Two new species of Epidendrum are described and illustrated from Costa Rica. Epidendrum fulfordianum is compared with E. chlorocorymbos, from which it can be distinguished by the much larger flowers, the wider petals and ...

This paper focuses on the systematics of the Specklinia endotrachys species complex in Costa Rica. Traditionally considered a variable species, S. endotrachys is here treated as one of at least four, albeit closely related, ...

Stelis, one of the largest genera within Pleuro- thallidinae, was recently recircumscribed to include a few hundred more species, most of which had previously been assigned to Pleurothallis. Here, a new phylogenetic anal- ...

A new species of Trichocentrum (Orchidaceae: Oncidiinae) from southeastern Ecuador, T. loyolicum, is described and illustrated. Trichocentrum loyolicum is compared with T. pulchrum, from which it mainly differs by the ...

The phylogenetic relationships within the Acianthera affinity are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data. Emphasis is made on species from the Antilles, Central America and the ...

Specklinia dunstervillei is described as a new species in recognition of the distinctness of a Venezuelan species related to and confused with Specklinia endotrachys. It was illustrated for the first time by G. C. K. ...

Crossoglossa sotoana, a new species from Costa Rica, is described and illustrated. It is compared with Ecuadorian C. barfodii, from which it differs by the strongly undulate margins of the leaves, the resupinate flowers, ...

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. ...

Background and Aims The first documented observation of pollination in Pleurothallidinae was that of Endre ́s, who noticed that the ‘viscid sepals’ of Specklinia endotrachys were visited by a ‘small fly’. Chase would later ...

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 ...
