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), ...
Pollinaria: up close and personal
(2011-06)
Pollinaria are complex structure, in many cases composed of different elements that originate from different parts of the reproductive organs of the plant.
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 ...
Near-neighbor tropical epiphytic orchids keep distinct mycorrhizal communities across their distribution in Costa Rica
(2022)
Environmental and biotic axes act in combination to define the ecological niches of plant species. Two species with shared physical space are expected to compete for access to water and nutrients. In hyper-diverse areas ...

Tubella - those other Trichosalpinx
(2013-10)
Die Gattung Trichosalpinx gehört zur Subtribus Pleurothallidinae und wurde vor 30 Jahren von C.A. LUER (1983) neu beschrieben. Später wurde sie in vier Untergattungen, Trichosalpinx, Tubella, Pseudolepanthes und Xenia (LUER ...
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 ...
Lepanthes aures‐ursinae and L. vertebrata spp. nov. (Orchidaceae: Pleurothallidinae) from Panama
(2017)
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 ...
