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 ...
Genus-level taxonomical changes in the Lepanthes affinity (Orchidaceae: Pleurothallidinae)
(2018)
We propose a new classification of the Lepanthes affinity based on previous studies and our ongoing phylogenetic re-evaluation of the Pleurothallidinae. Fourteen genera are recognized as belonging to the affinity. They are ...
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, ...
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 ...
Lycaste Lindl.
(2020)
The British botanist John Lindley established Lycaste in Edwards’s Botanical Register in 1843. Based on morphological characters, he separated this group of orchids from the genus Maxillaria Ruiz & Pav. The generic name ...
Illustrations and studies in Neotropical Orchidaceae. 6. The Lepanthes guatemalensis group (Pleurothallidinae) in Costa Rica
(2014)
We revise and characterize the group of species close to Lepanthes
guatemalensis. The group comprises eight species in Costa Rica. Three
new species are described and illustrated. Lepanthes durikäensis is distinguished ...
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 ...
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), ...
Prosthechea tinukiana sp. nov. (Orchidaceae: Laeliinae): an update of the Prosthechea prismatocarpa complex
(2015)
We describe and illustrate a new species of Prosthechea from Costa Rica. The species is similar to Prosthechea ionocentra, but it is easily distinguishable by its inflorescence originating from the penultimate mature ...
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 ...
