even at the latter date know of the existence of a memoir
on the Hepaticae of Porto Rico, by M. M. Hampe and Gottsche,
published so long ago as 1853, in which the same Scapania is
described, but from barren specimens, and with the erroneous
character of a quite entire lobule. Dr. Rusby gathered in Boli-
via a single very fine plant of it, and I have picked fragments of
the same off some of his other hepatica; but in these, as in
others in Porto Rico and Jamaica (Scap. grandis, Bosw. in Journ.










Bot.) and in my own from Ecuador, the lobule is invariably finely
toothed all round.
Isotachis serrulata, Sw., is one of the most conspicuous of
hepatice from its size, its purple or blood-red color, and its habit of
forming wide, dense patches, rarely with any admixture of other
species. It is well represented in Dr. Rusby's collection, and we
have it also from south Brazil and the Antilles, yet I was never
fortunate enough to fall in with it.
The solitary species of Herberta (= Sendtnera, Syn.) differs
from all others known to me by the serrated laciniae of its deeply
bifid leaves.
Bazzania is represented by four species, three of which have
been previously found in Chili, New Granada, etc. B. Rusbyi, n.
sp. is a very pretty species, notable for its pellucid foliage, its
underleaves sharply spinuloso-dentate, etc. The Mexican B.
denticulata, L. et G. is possibly its nearest congener, but is
smaller, more opaque, and the underleaves are much less toothed,
especially at the sides. In a genus where the numerous species
are separated by such minute characters, two equally conscien-
tious observers will often differ as to which are species and which
varieties.
Of the five Lepidozia? in the collection, two exist in some
quantity, and were probably abundant. The one is L. plume-
formis, nob. in R6v. Bryol. (1887) previously known to us only
from scanty specimens gathered in south Brazil by Glaziou; the
other is the widely-distributed L. cupressina (Sw.), which (as L.
lumidula. Tayl.) extends as far north as the British Isles. A
third Lepidozia, of which there are but few specimens, is a variety
of L. truncatella, Nees, whereof the type is south African. Al-
though the identity of an African with an American hepatic is
to be admitted with caution, we have a few undoubted examples
of such, e. g. Lejeunea trifaria, N. and L. Sagracana, Mont.
Plagiochile constitute the bulk of Dr. Rushy's collection.
They are in greatest variety in the sections Spinulosae and Fron-
descentes, and they include a fair share of novelty. A Plagiochila
near the common P. asplenioides of the north temperate zone,
yet well distinguished, is the P. alternans of Gottsche, still
known only in barren state. Although Dr. Rusby's specimens










extend its range from Mexico to Bolivia, and Mrs. Britton sends
me the same, gathered by Mr. Hyde in Costa Rica, I never met
with it in so much of the intervening space as I traversed.
In contrast with the abundance and variety of the Plagiochile
Grandifoliae in the Quitenian Andes is their paucity in Bolivia,
only two species being clearly distinguishable. Yet one of these,
P. Notarisii, notable for its large, flattish, semi-cordate, pauci-
dentate leaves, seen by me in small quantity only in the valley
of the Pastasa, has been gathered abundantly by Dr. Rusby.
Of the numerous species of the section Cristatae I gathered
in Amazonian and Andine forests Dr. Rusby's collection includes
not one; but it has two other species, quite distinct from any of
mine, whereof one had been previously discovered in Bolivia by
d'Orbigny. The other (P. Boliviana, n. sp.), which I suppose
to be new, comes very near the P. punctualis, G., found by
Liebman in Mexico.
Lophocolee, with a single exception, are exceedingly rare.
Of the sections Bidentatae and Bicornutae, so abundant in equa-
torial forests, fragments only of one, or possibly two species have
been seen. But one other species, notable for its oblong-hexa-
gonal leaves, with a ciliiform tooth at each of the four free angles
(whence my name, L. 4-dentata, n. sp.) must have abounded,
for it exists intermixed with nearly every other hepatic.
Of.Jungermania there is only a single species, but it is new
and very interesting. In the long sub-simple stems and the
laterally accumbent roseate foliage, it might seem a slender form
of J colorata, from which it differs essentially in the opposite (not
alternate) leaves, scarcely at all decurrent at the base. Unfor-
tunately I found no perianths, though I sought for them sedulously.
The remaining genera are for the most part sparingly repre-
sented. There is one example of the anomalous genus Notero-
clada (N. arhiza, n. sp.)-anomalous also as a species, from be-
ing almost utterly rootless, whereas its congeners have of all
leafy hepaticas the longest and strongest radicles.
There are luxuriant specimens, both 8 and 2, of Marchantia
chenopoda, L.; and Dumortiera hirsuta, N., vindicates its claim
to be a cosmopolite by appearing in very nearly the same form
as the Irish variety (D. irrigua, Tayl.).

in very small quantity, but fertile, on the upper Rio Negro. In
Bolivia, however, it was gathered by Dr. Rusby at all his stations,
growing sparingly, intermixed with other hepatics, and always
sterile.

The R. Xalapensis described by Gottsche in 'Mex. Lev&rm.'










is an entirely different plant, viz. the R. ramulina, Tayl., which
stands next to the Irish R. voluta, Tayl. Dr. Rusby gathered the
true R. Xalapensis at Yungas (alt. 6,000 ft.), No. 3,034, and R.
ramulina occurs sparingly in several packets of his collection,
mixed mainly with Plagiochil ; but his R. Xalapensis is accom-
panied by a new and very distinct species of the same genus (R.
clavulata, Ms.) which has the rare peculiarity of a monoicous
(autoicous) inflorescence, the great mass of the genus consisting
of purely dioicous species.

L. CUPRESSINA (Sw). Yungas; Mapiri, cum Orchideis, etc.
(Nos. 3,026, 3,064, 3,070, 3,07I). Agrees well with an original
Jamaican specimen from Swartz. Grows in wide depressed tufts,
very much as L. reptans does with us. Leaves have sometimes,
but very rarely, I-3 rudimentary teeth at antical base. Near in-
sertion of a branch a six-cleft underleaf is occasionally seen.
Lacinie of both side leaves and under leaves are simply subulate,
rarely with the slightest acumination. But in the Peruvian L. ten-
uicuspis (= L. cupressina var. tenuicuspis, Hep. A. et A.) all the
leaf segments end in a slender cusp of a single row of cells-in
the underleaves as much as 6-9 cells long. From this and some
other differences I prefer to regard it as a distinct species, under
the MS. name (L. tenuicuspis) proposed in 'Hep. Am. et And.';
especially as I have seen no intermediate form from any country.

3,o 16; 3,02 1, 3,047 pro parte).-Some of these forms, notably Nos.
3,012, 3,013 and 3,021, approach the West Indian "P. superba,"
but are hardly separable from typical P. adiantoides ; and the
" P. superba" gathered by d' Orbigny "in Bolivize locis udis
silvarum inter Chupe et Yanacache doubtless belongs to the
same category. The original P. superba, founded by Nees on a
plant gathered in the Mauritius by Sieber, however, seems dis-
tinct.

The three forms described in Hep. Am. et A., distinguished
namely by differences in the breadth of the leaves and in the
degree of marginal dentation, belong to but one species. The
toothing of the anterior margin is variable but never entirely
disappears (as asserted by Lindberg). The presence or absence
of a wing to the perianth is inconstant in all the forms.
PLAGIOCHILA ( HETEROMALLE) IMPLEXA, L. et G. Hep.
Mex. 76, t. XIII. Dr. Rusby gathered this species, mixed with








184


Herberta serrata, n. sp. at Unduavi (alt. o0,000 ft.), but only the
male plant. It belongs to the Heteromalle, and agrees well
with the description and figure in Gottsche's work. The leaves
are smaller than in most of its congeners (I.2x I.omm) strongly
second and accumbent, suborbicular, but with the whole antical
margin so strongly revolute that they seem almost dimidiate.
The rounded, plane, postical margin is closely spinuloso-dentate,
teeth about 20. Cells minute and opaque, thick-walled and sub-
equilateral, but near the axis in the lower half less minute and
twice as long as broad. 5 spikes medial and terminal, ovato-
fusiform ; bracts monandrous.
Liebmann discovered this species on the volcano Orizaba, at
8 to 12,000 feet, or at nearly the same height as Rusby found it
in the Bolivian Andes.

mens, although very few, possess good perianths, which were
wanting in those I took as the type of the species, I add a brief
description. As in the plant of Ecuador so in that of Bolivia,
the leaves rapidly discharge their yellow coloring matter on
being steeped in water, and remain quite bleached.

(No. 3,005 p. p.)-The few species previously known of this
curious genus are notable for their numerous, long, thick radicles,

exactly accords with the other species in the character of its
foliage, the sterns are either entirely rootless or shew rarely one
