Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot
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, ...
Phylogenetic reassessment of Specklinia and its allied genera in the pleurothallidinae (Orchidaceae)
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. ...
Two novelties in genus Platystele (Orchidaceae: Pleurothallidinae) from Costa Rica
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 ...
Phylogenetic comparative methods improve the selection of characters for generic delimitations in a hyperdiverse Neotropical orchid clade
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 glandulous Specklinia: morphological convergence versus phylogenetic divergence
The present paper focuses on the systematics of the Specklinia glandulosa species complex. Traditionally, S. glandulosa has been considered a widely distributed and variable species, ranging from Mexico to the guiana Shield. ...
