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, ...

Orchid conservation in a private preserve at Palmares, Costa Rica
Madre Verde Private Preserve, located in Palmares (Alajuela, Costa Rica) protects a forest relict surrounded by pastures, bushes and abandoned agriculture grounds. An inventory was conducted in this preserve to determine ...
Preliminary molecular phylogenetics of Sobralia and relatives (Orchidaceae: Sobralieae)
With over 200 species, the orchid tribe Sobralieae is a major constituent of the Neotropical flora. As currently circumscribed, the tribe includes four genera: Elleanthus, Epilyna, Sertifera, and Sobralia. Most species ...
Myoxanthus vittatus (Orchidaceae), a new species from Costa Rica
The taxonomic position of Myoxanthus Poepp. & Endl. (Orchidaceae: Pleurothallidinae) is discussed and Silenia Luer is maintained as a subgenus of Myoxanthus. A new species of Myoxanthus is described and illustrated. ...
Un híbrido espontáneo entre Aristolochia gorgona y A. grandiflora (Aristolochiaceae)
A spontaneous hybrid between Aristolochia gorgona and A. grandiflora appeared at Lankester Botanical Garden, Costa Rica, where plants of both species were cultivated in close proximity. This indicates that geographic ...
A taxonomic synopsis and morphological characterization of Myoxanthus (Orchidaceae: Pleurothallidinae)
The taxonomic history, general description and distribution are provided for Myoxanthus. Morphological characterization of the vegetative and reproductive organs is illustrated with photographs. A list of the 52 accepted ...
Resolving relationships in an exceedingly young Neotropical orchid lineage using Genotyping-by-sequencing data
Poor morphological and molecular differentiation in recently diversified lineages is a widespread phenomenon in plants. Phylogenetic relationships within such species complexes are often difficult to resolve because of the ...
Molecular phylogenetics of Maxillaria and related genera (Orchidaceae: Cymbidieae) based on combined molecular data sets
The orchid genus Maxillaria is one of the largest and most common of neotropical orchid genera, but its current generic boundaries and relationships have long been regarded as artificial. Phylogenetic relationships within ...
Pseudocopulatory pollination in Lepanthes (Orchidaceae: Pleurothallidinae) by fungus gnats
Background and Aims: Lepanthes is one of the largest angiosperm genera (>800 species). Their non-rewarding, tiny and colourful flowers are structurally complex. Their pollination mechanism has hitherto remained unknown, ...
