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 ...
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 ...
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 ...
Prosthechea ionophlebia and P. chacaoensis two different species, but which is which?
(2007)
Prosthechea ionophlebia and P. chacaoensis can be distinguished using several characters. Based on classical literature, the only diagnostic differences between P. chacaoensis and P. ionophlebia are flower size 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 ...
Taxonomy in watercolor: the Specklinia endotrachys group, part 2
Taxonomie in Aquarell: die Specklinia-endotrachys-Gruppe, Teil 2
(2013)
in the last decade orchid systematics has focused especially on assessing evolutionary relationships among species and species groups, in an attempt to produce a solid phylogenetic framework for the family. While in general ...
Two new species of Echinosepala (Orchidaceae: Pleurothallidinae)
(2017)
We describe and illustrate two new species of Echinosepala from Costa Rica, they are placed within a phylogenetic framework of the genus, and compared to their closest relatives. A short resume of the genus’ history is ...
