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 ...
The Lankester Catalogue of Costa Rican Orchidaceae
(2023-12-30)
Abstract. This study presents an updated comprehensive catalogue of the Costa Rican orchid flora. We have documented 1684 species, four subspecies, 14 natural hybrids, and seven forms across 201 genera and two nothogenera, ...
Phylogenetic reassessment of Specklinia and its allied genera in the pleurothallidinae (Orchidaceae)
(2016)
The phylogenetic relationships within Specklinia (Pleurothallidinae; Orchidaceae) and related genera are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data of a wide sampling of species. ...
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 ...
Florae costaricensis subtribui pleurothallidinis prodromus—Systematics of Echinosepala (Orchidaceae)
(2020-12)
We provide a general introduction to the prodromi to Flora Costaricensis, and an introduction to the precursors of subtribe Pleurothallidinae. We present a systematic revision of the genus Echinosepala for the flora of ...
Una nueva especie de Cischweinfia (Orchidaceae: Oncidiinae) de Costa Rica, con hábito y flores muy pequeñas
(2020)
Se describe e ilustra, de Costa Rica, una nueva especie de Cischweinfia, C. gersonii. Se compara con C. pygmaea del Ecuador, de la cual se puede distinguir por la infl orescencia sucesiva con las fl ores abiertas una a la ...
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 ...
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. ...
