LANKESTERIANA 18(3): III. 2018. EDITORIAL A PAPERLESS JOURNAL, BUT STILL ON PAPER NEVERTHELESS FRANCO PUPULIN Lankester Botanical Garden, University of Costa Rica. P.O. Box 302-7050 Cartago, Costa Rica firstname.lastname@example.org Since immemorial time, humanity has expressed its desire to transmit ideas, emotions, concerns, and knowledge, in a manner that could be conserved through time. This legacy has been shaped in the form of documents, recorded on a wide range of media: fabric, parchment, and paper. We are now witnessing the passage to the multi-media era, where information is output in the form of pictures, movies, sounds, texts or a combination of these, stored in a plethora various kinds and sizes, CD and DVD ROM, internal and external hard disks, and others electronic media. Some of these media have already passed away, and no equipment is currently available to read and interpret the content stored in their memory. Post-Linnean botany has been mostly perpetuated through books, journals, leaflets, and herbaria, and paper has proven to be a pretty effective medium for conserving the information. Libraries and plant museums have guaranteed unconditional access to this information. The validity of paper as the best storage medium, both from the point of view of efficiency and environmental impact, has however been put into question in the last two decades (Conway 1996). Let we discuss these two points separately. Preservation is not a matter that applies to challenges for the preservation of data as well, and the risk of loss is probably higher than in most other preservation functions (Conway 1999). Nevertheless, the principles of digital preservation are the same as those of the analog world and, essentially, aimed at extending the useful life of information resources. In some cases, however, the basic conservation principles of longevity, choice, quality, integrity, and access, have shifted in priority and actors. Traditionally, preservation of the information involved a complex, physical work aimed at perpetuating the integrity of the sources through the active control of external and internal factors of deterioration (stabilizing and maintaining temperature, humidity, light exposure, pollution, dirt, dust and mold, surveying handling techniques and security, adopting digital world, preservation is less concerned for the longevity of the storage media, but is much more dependent on the life expectancy of the access system to retrieve the data stored on them. For this reason, most libraries simply do not physically store electronic publications. Even though a study by Shipman et al. (2011) unequivocally shows that to destructively digitize documents in-house (disposing of the physical it is several hundred percent more expensive than physical conservation. So, the libraries e-journals, e-books, databases and so on, are linked to from their catalogues, but stored elsewhere. Where? Usually, on the publishers own website. In the past, the active role of the publisher ended when the book or journal or whatever kind of printed matter was released and dispatched. From this moment on, the responsibility of its conservation as a tangible item, and the preservation of the information stored in it, was passed on to the individuals, libraries, archives, museums and other subjects who owned copies of the publication. In the digital world, this responsibility remains mostly assigned to the publisher. So, this poses a basic question to Lankesteriana Are we ready, from the point of view of the knowledge,
LANKESTERIANA 18(3). 2018. Universidad de Costa Rica, 2018. II LANKESTERIANA the protocols, the human and IT resources needed, to be entrusted as the main conservators of the information stored in our journal, in an exclusively virtual, intangible, digital format? Last month, in only two consecutive days, we lost two of the three external disks (in addition to the two servers) where the history of Lankesteriana is preserved. None of us, is a specialist in computer science, and even less in the theory that must undoubtedly exist on the best practices of preservation of digital information. We have already replaced the two damaged disks, but not system. Simply said, we are not ready to go completely paperless and we do not know when we will be. On the other side, the environmental issues associated with paper and digital media have occupied a large part of the debate on migration from traditional to electronic storage. They both do present common environmental issues including the extraction of materials, the use of huge amounts of energy and water for their production and transportation, and their transformation into waste throughout their life cycle. Whilst the use of paper seems to be more environmentally questionable during the production stages (but the organization representing the paper and print industry claims that the paper-making process is sustainable), digital media are particularly they contain toxic materials including lead, mercury, trioxide, polyvinyl chloride, and phthalates. A study by Toffel and Horwath (2004), comparing the reading of newspaper content on a personal digital assistant vs the traditional way of reading a newspaper, and the wireless teleconferencing vs business travel, shows that for both cases wireless technologies create lower environmental impacts. On the other side, Bull and Kozak (2014) argue that the context of the information and communication technology will continuously impede the ability of the the Life Cycle Assessment methodology to measure its products to be compared with the environmental footprint of paper media. Our assumption that digital is greener than paper could still be based on unsubstantiated claims. As the main reason for physically distributing Lankesteriana aside from improving its visibility, is to augment the probabilities of its forever conservation, we decided to remove from the mailing list of the journal all the individual subscribers, who obviously play no role for this purpose, including the authors themselves, who have so far received a physical copy of their publications. This also includes the numerous research libraries which, over the years, have shown their interest in essentially converting into repositories of digitized information, and therefore no longer require a physical copy of the journal to be placed on the shelves, and those organizations that the Costa Rican laws of printing assumed as obligatory recipients but were recently downgraded to digital users. Coherently, Lankesteriana will no longer accept individual subscriptions, which will be reserved exclusively for those public libraries that wish to offer a form of Cleaned of individual subscriptions and libraries no longer interested in receiving physical copies of the mailing list of Lankesteriana will be reduced to 280 copies, including the copies to be used for interchange and those printed for the journals physical archives and intended to replace any copies lost or damaged during shipment.

However, they are unable to store nutrients in the embryo and often rely on fungi (predominantly imperfect Rhizoctonia spp.) in order to germinate (Arditti & Ghani 2000, Brundrett et al. 2003, Rasmussen 1995). When fungi colonise orchid seeds, they grow as intracellular tightly coiled hyphal pelotons and a symbiotic relationship is established (Huynh et al. 2004). In this symbiotic relationship, fungi supply the orchid with nutrients including nitrogen (Girlanda et al. 2011) and phosphorus (Cameron et al. 2007) while the Read 2006, Carbon utilisation by mycorrhizal fungi vary with some clades from the same Rhizoctonia species inhibited by sucrose (Wright et al. 2011) resulting in suboptimal seed germination (Huynh et al. et al. 2014, Wright et al. 2009). Some in vitro studies have successfully germinated orchid seeds asymbiotically (without fungi) using germination (Huynh et al. et al. 2014). Despite the germination success of asymbiotic plants, symbiotically germinated orchids established in soil better in the long term than those without fungi (Batty et al. 2001, Rasmussen 1995) which suggests fungal superiority and importance to orchid conservation particularly for plants that reside in depleted nutrient habitats. between species and different fungi are not equally effective in seed germination or growth (Phillips et al. 2011). Australian orchids generally have higher from other continents (Batty et al. 2001, Pandey et al. 2013, Phillips et al. 2011, Wright et al. 2009). Moreover, Rhizoctonia diversity in Australia is lower compared to other continents (Brundrett et al. 2003). Patchy fungal distribution in the soil, high fungal-host fungal selections (Wright et al. 2011) can lead to orchid rarity (Phillips et al. 2011) and is a considerable barrier for the conservation of endangered species, for example Caladenia huegelii (Swarts et al. 2010) and some other Caladenia spp. (Wright et al. 2010) but not others (Bailarote, Lievens & Jacquemyn 2012). some species whilst stimulatory for others (Brundrett 2007, Duncan & Coates 2010, Janes, Vaillancourt &

Pterostylis R.Br has over 400 species that are spread across Australasia (Phillips et al. 2014). Many of these species were described only recently and their et al. 2008). One representative, Pterostylis despectans (Nicholls) M. A. Clem. & D. L. Jones (Lowly Greenhood) is Duncan, Pritchard & Coates 2005, Janes et al. 2008, Marsh 2011), restricted to south east Australia (NSW Government 2018) and conservation efforts are required to mitigate its decline. This study investigated factors to improve germination for reintroduction based on success from other orchid genera. The aim was to determine water on protocorm development; and the effect of Materials and methods Seed collection and preparation Germination was performed on 8 year old dried seeds of P. despectans collected in Talbot (Victoria) on January 2006 from seed capsules of six random plants. The seeds were surface sterilised for 1 min in 0.5% NaOCl with one drop of Tween 20 (Fisher BioReagents ). Seeds were spun at 13 ,000 rpm for 30 s and the supernatant was removed with a sterile glass pipette. Seeds were trice rinsed with sterile milliQ water and the supernatant removed. Fungal isolation . Three collars were collected in situ during the growing season in July 2013 from a population in Bung Bong state forest (Victoria). The collars were cleaned under running tap water, surface sterilized with 1% NaOCl for 3 minutes and rinsed trice with sterilized were sliced into 1 mm longitudinal sections in sterile MilliQ water under sterile conditions. The pelotons were observed with a dissecting microscope, scraped out, dispensed in sterile MilliQ water and droplets containing pelotons were plated onto fungal isolation medium (FIM 0.3 g L -1 sodium nitrate, 0.2 g L -1 potassium dihydrogen orthophosphate, 0.1 g L -1 magnesium sulphate, 0.1 g L -1 potassium chloride, 0.1 g L -1 yeast extract, 5 g L -1 sucrose, 10 g L -1 agar, prepared to 1 L with deionized (DI) water, pH adjusted to 6.8 before autoclaving (20 min at 121 C, -2 ) (Clements 1981). Isolated pelotons were grown for 48 h at room temperature and scored as 1) Rhizoctonia no growth (Huynh et al 2009). Fungal growth and smoke water . Rhizoctonia fungi were transferred onto malt agar medium (MAM) mL L -1 ) and labelled as collar number (1) and a letter representing separate fungal isolates from each collar. Each plate contained triplicate plugs from the same and their growth was measured using a digital calliper symbiotic germination plates containing autoclaved oatmeal agar (OMA). Symbiotic germination. OMA (2.5 g L -1 ground rolled oats, 0.1 g L -1 yeast extract, 8 g L -1 et al 2014) was prepared in sterile petri dishes with three concentrations (0, 0.1 and 1 mL L -1 or presence (10 g L -1 ) of sucrose (Sigma Aldrich) before sterilization. One cm 2 squares of sterile Miracloth (Calbiochem, USA) were placed onto set OMA. One droplet of surface sterilised seeds was released onto each Miracloth square and a fungal square was placed in the middle of each plate. Nine fungal isolates were used for each of the six media types. One plate per treatment was not inoculated and was used (Si

Seed changes were scored as 1) dormant unchanged, 2) swollen, 3) protocorm and 4) protocorm with green leaf primordium (Fig. 1). Data analysis. Data was tested for normality and using Levenes test for equality of variance and was the above assumptions were transformed to normality. Normal data was analysed for statistical differences by test for homogeneous data and Games-Howell post-hoc for non-homogeneous data. Abnormal data was tested statistical software (version 23). Fishers family error test was performed using Minitab (version 17). Results Effect of smoke water and sucrose on germination. Symbiotic germination for P. despectans was low with the majority (94%) of seeds unchanged and positive effect on seed germination produced more than double the number of primordia stages. The highest germination was observed in media without and 1.0 mL L -1 particularly for protocorm and primordia stages. Although swollen seeds were noticeably changed from from 0.0 to 0.1 mL L -1 but decreased from 0.1 to 1.0 mL L -1 1. Pterostylis despectans seeds at different stages of germination. A. Dormant. B.

The greatest overall radial growth was in isolates from plant 3 and the least from plant 2. These patterns did plant 1 that had middle range radial growth. Discussion Germination. Pterostylis despectans seed in this study had very low germination success compared to other orchid genera. For example, other Australian orchids showed high germination that reached up to 100%, including more common Pterostylis species (Batty et al 2006, Huynh et al et al 2014). This low germinability may indicate requirements for additional stimulants and be a contributing factor to its rarity and consequent endangered status of P. despectans There are several other reasons that cause low germination numbers: seed age, post-harvest seed storage conditions and fungal Pterostylis despectans seed were collected 8 years prior to the experiment and may be too long for the optimum viability to be maintained. Studies on other plants have shown that time affects seed viability (Merritt et al 2003) with high orchid seed germination achieved when seed material was obtained within a year before germination (Batty et al et al 2014). Seed viability of Australian plants was affected by relative humidity and temperature during storage (Merritt et al 2003). Pterostylis sanguinea had et al 2014), and the higher incubation temperature used in this experiment at 25C may have restricted the full germination potential of the species. Australian orchids are often colonised with more than one taxa of endophytic fungi (Dixon & Tremblay 2009, Rasmussen et al. 2015) which explains why fungi different effect on seeds (Fig. 3). Other studies found no correlation between fungal taxonomy with germination et al. 2010) and could indicate other factors contributing to varying seed responses. Pterostylis orchid species varies between the plants rather than within one plant despite morphological and genetic similarities (Huynh et al 2009). Complex comparisons such as gene-environment interactions and metabolomic studies may provide more useful answers and direct future conservation efforts such as in situ inoculations to rejuvenate fungal diversity to improve germination and growth. Symbiotic fungi were essential for P. despectans seed germination but highlighted that other factors may be important for improved germination and survivorship of this species. High and successful asymbiotic in vitro germination can be achieved to rival or exceed symbiotic germinations beyond 93% (Bustam, Dixon & Bunn 2014) and may be the only alternative for similar P. despectans that have fastidious requirements for both the fungal partner and seed. radial growth (mm) of nine isolates from P. despectans L -1 0.1SW=0.1 mL L -1 1SW=1.0 mL L -1 ).

This result translated into an ecological conservation context would mean that copious volumes of viable seed is required to replace existing populations and even more for the expansion of populations which is not sustainable for the longevity of the species without water as a stimulant also resulted in low germination rates on an African orchid, Ansellia africana (Papenfus et al. 2016) with <19% at stages 4 of development, future research, especially highly endangered species that have low germinabilit y. The effect o f sucr ose on germination. Sucrose had an adverse negative effect on P. despectans seed germination. Similarly, the addition of sucrose decreased the germination of Caladenia species (Wright 2007, Wright et al 2011) resulting in the omission of et al 2014). On the other hand, some other orchid species ( ) grew better with the presence of sucrose (Huynh al 2004, Wright et al 2009) especially those germinated asymbiotically (Huh et al 2016) so there is a need for individualised ingredients to cater for the preferences of both orchid and fungus. In the presence of sucrose, fungi dominated and outcom peted seeds for nutrients and thus negatively affected seed germination. The fungi in sucrose media were morphologically different with more vigorous dense growth and covered orchid seeds. Similarly, it was observed that high concentrations of sucrose encouraged parasitic fungal growth whereas lower concentrations of sucrose promoted symbiotic associations in Dendrobium chrysanthum (Hajong, Kumaria & Tandon 2013). In contrast, other studies on C. tentaculata found no changes in hyphal growth or dominance regardless of sucrose presence (Wright et al. 2011). They found that individual fungal isolates due to fungal isolates belonging to different taxa (Wright et al. 2011). Fungal isolates from P. despectans may also have different requirements and responses to carbon utilisation and assimilation. This may also stimulate or exacerbate fungal functionality in situ under extreme events. The effect of smoke water on fungal growth. These growth (Jasinge 2014, Zagory & Parmeter 1984). toxic to fungi and inhibit fungal growth by altering the et al 2012) suggesting that fungi from P. despectans had higher tolerance to phenolic compounds. The varying fungal tolerance to phenolic compounds is thought to be due to the quantity or quality of enzymes (laccases) that metabolise these toxins (Jasinge 2014, Zagory & Parmeter 1984) and symbiotic fungi.

(Karremans 2016). New species are being discovered frequently (Jrgensen & Leon-Yanez et al. 2017, Pupulin & Bogarin 2012). Some species in the genus show a wide distribution range while others are endemic to restricted localities (Baquero 2018, Moreno et al. 2017). Species of Lepanthes are recognized by the ramicauls enclosed by commonly ciliated lepanthiform sheaths, the petals that has a body which connects to a pair of blades the base of the lip a small structure, present in most of has been traditionally used as a morphological trait which helps to distinguish among different species in the genus, and its importance in Lepanthes pollination Blanco and Barboza (2005). of lobes in the petals and the shape of the lip, can also help to distinguish among species in Lepanthes Based on the number of petals and lips lobes, some species of Lepanthes have received suggestive names, Lepanthes pentoxys Luer, Lepanthes hexapus Luer & Escobar, Lepanthes heptapus Luer & Escobar and Lepanthes octopus A rich species area of Lepanthes is located in Carchi province, Ecuador, very close to the limit with Imbabura and Esmeraldas provinces. In this region, a new species has been discovered. It is described and compared here with an informal group of species within the genus, that shares similar morphological Lepanthes tetrapus Baquero & J.S.Moreno, sp. nov. (Fig. 1). TYPE: Ecuador.

First published online: 29 October 2018 Licensed under a Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Costa Rica License doi Introduction Trichocentrum undulatum (Sw.) whose distribution extends from Jamaica, Cuba and in southern Florida is the northernmost limit of the species and is the only mainland North American population. In southern Florida, T. undulatum is rare and only found in a restricted area of coastal salt marsh found growing only on buttonwood trees ( Conocarpus erectus L.). This Florida population is Melanagromyza miamensis Spencer. Such herbivory has not previously been reported beyond southern The dipteran genus Melanagromyza (Agromyzidae) consists of over 300 species and is within plant tissues (Spencer 1990). Herein we report T. undulatum observed in four provinces within Cuba (Artemisa, Cienfuegos, Matanzas, and Sancti Spiritus). Methodology Trichocentrum undulatum can be found within every province of Cuba, in different habitats, and growing on a diversity of phorophyte hosts. Four populations of T. undulatum were visited in Cuba in the provinces of Artemisa, Cienfuegos, Matanzas, and Sancti Spiritus during the summers of 2016 and 2017. Transects were laid out within forest of four transects were made at four wild populations in the Artemisa (one transect) and Matanzas (three evaluated and collected for herbivore presence at Macradenia Orchid Garden in Cienfuegos province and Comunidad 23 Orchid Garden in Sancti Spiritus province. For every T. undulatum plant encountered on the transect, a search for other plants was made within between 20 to 100 meters, depending on the forest
LANKESTERIANA 18(3). 2018. Universidad de Costa Rica, 2018. 190 LANKESTERIANA holes were examined and any pupal casings found were photographed. Results T. undulatum was captured, larval casing characteristics were used to determine that the herbivores affecting T. undulatum within Cuba are a Melanagromyza species. Pupal casings were extracted the description of the genus Melanagromyza by having two sclerotized plates with pronounced bulbs atop the plates with a protruding horn in the center (Fig. (Scheffer pers. comm. 2017). Exit holes found on the southern Florida population (Fig. 2). No other Diptera or fruits of T. undulatum A total of 391 plants were located in the transects between the 2016 and 2017 surveys. Of these, 149 Melanagromyza sp. presence was 48% (72 plants). The number of dipteran casing presence. Melanagromyza sp., we observed fruit in both 2016 (two fruit out of holes and boring architecture were deposited at the Onaney Muiz National Herbarium from the Institute of Ecology and Systematics, Havana, Cuba. Discussion T. undulatum by an nature of the Agromyzidae family (Spencer 1990), it is possible that the observed Melanagromyza in Cuba is the same species as that found in southern Florida, but this requires further taxonomical study by a specialist. Melanagromyza sp. has only been observed in the T. undulatum and not on any other orchid species in the surrounding areas assessed in Cuba and southern Florida (Borrero unpubl. 2017). In southern Florida, herbivory intensity by M. miamensis was 100% between 2014 and 2015 in the largest FIGURE 1.

With approximately 120 known species, the Philippines are considered as a center of diversity for this genus (Cootes 2011, Pelser et al. 2011). Given that most Dendrochilum species are restricted to cool, humid, and often exposed conditions in montane forests with an unusually high share of narrow endemism (Pedersen 2007a), it is believed that there are still a number species awaiting discovery and description, especially in Mindanao, as this island is composed of a number of high mountains which are relatively unexplored botanically ( e.g. Cootes 2017, Naive et al 2017). Fresh materials of an interesting but unknown Dendrochilum the section Platyclinis because of the synanthous and an apical wing on the column, was collected Bukidnon on the island of Mindanao in the Philippines in June 2017. After meticulous examination of its morphology and comparison with protologues and digitized type specimens of Dendrochilum sect. Platyclinis species from the Philippines (JSTOR 2018) and neighbouring countries, we found the material matches with Dendrochilum warrenii H.A.Pedersen & at the European Orchid Conference in London by Blair Sibun (Pedersen et al 2004). It was then described by Pedersen and Gravendeel in 2004 based on a specimen in cultivation provided by Richard C. Warren (after whom the species was named), with unknown provenance. Based on moleclar phylogenetic analyses, these authors hypothesized that the species could be originating from the Philippines and/or Sulawesi (Pedersen et al 2004, Sulistyo et al 2015). D. warrenii origin. An extended species description based on this knowledge is provided together with color photographs Materials and methods Fresh plant material was collected during a botanical excursion in June 2017 in the Bukidnon province of the island of Mindanao in the Philippines. A spirit collection was deposited in the

Our descriptions of vegetative and reproductive characters are based on living plants and the spirit collection. The species description follows the style of Pedersen (2011) using general plant terminology of Beentje (2016). Below, we provide a detailed description and colored photographs as well as notes on the distribution, phenology, and ecology in the wild.

Presl, Epilyna Schltr., Sertifera Lindl. & Rchb.f, and Sobralia Ruiz & Pav. (including Brasolia (Rchb.f.) Baranow, Dudek & Szlach.) (Neubig et al 2011, Chase et al 2015, Baranow, Dudek & Szlachetko 2017). Orchids of the genus Sertifera have relatively small Elleanthus Vegetatively, Sertifera like Elleanthus and Sobralia are caespitose plants with slender, elongate cane-like stems and plicate leaves. However, Sertifera is easily distinguished from the other genera of the tribe by having leaf sheaths with tubercles, axillary peduncle. Lindley and Reichenbach (Reichenbach 1877) described Sertifera with two species: S. purpurea Lindl. & Rchb.f. from Ecuador (with lateral corymbose S. virgata Rchb.f. from Peru (with was transferred by Schweinfurth (1938) to Elleanthus The second species of Sertifera from Ecuador, was described by Kraenzlin (1899) but hiding under the name of Diothonea lehmanniana Kraenzl. (transferred to Sertifera by Garay in 1978). Schlechter (1920, 1924) then described three species from Colombia: Sertifera colombiana Schltr., S. major Schltr. and S. Schltr. Subsequently, Williams (1939) and Schweinfurth (1946) described two more species from the same country: S. grandifolia L.O.Williams and S. aurantiaca C.Schweinf., respectively. Recently, another three species have been proposed for Colombia: S. gracilis Rchb.f. ex Szlach. & Baranow, S. risaraldana Szlach. & Baranow and Szlach., Kolan. &. MedinaTr., (Szlachetko & Baranow 2014, Szlachetko, Kolanowska & Medina Trejo 2014). Thereby, at the moment ten species are referable to Sertifera Sertifera has been referred as a genus restricted to the northern Andes, species have been reported from Ecuador, Colombia, and Venezuela between 1,000 and 3,600 m of elevation (Schlechter 1924, Szlachetko & Baranow 2014). the presence of populations of S. purpurea ; which

In Peru, it is known in the Departments of Amazonas and San Martn, between 2,150 and 3,053 m elevation (Fig. 4). HABI T A T AN D ECOLOGY : Plants of this species were found growing in shrub vegetation with small trees up to 5 m tall, dominated by Podocarpus oleifolius D.Don ex Lamb., Clusia sp., Weinmannia sp., Miconia sp., and Myrcia sp., and open areas with herbs and small shrubs (Fig. 2C). Individuals with October. Sertifera purpurea and S. lehmanniana were described based on plants from the north-central Andes of the Ecuador. The type specimens of S. purpurea were collected in the Province of Tungurahua ( Spruce 5394 ) and the Province of Pichincha: Quito ( Jameson s.n .) and in the Valley of Lloa ( Jameson s.n .). The type specimen of S. lehmanniana was collected in the Province of Pichincha: west of Cerro Corazon (south of Quito), near Canchacoto ( Lehman 126 ). Both species display similar morphological features. Based on examination of the herbarium specimens (digital of S. lehmanniana (microscope slide prepared by Garay, HUH-82476), the feature that distinguishes S. lehmanniana from S. purpurea displays ovate-oblong to ovate-ligulate petals ( vs ovate-elliptic to subrhombic). Dunsterville and Garay (1966) considered that they both represent the same species and placed S lehmanniana as synonym of S purpurea ; we agree with that assessment. Sertifera colombiana is also similar to S purpurea (Schlechter 1920, Mansfeld 1929, plate 13, nr. 46); however, additional research is necessary to state whether they are the same species.

Within Pleurothallis R.Br. as circumscribed by Pridgeon et al (2005), subsection Macrophyllae Fasciculatae Luer represents the largest taxonomic group with between 236 and 305 described species, depending on synonymy (Wilson, unpubl.). A consistent characteristic among all the species of Pleurothallis subsection Macrophyllae Fasciculatae described to date, without exception, is a prominent and conspicuous labellum or lip Pleurothallis castanea Mark Wilson, G.Merino & Pleurothallis nangaritzae Tobar & Mark Wilson and Pleurothallis rubrifolia Mark Wilson, Tobar & Salas Guerr. by Wilson et al (2016). While the dimensions, morphology, texture are currently no described species of Pleurothallis in subsection Macrophyllae Fasciculatae with a highly reduced or apparently lip. Pleurothallis to be described Pleurothallis abortiva section or subsection within subgenus Pleurothallis Luer (1986) created section Abortivae to include P. abortiva P. abortiva from the section, rendering it monotypic. Luer (1998) retained the monotypic section and stated that P. abortiva is distinguished from all other species of the subgenus monotypic until Doucette et al (2016) described Pleurothallis kaynagata A.Doucette, Mark Wilson & Until recently, P. abortiva P. kaynagata Abortivae

Although Luer (2005) chose to combine subsections Macrophyllae-Fasciculatae and Acroniae under the resurrected name Acronia C.Presl., preliminary phylogenetic analyses indicate that the two groups are phylogenetically distinct (Wilson et al 2011, 2013).

EPONYMY : Named for the large, hairy spiders of which DISTRIBUTION : Scaphosepalum tarantula a few remaining forests near Las Tolas, not far from Quito, Ecuador, north-west of the city. HABITAT AND ECOLOGY S. tarantula were seen growing in a cloud forest, not far from remain in the diminishing forests at the same location. It grows at an elevation of ~1800 m a.s.l. as an ephiphyte and is sympatric with other orchids of subtribe Pleurothallidinae such as Scaphosepalum Luer, (Luer) Luer, Dracula (Luer) Luer, Luer & Hirtz, Luer & Hirtz and Platystele Luer. As with many other species in the genus, it grows in a very moist, low light environment, the zone. CONSERVATION STATUS : Even though a population of S. tarantula is still growing in the same area where it being cut down and about 80% of the original forest is now gone. Urgent actions are required to preserve this remaining forest since not only to protect this new species, but also a very rare species. Most of the plants of grow in nearby. Not far from where S. tarantula grows, some protected forest such as Bellavista, Mindo Nambillo or even Pahuma are being protected, nevertheless, in about ten years of searching for a new locality of S. tarantula by the authors, we were unsuccessful at Sca phosepalum tarantula is unique among the species of Scaphosepalum because of a particular combination of characters. The leaves suffused with the rhomboid petals and the pandurate lip with a shovel-shaped epichile distinguishes it from any other species in the genus (Fig. 1). This species has tails of the lateral sepals (Fig. 3). Nevertheless, the different shape of the lip and petals distinguishes both species. The rhomboid versus subquadarate petals and the pandurate lip with the epichile shovelshaped versus the elliptical-subpandurate, trilobed lip, separates S. tarantula from In S. tarantula some other features are different from any of the forms of including the slenderer apex of the dorsal sepal, and the tails of the lateral projecting to the front instead of projecting to the S. (Figs. 1). Although and S. tails as well, the plants (to 35 and 25 cm respectively) S. tarantula have a pair of lobes near the middle of the lip that are not present in S. tarantula The lip on has an obtuse epichile against the rhomboid epichile in S. tarantula In erae

THE ORCHIDACEAE OF PRIMITIAE FLORAE ESSEQUEBOENSIS (1818) CARLOS OSSENBACH Orquideario 25 de Mayo, San Jos, Costa Rica and Lankester Botanical Garden, University of Costa Rica firstname.lastname@example.org ABSTRACT The German botanist and Professor at the University of Gttinge n, Georg Friedrich Wilhelm Meyer (1782), studied the plants collected in the Dutch colony of Essequibo by Ernst Carl Rodschied and those kept in the herbarium of Professor Franz Karl Mertens, which he had received from a Dutch colonist during the early 1800s. On that basis, he published in 1818 his work Primitiae Florae Essequeboensis, science.

It was founded between the Essequibo River on the west and the Demerara River on the east, on the eastern border of the Spanish General Captaincy of Venezuela in the Guiana region. It formed a part of the settlements that are known under the collective name of Dutch Guiana. Essequibos FIGURE 1.

Essequibo and Demerara were captured by the British in 1781, then the colonies were occupied by the French until in 1783 the Peace of Paris restored the territories to the Dutch. The British occupied Essequibo again in 1796 and gave it back for a short time to the Netherlands as a consequence of the Peace of Amiens, from 1802 to 1803. After that it was again taken by the British during the Napoleonic wars. The British never left again and Essequibo became of London. Starbroek was renamed as Georgetown. The colonies of Essequibo and Demerara were merged into British Guiana. Georg Friedrich Wilhelm Meyer (1782) was a German botanist and Professor for Forestry at the University of Gttingen (Fig. 2). He had studied Forestry and Natural History between 1801 and 1805 in Gttingen and Dillingen and came in 1813 under employ of the Prussian Government as Forestry Inspector and then Director of Forests in Paderborn, Corvey and Hxter. He continued his studies in Gttingen and received in 1818 his Ph.D. It was at that time that Meyer became interested in tropical botany, especially after he had the opportunity to purchase the herbarium of Ernst Carl Rodschied (?). Rodschied was a German physician and botanist who had emigrated to Essequibo in 1790 in the service of the Dutch West-India Company and had lived there until his death in 1796. Rodschied wrote several small works about climate, social circumstances, and health problems of the population of the colony, and made frequent botanical excursions along the rivers Demerara and Essequibo (Baldinger 1796). Meyer was also fortunate to make the acquaintance of Professor Franz Karl Mertens (1764 1831), a botanist from the city of Bremen, who had a second collection of plants from Essequibo, which he FIGURE 2.

These he gave to Meyer on loan Based on both Rodschieds and Mertens collections, Meyer published in 1818 an important work, under the title Primitiae Florae Essequeboensis adjectis descriptionibus centum circiter stirpium novarum, observationibusque criticis (Fig. 3), in which 344 species of plants were described, of which 118 turned out to be new to science (Anonymous 1819a, 1819b, 1820). Five species of orchids are mentioned in Meyers Flora, among them two that were new to science: Cymbidium trinerve G.Mey. [= Cyrtopodium andersonii (L.) Lindl.], Oncidium emarginatum G.Mey. [= Dimerandra emarginata (G.Mey) Hoehne], new to science (Fig. 4), Epidendrum ciliare L., G.Mey, yet again a new orchid species, and Vanilla aromatica Sw.

LANKESTERIANA 18(3): 243 2018. BOOKS Rankafu. Orchid Print Album by Stephen Kirby, Toshikazu Doi & Toru Otsuka. Richmond, Surrey, UK, the Royal Botanic Gardens, Kew, 2018. Volume in octavo (19.5.3 cm), x, 289 pages, 250 illustrations in color, 31 black and white photographs. Hardbound. Special price at Kew Gardens, .00. Rankafu is a remarkable book, which tells the story of a remarkable set of Japanese orchid woodblock prints from the early 20th century, and through them the story of three remarkable men. Shotaro Kaga (1888), the eldest son of a wealthy family, was a banker and a pioneer horticulturist, whose work and collection helped to start an orchid craze in Japan that continues to this day. He built what probably was the best Japanese nursery of its times, taking advantage of the direct experience he had acquired through the acquaintance with renowned collections like that of the Royal Botanic Gardens, Kew, and with famous British growers like Sander in St. Albans, who he visited in 1910 and from whom he would buy hundreds of plants over the next decades. To ensure his plants were cultivated to their best, Kaga had them grown under the care of Kenkichi Goto (1895), who had been in charge of the Imperial Nursery of the Shinjuku Garden as a specialist orchid grower and had acquired direct experience on the natural life of orchids through collecting trips in the Philippines, Indonesia, Malaysia, Myanmar and India. In the greenhouses of Kagas Oyamazaki Villa, where some ten thousand orchids were grown, he made more than 1,100 crosses and germinated hundreds of hybrids, some of which were portrayed for the Rankafu collection. He retired from his position shortly before Kagas death in 1954. Finally, Zuigetsu Ikeda (1877) was hired in the early 1930s, and for the next twelve years he was the main artist at the Oyamazaki Villa, where he sketched and portrayed in watercolor thousands of plants. Of these, 83 found the way to be immortalized into the Rankafu woodblock prints. Another series of 60 water colors, intended for a second volume of the work, were never printed. Ikeda painted his last orchid from Kagas collection in 1942. botanical art printing available at the time, no
LANKESTERIANA 18(3). 2018. Universidad de Costa Rica, 2018. 244 LANKESTERIANA matter how expensive and costly (Kaga 1946), Shotaro Kaga asked help from the authorities on his expectations. Then, Kaga directed his attention to an old Japanese printing technique, that of wood engraving. This technique had began in Japan in the mid XVIII century and reached its highest standards during the XIX century. I guess that, until Kirby and his colleagues decided to publish their meticulous research on Rankafu just a handful of westerners had any knowledge of traditional Japanese wood engraving. Their work was instrumental not only to disclose the Rankafu to a larger audience, but also to the organization of an exhibition of the same name, held since last October at the Shirley Sherwood Gallery of Botanical Art, Kew Gardens, which will run until March 2019. Woodblock prints represent a spectacular art form, and a technical challenge but, as the used inks are water-based, it is particularly adapted to reproduce watercolour paintings. Highly specialized woodblock carvers transform the painting into prints, carving away the areas that are not to be printed on individual blocks of cherry tree ( Prunus serrulata ) for any of the colors of the painting, and leaving raised areas that may be as small as a fraction of a millimeter. one block to another. In the process, the original watercolor is usually lost, and no original Rankafu painting that corresponds to woodblock prints remains. The book is very instructive in describing the technique and the materials of woodblock printing in great detail. years of the war, 83 sets of Rankafu were printed at two different workshops and by at least six famous printers. Apart from the printings prepared from Ikedas watercolors, Kaga wanted to have printed in the Rankafu also a few black and white photographs taken by Toyo Okamoto, and nine conventional color print copies of colour oil paintings done by one of conventional copies (not woodblocks) of Ikedas painting are included into the prints collection. All these images are duly reproduced in the book together with the core section of woodblock printings. The superbly printed book showcases in full color the set owned by the senior author. Particularly well featured are species and hybrids of the Cattleya alliance, Cymbidium Dendrobium and slipper orchids, plus a number of orchid species from different groups, which were among the preferred orchids by Shotaro Kaga. The quality of the prints, and the delicacy of the compositions prepared by Ikeda, are simply stunning. In 1954, Shotaro Kaga died, and by 1958 the greenhouses were in disrepair. In 1967 Kaga heirs sold the Oyamazaki Villa, and by the 1970s the greenhouses had been demolished. It was the end of an era. The villa was fortunately brought back to its splendor during the 1990s, when the Asahi Beer Corporation acquired it and expanded it into the Oyamazaki Museum of Art, an important regional museum. As to the woodblocks, a series of originals for twelve woodblock printings were discovered in 2003 in Kyoto, in the warehouse of the Muira Printing Company. A set was reprinted with traditional woodblock printing methods, and was sold in 2005. Fortunately, the book by Kirby, Doi and Otsuka has now made available the complete set of these spectacular prints, which for their level of accuracy and artistic expression are justly considered masterworks of botanical art. I just want to echo the words by Phil Cribb, who introduced the book, warmly recommending this extraordinary work on a single collection of orchid prints, not only as a great introduction to a less known and highly decorative form of art, but also to the history of early modern Japanese orchid culture and some of its greatest proganists. It is an informative, varied, and really entertaining lecture. Franco Pupulin Lankester Botanical Garden University of Costa Rica
BOOKS 245 LANKESTERIANA 18(3). 2018. Universidad de Costa Rica, 2018. The Genus Phragmipedium A treatise on the conduplicate-leafed slipper orchids of Latin America by Guido J. Braem, Eliseo Tesn and Sandra L. hlund. Atlanta Belgium, privately printed by the author, 2018. jacket. $110.00. If you are interested in slipper orchids, The Genus Phragmipedium is a must have. The richly illustrated and colorfully executed book by Braem and collaborators is an essential guide. The book starts off with a short chapter on general followed by a very practical and detailed chapter on the cultivation of Phragmipedium species written by Eric Sauer. The main body of the book is composed of the treatment of individual taxa. Each is accompanied by a wealth of useful information from someone experience is transmitted throughout the book. Every accepted species includes a synonym list, type information, etymology, a discussion on history and a morphological description. Each of them is appropriately adorned with watercolors, photographs and plates. The rich illustrative material presented in species and also of varieties, subspecies and forms. by the many plants that are photographed in situ species as well, allowing easy comparison among closely related taxa. A few orchid people are also featured, including Henry Oakley and Cassio van den Berg. The book is full of short stories and side notes which make it very entertaining. An example is the story about the discovery of Phragmipedium lindenii Three slightly different versions are provided, starting with that of Linden himself. The discoverer of this notable species is famously quoted to have encountered the orchid when escaping from a bear. His account reads It was a bear that made me discover it, and this circumstance, coupled with my astonishment such a strange form, will always prevent me from forgetting such an encounter. I will not further spoil the story and encourage the reader to procure their copy of the book. Historical information is provided for several species. Especially interesting are the extensive commentaries surrounding the controversial discoveries and introduction into cultivation of the
LANKESTERIANA 18(3). 2018. Universidad de Costa Rica, 2018. 246 LANKESTERIANA Phragmipedium bessae and Phragmipedium kovachii The taxonomic treatment of each species is meticulously carried out. The reader is given all the elements that the authors use for each particular decision. They are extremely precise in arguing each detail in favor or against the recognition of taxa. Ample explanation of which morphological features are useful in species recognition is given throughout, this is extremely helpful to understand some of the lesser known names in the group. This objectivity is unfortunately lost when the taxa that have been described by the authors are involved. One example is the use of P. popowii Braem, Ohlund & Qun over P. humboldtii (Warsz.) J.T.Atwood & Dressler. The discussion as to the correct name of this species, articles in recent years, takes up several pages in this book. I am no expert on slipper orchids, nor on Germanic languages, but the code is clear. Article 46.2 explicitly states that a name can be ascribed to someone other than the author of an article it appears author and provides a, albeit brief, description, the taxon is for all effects validly published regardless of Reichenbachs own opinion. Another is perhaps the interpretation of good species within the Phragmipedium schlimii complex. Phragmipedium anguloi and both described by the senior author are accepted, whereas P. manzurii and P. ramiroi which are not, are regarded as synonyms. The arguments used to recognize these taxa are similar in each case, and not particularly strong. Nevertheless, taxonomic interpretation is always up for debate and the book looses no merit for what is an understandable defense of the authors own work. At the end it is far more important to document orchid diversity well and that is the biggest success serious drawback of The Genus Phragmipedium are the recurrent personal attacks on fellow botanists that appear on several instances throughout the otherwise highly entertaining read. Rather than give the book, or any argument therein, additional strength, the unnecessary critiques become tiring. The book would be much better without them. Besides these minor details, Braem, Tesn and hlund present a wonderful treatment of the genus Phragmipedium The book should be in the hands of every orchid enthusiast, especially those interested in slipper orchids. It should not be missed by anyone looking to know more about the historical details behind the controversial discovery and description of orchids with potential commercial value. The beauty, diversity and intrigue of Phragmipedium is uniquely represented in this outstanding work. Adam P. Karremans Lankester Botanical Garden University of Costa Rica
