(2019)
Los Cerros de La Carpintera son una formación montañosa en el Valle Central de Costa Rica que alberga remanentes de bosque nuboso en sus partes altas y están rodeados por áreas urbanas y agrícolas. Con el interés de promover ...
Costa Rica, land of endless orchids
(2013-07)
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. ...
Capillitial extrusion from fruits of Maxillaria nardoides (Orchidaceae: Maxillariinae)
(2006-09)
The fruits of Maxillaria nardoides are fusiform, 1–1.2 × 0.3 cm. Upon dehiscence, six valves separate completely at the apex, and a long cylindric mass (up to 6.5 cm long × 3 mm in diameter) of white hygroscopic trichomes ...
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 ...

(2016-11-20)
A clear, step by step description of the treatment of orchid flowers, subtribe Pleurothallidinae, with Critical Point Drying for SEM is presented. It shows that a simple, short fixation and dehydration method prior to ...
Pollination of Specklinia by nectar-feeding Drosophila: the first reported case of a deceptive syndrome employing aggregation pheromones in Orchidaceae
(2015)
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 ...
