Pleurothyrium amissum P. Juárez & J. F. Morales (Lauraceae), a new species endemic to the highland oak forests of the Costa Rican Talamanca range, is described and illustrated. Pleurothyrium amissum and P. pauciflorum van der Werff & Hammel have similar floral morphology but differ by their height, leaf size, inflorescence size, number of flowers per inflorescence, flower color, and habitat. Photographs, a distribution map, and a key to the species of Pleurothyrium Nees in Costa Rica are presented.

A New Species

Telipogon mayoi, from the western Colombian Andes, is proposed as a new species. The species was found in “La Elvira” National Protective Forest in the Yumbo Municipality, one of the oldest protected areas in Colombia, close to the Farallones de Cali National Park, both localities in the Dapa Mountains. Specimens of Telipogon mayoi were previously misidentified as Telipogon lankesteri Ames and T. williamsii P.Ortiz, but detailed analysis of the floral morphology revealed that it is different. Telipogon mayoi is most similar to T. lankesteri but it is characterized by the crenulated margins of the leaves (vs. entire margins), the ovate oblong lip (vs. oblong lanceolate) and furcate setae on the column (vs. simple setae). We provide a description, illustrations, a plate, in situ photographs, a distribution map, and ecological notes. Key Words: Andes, cloud forest, Colombia, miniature Telipogon, Oncidiinae

Primula luteoflora, a new species of Primulaceae from Sichuan, China, is described and illustrated here. It is morphologically assigned to Primula sect. Petiolares subsect. Davidii, characterized by the leaves firmly papery or leathery, with adaxially impressed veins and reticulate veins distinctly raised abaxially. However, the new species is distinguished by its leaf size, number of lateral veins, glabrous scape, number of flowers and yellow flowers.

A New Species

We propose the new species Maxillaria bicentenaria from the montane forest of central Peru and provide an amendment of the description of Maxillaria pyhalae. Maxillaria bicentenaria is similar to M. pyhalae but differs by the elliptic to sub-elliptic labellum, the labellum distal half irregularly plicate, the flattened and transversally sub-trapezoidal labellar callus, the campanulate to sub-campanulate protuberance at the labellum apex centre, and the conspicuous carina with a sharp edge towards the top of the anther. Illustrations, pictures, and a distribution map are provided for both Maxillaria species. The differential features of both species are presented and previous misidentified records are discussed. Finally, a comment on the author name of Maxillaria fletcheriana is also provided.

A New Species

Eurystyles comprises about 23 species ranging from Mexico to northern Argentina. Six species are recognized in Mexico and Central America and three in Costa Rica. A new species, named E. uxoris, is here described and illustrated based on Costa Rican material. The species is similar to Eurystyles auriculata and E. standleyi, however, it differs by the smaller plants up to 3 cm tall, smaller leaves of less than 1.6 cm long, flowers with brown dorsal sepal and brown lip apex, petals callose or thickened at apex, and a pandurate lip. Information about distribution, habitat, ecology, etymology and phenology of the newspecies is provided. An updated key to the Costa Rican species of Eurystyles is presented.

Different Altitudes

The Centella asiatica is an important herbal plant in Indonesia. The research was done to describe severalagronomic traits that related to yield of the plants grown at regions with different altitudes. The research wascarried out at three different regions of highland, midland, and lowerland, each at >500m, 250-500m, and < 250mabove sea level. The research location was Pagar Alam, Musi Rawas, and Ogan Ilir, respectively. Research indicatedthat the agronomic traits of the plants grown at highland, midland, and lowerland, regions were about the same forgeneral appearance of leaf shape and flower color. The leaf size, number and length of stolone, number of rossets,length of rhizomes, and number of flower were varied depending on the region. The plants grown at highland andmidland region tend to have larger leaf size, shorter petiole and stolone, more number of rossets and stolone,longer rhizomes, and more number of flowers per plant, compared to the plants of lowerland region. This could beindication that Centella asiatica plants grown on midland, and highland were more productive than plants oflowerland region.

A New Species

Spathacanthus is a Mesoamerican genus that occurs in tropical and temperate regions from southern Mexico to Costa Rica; its taxonomy has not been updated for two decades. In view of the fact that a new species has been discovered and that the interspecific affinities in this genus have not been addressed to date, the present study aims to revise the genus Spathacanthus. Specimens of plants of this genus collected from across the distribution range and deposited in herbaria and digital databases were reviewed. In parallel, a cladistic analysis was carried out, based on morphological characters in order to examine relationships between species. Four species of Spathacanthus were recognised: one endemic to Costa Rica, another micro-endemic to Veracruz in Mexico, one more restricted to the forests of Mexico and Guatemala and the last one more widely distributed. Reflecting the previously limited knowledge of the group, many of the specimens that we studied had been misidentified. A key to differentiate these species is provided, supplemented with photographs, drawings and other illustrations, morphological descriptions, synonymy and ecological data. Results, presented here, extend the distribution range of some taxa and a distribution map is presented. The cladistic analysis recovered the genus as monophyletic, showing that S. hoffmannii and S. hahnianus are sister taxa and S. magdalenae was found to be more closely related to S. parviflorus. These plants are vulnerable to degradation and habitat loss.

A New Species

A new species of Muscarella from Costa Rica, is described and illustrated. Muscarella tapantiensis most resembles M. coeloglossa but differs in the longer pedicels (3-5 vs. 1-2 mm), the shorter (2.5-2.8 vs. 3.75 mm), connate (vs. free) lateral sepals, and the lip with triangular (vs. broadly rounded) lower lateral lobes. Muscarella xanthella also resembles M. tapantiensis; however, it differs in the successively flowered raceme with alternate pedicels, the deeply fimbriate petals and the thick, rounded lip with densely verrucose lateral lobes. We provide illustrations, etymology, notes on ecology, pictures of the plants and habitat, and a distribution map of the new species. We discuss the inclusion of this species in the genus Muscarella.

A New Species

Zamia acuminata has remained an obscure, poorly understood species for over a century due to possibly misinterpreted or erroneous locality data on the unicate sterile type specimen, a very brief protologue description, the misidentification of the plants from El Valle de Antón in Panama as Z. acuminata, and the erroneous determinations of plants of Z. acuminata from Costa Rica as Z. fairchildiana. Recently collected material from San José Province in Costa Rica is here determined to be identical to the single sterile leaf material of the holotype of Zamia acuminata. We consider Z. acuminata to be a Costa Rican endemic species restricted to the western Talamanca mountain range in San José Province, and that the Zamia from El Valle de Antón in Panama, which has previously been referred to as Zamia acuminata, to be a new species, here described as Zamia nana.
