With almost 1,600 reported species (Karremans et al. 2012), Costa Rica has one of the richest orchid floras in tropical America, currently surpassed in total species number only by Brazil, Colombia, Ecuador and Peru (Govaerts ...
Illustrations and Studies in Neotropical Orchids. 2. A note on Pleurothallis luctuosa (Orchidaceae: Pleurothallidinae), with a new species
(2010)
The identity of Pleurothallis luctuosa, its taxonomic history and geographic distribution are discussed, and the species is described and illustrated. A new species from Costa Rica, P. neglecta, is described and illustrated. ...
Evolution of Seed Dispersal Modes in the Orchidaceae: Has the Vanilla Mystery Been Solved?
(2023)
Orchid seeds are predominantly wind-dispersed, often developed within dry, dehiscent fruits that typically release millions of dust-like seeds into the air. Animal-mediated seed dispersal is a lesser-known phenomenon in ...
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
(2011-12-23)
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
(2021)
We discuss a group of Pleurothallis species mostly characterized by plants relatively tall for the genus, with stems more than 20 cm long and fasciculate inflorescences produced above the leaf from a spathaceous, sometimes ...

(2017)
Masdevallia luerorum from the southern Pacific region of Costa Rica is described and illustrated. It resembles M. lata, but differs in the single flowered inflorescence, the shorter sepals, the broad and cylindrical sepaline ...
Lepanthes arenasiana (Orchidaceae: Pleurothallidinae), a new species from Costa Rica
(2010-01)
Lepanthes arenasiana from the Talamanca range in Costa Rica is described and illustrated. It is most similar to L. lancifolia but differs in having denticulate sepals, the petals with the upper lobe oblong, narrowing at ...
Brachionium kirbyi, a new species honoring the founder of the “Bosque de Paz” Orchid Project in Costa Rica
(2015)
A new species of Brachionidium from Costa Rica is described and illustrated. Brachionidium kirbyi is most similar to Brachionidium dressleri Luer. It can be recognized by the erect plants, up to 14 cm tall, often branching, ...
