Stelis dies-natalis y Stelis aenigma, pertenecientes a un grupo de especies en su mayoría Centroamericanas colocadas alternativamente en el género Dracontia, son descritas e ilustradas basadas en material vivo. Ambas se encontraron en robledales de altura en diferentes picos de la Cordillera de Talamanca en Costa Rica. La primera, S. dies-natalis,...

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.
The new genus Pridgeonia, and eight new orchid species in the genera Benzingia, Daiotyla, Dichaea, Ixyophora, and Pridgeonia, all belonging to the subtribe Zygopetalinae, are described. Complete descriptions, with notes on etymology, habitat, and ecology, and discussion of phylogenetic affinities, are provided for each new taxon, supplemented with line drawings, photographs, digital composite plates, and distribution maps. New combinations and synonyms are proposed in the genera Aetheorhyncha, Benzingia, Dichaea, and Ixyophora. Dichaea dressleri and Kefersteinia alata are recorded and illustrated for the first time for the flora of Costa Rica. Keys for the genus Benzingia and the Costa Rican species of Dichaea are proposed.
Lepanthes agatarum, a new species of Orchidaceae from the eastern Andes of Colombia, with cup-shaped flowers, is described and illustrated. The new species is similar to Lepanthes calocodon from Venezuela, but can be distinguished from it by its longer petals and a bilaminate lip with the blade apices elongate, long acuminate-slender to filiform. Resumen Lepanthes agatarum, una nueva especie de Orchidaceae de los Andes orientales de Colombia, caracterizada por tener flores en forma de copa, es descrita e ilustrada. Esta nueva especie es similar a Lepanthes calocodon, de Venezuela, pero se puede distinguir de esta última por sus petalos mas largos y el labelo bilaminado con los apices de las láminas alargados, finos y longitudinalmente acuminados a filiformes.
