Orchidaceae tonduzianae: Typification of Costa Rican Orchidaceae Described from Collections of Adolphe Tonduz
The Swiss botanist Adolphe Tonduz worked in Costa Rica from 1889 to 1920. For 20 years he carried out important activities as a plant collector and the curator of the largest Costa Rican herbarium beginning at the Instituto ...
Illustrations and Studies in Neotropical Orchids. 2. A note on Pleurothallis luctuosa (Orchidaceae: Pleurothallidinae), with a new species
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. ...
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 ...
Floral anatomy and evolution of pollination syndromes in Lepanthes and close relatives
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), ...
Pollination of Trichosalpinx (Orchidaceae: Pleurothallidinae) by biting midges (Diptera: Ceratopogonidae)
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 ...

Lepanthes aures‐ursinae and L. vertebrata spp. nov. (Orchidaceae: Pleurothallidinae) from Panama
Panama is still far from completing its orchid flora inventories, where large genera such as Lepanthes (Pleurothallidinae) reveal novelties regularly. Here, we describe and illustrate two new species of Lepanthes. Lepanthes ...
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 ...
