How many species of Pleurothallidinae are there?
(2019)
Subtribe Pleurothallidinae is possibly the most species-rich of all orchid groups. Nevertheless, they are a young group of plants in terms of scientific learning. The last three decades have been the most active with respect ...
Orchidaceae tonduzianae: Typification of Costa Rican Orchidaceae Described from Collections of Adolphe Tonduz
(2016-12-31)
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 ...
Further disentangling of a taxonomic puzzle: Maxillaria Ramosa, Ornithidium Pendulum, and a new species, O. Elianae (Orchidaceae)
(Harvard Papers in Botany, 2008)
McIllmurray and Oakeley (2004) demonstrated that the name Maxillaria ramosa has been misapplied
to Ornithidium pendulum since 1967, and possibly corresponds to M. cassapensis. We refer Ornithidium
ochraceum, O. loefgrenii, ...
A new Lepanthes (Orchidaceae: Pleurothallidinae) from Península de Osa, Puntarenas, Costa Rica
(2020-12-31)
Lepanthes is one of the most species-rich genera of orchids in the Neotropics, with most of the species found in medium to high elevation forests and few species in lowlands. We describe and illustrate Lepanthes osaensis, ...
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), ...
The orchid flora of Cocos Island National Park, Puntarenas, Costa Rica

The orchid flora of Cocos Island National Park, Costa Rica is described based on field collections and herbarium sampling. Cocos Island is an oceanic island situated 550 km south-west of Puntarenas (the main Costa Rican ...
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 ...
