Phylogenetics of Stelis and closely related genera (Orchidaceae: Pleurothallidinae)
Stelis, one of the largest genera within Pleurothallidinae, was recently recircumscribed to include a few hundred more species, most of which had previously been assigned to Pleurothallis. Here, aExpand

Genera Pleurothallidinarum: an updated phylogenetic overview of Pleurothallidinae
Subtribe Pleurothallidinae with just over 5000 species is possibly the most species-rich of all orchids. It has been growing steadily for more than two centuries, but the last three decades have beenExpand

LANKESTERIANA, A NEW GENUS IN THE PLEUROTHALLIDINAE(ORCHIDACEAE)
We estimated phylogenetic relationships within Anathallis and related genera using Bayesian analyses of nrITS sequence data. The genus is biphyletic in the molecular trees. A novel generic concept,Expand

A reconsideration of the empusellous species of Specklinia (Orchidaceae: Pleurothallidinae) in Costa Rica
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,Expand

Specklinia dunstervillei, a New Species Long Confused with Specklinia endotrachys (Orchidaceae: Pleurothallidinae)
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 firstExpand

Phylogenetic analysis of Andinia (Pleurothallidinae; Orchidaceae) and a systematic re-circumscription of the genus
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 generaExpand
