Documentation of floral secretory glands in Pleurothallidinae (Orchidaceae) using Scanning Electron Microscopy (SEM)
A clear, step by step description of the treatment of orchid flowers, subtribe Pleurothallidinae, with Critical Point Drying for SEM is presented. It shows that a simple, short fixation and dehydration method prior to ...
Phylogenetic reassessment of Specklinia and its allied genera in the pleurothallidinae (Orchidaceae)
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. ...
Pollination of Specklinia by nectar-feeding Drosophila: the first reported case of a deceptive syndrome employing aggregation pheromones in Orchidaceae
Background and Aims The first documented observation of pollination in Pleurothallidinae was that of Endre ́s, who noticed that the ‘viscid sepals’ of Specklinia endotrachys were visited by a ‘small fly’. Chase would later ...
Nomenclatural notes in the Pleurothallidinae (Orchidaceae): miscellaneous part II
Nomenclatural changes and notes are provided for genera in subtribe Pleurothallidinae (Epidendroideae: Orchidaceae) to comply with the International code of nomenclature for algae, fungi, and plants. The proposed changes ...
A new species of Pabstiella (Pleurothallidinae, Orchidaceae) from Ecuador
Pabstiella elegans is newly described based on cultivated material originally collected near Chaucha in Ecuador. It belongs to the group of small, creeping species of Pabstiella section Mentosae and differs from its closest ...
This volume consists of 100 botanical illustrations of the genus Epidendrum, comprising 20 species new to science, a new name, and 79 species of the genus, in some cases illustrated for the first time.
Trichocentrum Loyolicum, A New Species in the Genus Trichocentrum S. Str. (Orchidaceae: Oncidiinae)
A new species of Trichocentrum (Orchidaceae: Oncidiinae) from southeastern Ecuador, T. loyolicum, is described and illustrated. Trichocentrum loyolicum is compared with T. pulchrum, from which it mainly differs by the ...
Phylogenetic reassessment of Acianthera (Pleurothallidinae: Orchidaceae)
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 ...
Nomenclatural notes in the Pleurothallidinae (Orchidaceae): Phloeophila
Two of us found some years ago that Phloeophila nummularia, type species of the genus Phloeophila, was placed in a molecular phylogentic study in Pabstiella. In this article, we show with the inclusion of new sequences of ...
The authors presents 77 species new to science, distributed from Mexico, through Central and South America, as far as Argentina. They are distributed in Colombia (33), Peru (27), Ecuador (15), Costa Rica (5), Brazil (3), ...
