The glandulous Specklinia: morphological convergence versus phylogenetic divergence
(2015-07)
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. ...
Pollination of Trichosalpinx (Orchidaceae: Pleurothallidinae) by biting midges (Diptera: Ceratopogonidae)
(2018)
Pleurothallidinae (Epidendreae) are a megadiverse Neotropical orchid subtribe comprising > 5100 species, most of which are probably pollinated by Diptera. The role of pollinators as drivers of species diversity is largely ...
Typification of Costa Rican Orchidaceae described by Rudolf Schlechter. Species variorum collectorum
(2022-04)
The typification of 53 orchid species described by Rudolf Schlechter based on specimens gathered in Costa Rica by Paul (Pablo) Biolley, Juan José Cooper Sandoval, Auguste R. Endrés, Carl Hoffmann, Emel Jiménez Segura, Otón ...
Floral anatomy and evolution of pollination syndromes in Lepanthes and close relatives
(2019-07)
Pleurothallidinae is the largest Neotropical orchid subtribe encompassing >5100 species that are mainly dipteran-pollinated. Various pollination syndromes, targeting hump-backed flies (Phoridae), fungal gnats (Sciaridae), ...
Phylogenetic comparative methods improve the selection of characters for generic delimitations in a hyperdiverse Neotropical orchid clade
(2019)
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 ...

(2022-12)
The genus Sarcoglottis was named in 1827 by Czech botanist Carl Borivoj Presl, a professor at the University of Prague. The name comes from the Greek sarkos, meaning flesh, and glotta, tongue, in reference to the texture ...

Barra Honda National Park (BHNP) lies in the Tempisque River Basin of the Península de Nicoya, Guanacaste, Costa Rica.
The Park is well known for its limestone caverns, which date from the Upper Paleocene–Lower Eocene and ...
Phylogenetic reassessment of Acianthera (Pleurothallidinae: Orchidaceae)
(2016-12-31)
The phylogenetic relationships within the Acianthera affinity are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data. Emphasis is made on species from the Antilles, Central America and the ...
A new Muscarella from Tapanti National Park, Costa Rica
(2021)
A new species of Muscarella from Costa Rica, is described and illustrated. Muscarella tapantiensis most resembles M. coeloglossa but differs in the longer pedicels (3-5 vs. 1-2 mm), the shorter (2.5-2.8 vs. 3.75 mm), connate ...
