Abstract and Figures

AbStrAct. Three new species of Lepanthes from south-east Costa Rica are described and illustrated. Lepanthes erubescens resembles L. limbellata, from which it can be distinguished by the pendent plants, with inflorescences that borne above the leaf, the upper petal lobe ovate, acute, 1,3 mm wide, larger than the lower lobe, and the ovate lip. Lepanthes sandiorum resembles L. dolabriformis, however it can be distinguished by the smaller plants, the smaller flowers, the narrower petals, which are filiform, with the upper lobe oblong, rounded, entire and glabrous. Lepanthes sanjuanensis is similar to L. elegans, but it is distinguished by the green-purple, un-reticulated leaves, the petals with the upper lobe oblong, rounded, with the margins red, the lower lobe oblong, rounded, divergent at apex, and the pinkish or orange-red lip. Additional comments on the species are provided.

AbStrAct. Three new species of Lepanthes from south-east Costa Rica are described and illustrated.
Lepanthes erubescens resembles L. limbellata, from which it can be distinguished by the pendent plants, with
inorescences that borne above the leaf, the upper petal lobe ovate, acute, 1,3 mm wide, larger than the lower
lobe, and the ovate lip. Lepanthes sandiorum resembles L. dolabriformis, however it can be distinguished by
the smaller plants, the smaller owers, the narrower petals, which are liform, with the upper lobe oblong,
rounded, entire and glabrous. Lepanthes sanjuanensis is similar to L. elegans, but it is distinguished by the
green-purple, un-reticulated leaves, the petals with the upper lobe oblong, rounded, with the margins red, the
lower lobe oblong, rounded, divergent at apex, and the pinkish or orange-red lip. Additional comments on
the species are provided.
Key worDS: Orchidaceae, Pleurothallidinae, Lepanthes erubescens, Lepanthes sandiorum, Lepanthes
sanjuanensis, new species, taxonomy
Lepanthes comprises about 120 species in Costa
Rica. The taxonomic history of the genus in the counry
began with the arrival of the explorers A. Oersted
and H. Wendland in the second half of the nineteenth
century. They collected Lepanthes between 1855 and
1857, mostly at El Desengaño and Cartago, along the
mountains of the Valle Central. H.G Reichenbach f.
described 8 new species from among their collections
(Reichenbach 1866). From that same year and up
to 1874, botanist Auguste R. Endrés thoroughly
explored Costa Rica, documenting almost half of the
known species of Lepanthes now reported from the
country. Endrés gathered more than 250 specimens,
corresponding to 63 species and prepared 201
illustrations (Pupulin et al. 2011). Unfortunately his
work was never published and at least 55 species of
Lepanthes remained undescribed until Luer (1995)
studied his material kept at W.
Between 1912 and 1923, R. Schlechter published
18 species based on material collected in Costa
Rica. The material was gathered mostly by G.
Acosta, the brothers A. and C. Brade, A. Brenes, H.
Pittier, A. Tonduz and C. Wercklé (Schlechter 1923).
Contemporarily, O. Ames, who received material
from C. Lankester, also added about 22 species to the
genus (Ames 1923). After the pasing of O. Ames and
R. Schlechter, the description of new orchid species
in Costa Rica declined considerably. No Lepanthes
species were described during the next 53 years.
Luer (1983) began to describe new Lepanthes
species based on his own eld work activities since
1981, but mainly from studying Endrés’ material that
remained forgotten for over a century. Indeed, even
with the contributions of Reichenbach, Schlechter and
Ames, the diversity of Lepanthes was far from being
understood. Luer (1996) added 70 species (almost
doubling the number of species known to date) to the
ora of Costa Rica. About 21 of them were based on
the collections by Endrés (Luer 1995).
After Luer (1995, 1996), and with the turn of
the century, research at Lankester Botanical Garden
(JBL) has revealed some 22 new species of Lepanthes.
Those studies mostly covered areas not visited by the
traditional collectors mentioned previously (Pupulin
et al. 2010). The area that comprises the Southern
Pacic watershed of the Talamanca mountain range,
from the foothills of Cerro de la Muerte and Chirripó,
neighboring the Valle de El General, Fila Costeña
and up to the border with Panama, in the Costa Rican
south-east, is very rich in Lepanthes species.
Here we propose three new species from this
region of Costa Rica:

DiStribution: Endemic to Costa Rica, however, most
probably found also in Panama, as the large populations
were found growing very close to the border. It is
known only from the south-east Costa Rica, on the
southernmost portion of the Pacic watershed of the
Talamanca mountain range.
hAbitAt AnD ecoloGy: plants were found growing
epiphytically in disturbed lower montane rain forest, at
around 1800 m elevation.
ePonymy: dedicated to Miguel Sandí and his family,
pioneers in the region of Las Tablas and owners of the
farm where this species was found.
Lepanthes sandiorum resembles L. dolabriformis
Luer, however it can be distinguished mainly by the
smaller plants, less than 5.5 cm tall (vs. up to 7.5 cm),
the smaller owers with sepals 2.6 × 1.4 mm (vs. 4.0
× 2.5 mm), the narrower petals, which are liform,
2.3 mm (vs. 3.5–3.75 mm) with the upper lobe
oblong, rounded, entire, glabrous (vs. obtusely angled
with a hatchet-shaped appearance, minutely ciliate,
pubescent). Both species are related to L. blepharistes
Rchb.f. but they can be easily distinguished by the
petals with the lower lobe smaller than the upper lobe
(vs. equal in length).

hAbitAt AnD ecoloGy: a population was found
epiphytically in premontane moist forest in secondary
vegetation, at around 1000-1200 m of elevation.
etymoloGy: named after the type locality of Alto de
San Juan, along the road from San Isidro de El General
to Dominical.
Lepanthes sanjuanensis is similar to L. elegans
Luer. Both are characterized by the relatively large
to the plant habit, produced below the leaf, and the lip is
minute with conspicuous long-ciliate apexes. However,
L. sanjuanensis is mainly distinguished by the green-
purple, not reticulated leaves (vs. reticulated), the
petals with the upper lobe oblong, rounded, with the
margins red (vs. obliquely ovate, with a red blotch at
the middle of the upper lobe), the lower lobe oblong,
rounded, divergent at apex (vs. obliquely triangular,
acute, converging) and the pinkish or orange-red lip
(vs. yellow).

El género neotropical Lepanthes es uno de los grupos más grandes dentro de Orchidaceae. Aquí se reporta por primera vez la presencia de Lepanthes fratercula en la flora de México. Además, se clarifica el estatus taxonómico de L. quetzalensis, considerándola como una especie diferente de L. scopula, en la cual había sido incluida como su sinónimo. Tanto L. fratercula como L. quetzalensis son descritas a partir de ejemplares mexicanos recolectados en el estado de Chiapas. Para cada taxón se proporciona información sobre su distribución, hábitat, fenologíay estatus de conservación en México; adicionalmente, ambas especies son comparadas con otros taxones morfológicamente similares de América Central. La riqueza de Lepanthes para la flora mexicana se incrementa a 65 especies, siendo 35 de ellas nativas de Chiapas.

Aim The aim of this analysis was to identify strategies that will maximize efficiency and effectiveness in conservation planning. As many orchids are threatened with extinction for various reasons, our primary objective was to combine hotspots analyses with stochastic extinction modelling to highlight possible conservation priorities for Lepanthes spp. (Orchidaceae) based on patterns of richness, rarity and threat. Our subsequent objective was to identify potential conservation surrogates and variables that are the best predictors of extinction probabilities. The ultimate goal was to determine which factors should be emphasized in conservation planning to prevent species extinctions. Location Latin America; the Caribbean. Methods We used herbarium records and Arc GIS to map the distribution of Lepanthes spp. and to identify hotspots of richness and rarity. We forecasted extinction patterns with Koopowitz's stochastic extinction model and calculated extinction probabilities in each country. We used a randomForest regression model in R to assess the importance of richness, rarity and threat for explaining extinction probabilities. Results Hotspots of Lepanthes richness and rarity occurred in north‐western South America and southern Central America and largely overlapped with each other. The highest extinction probabilities occurred in northern Central America, Haiti and Ecuador, and generally, hotspots of richness and rarity did not correspond with patterns of threat. Habitat loss was the most important variable for explaining extinction probabilities, followed by measures of rarity. Main conclusions Conservation efforts will be most efficient in richness and rarity hotspots, and because they overlap, rarity hotspots could act as surrogates for protecting overall Lepanthes diversity. Hotspots rarely occurred in the most threatened areas, and therefore, conservation efforts are more urgent in non‐hotspot areas. Conservation efforts will be most effective if they combine ex situ strategies in locations with high habitat conversion rates with reservation strategies in rarity and richness hotspots, particularly where they overlap.

We provide a general introduction to the prodromi to Flora Costaricensis, and an introduction to the precursors of subtribe Pleurothallidinae. We present a systematic revision of the genus Echinosepala for the flora of Costa Rica and a detailed discussion of molecular evidence with regard to most Costa Rican taxa, aimed at phylogenetically framing Echinosepala within the subtribe Pleurothallidinae, recognizing internal relationships among the species in the genus, and proposing evolutionary hypotheses. We recognize 10 species of Echinosepala in Costa Rica. Each species is described and illustrated with one or more botanical drawings and photographs, all based on Costa Rican material. Etymology, distribution, ecology, distinguishing features, and affinities with other taxa in the genus are discussed, taxonomic notes are provided, and a list of selected material examined for this study is included for each taxon. Two new species of Echinosepala, E. glenioides and E. isthmica, are described and illustrated, and their relationships are discussed. New combinations are proposed in Echinosepala for Pleurothallis alexandrae and P. pastacensis, and the former species is neotypified.
