The phylogenetic relationships within Specklinia (Pleurothallidinae; Orchidaceae) and related genera are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data of a wide sampling of species. ...

Taxonomic delimitations are challenging because of the convergent and variable nature of phenotypic traits. This is evident in species-rich lineages, where the ancestral and derived states and their gains and losses are ...

The ten Costa Rican species of Myoxanthus are discussed, described and illustrated based mainly on native living material. a key for the species, notes on history, ecology, diagnostic features, taxonomy and distribution ...

Most of the species studied in this paper have previously been placed in either Pleurothallis or Lepanthes. However, at one time or another, members of the group have also been placed in the genera Andinia, Brachycladium, ...

Pleurothallis cerea, a species described based on a specimen collected by Lankester in Costa Rica, and commonly placed under the synonymy of Myoxanthus octomeriae or M. congestus, is here recognized as distinct. The species ...

A new species of Lepanthes from the Western Cordillera of the Colombian Andes, characterized by similar triangular sepals with a large and protruding column, is described and illustrated. The new species is similar to ...

Two new species of Platystele allied to P. oxyglossa complex are described from Costa Rica. Platystele carl-lueriana can be distinguished from P. catiensis and P. oxyglossa by the compact inflorescence that barely exceeds ...

The era or Carlyle Luer, which currently comprehends the forty-two years since the publication of the first Icones Pleurothallidinarum in 1975, has witnessed a true revolution in the knowledge and understanding of the ...

The Andean mountains of South America are the most species‐rich biodiversity hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land surface. Orchids are a key element of the Andean flora, ...
