Resolving relationships in an exceedingly young Neotropical orchid lineage using Genotyping-by-sequencing data
(2020-03-01)
Poor morphological and molecular differentiation in recently diversified lineages is a widespread phenomenon in plants. Phylogenetic relationships within such species complexes are often difficult to resolve because of the ...
A new Trichosalpinx (Orchidaceae: Pleurothallidinae) from the northern Pacific lowlands of Costa Rica

A new species of Trichosalpinx from the Pacific lowlands of Costa Rica is described and illustrated. Trichosalpinx reflexa, which is morphologically most similar to T. memor and T. ciliaris, is distinguished mainly by the ...
Hundreds of nuclear and plastid loci yield novel insights into orchid relationships
(2021)
PREMISE: The inference of evolutionary relationships in the species- rich family Orchidaceae has hitherto relied heavily on plastid DNA sequences and limited taxon sampling. Previous studies have provided a robust plastid ...
Florae costaricensis subtribui Pleurothallidinis (Orchidaceae) prodromus II. Systematics of the Pleurothallis cardiothallis and P. phyllocardia Groups, and Other Related Groups of Pleurothallis with Large Vegetative Habit
