Evolution of Seed Dispersal Modes in the Orchidaceae: Has the Vanilla Mystery Been Solved?
Orchid seeds are predominantly wind-dispersed, often developed within dry, dehiscent fruits that typically release millions of dust-like seeds into the air. Animal-mediated seed dispersal is a lesser-known phenomenon in the family and predominantly occurs in groups belonging to early-diverging lineages bearing indehiscent, fleshy fruits with hard, rounded, dark seeds. In... -

Acianthera hagsateri (Pleurothallidinae), a new species from the sub-andean forest of Colombia.
A new species of Acianthera from the relict cloud forests of Valle del Cauca, Colombia is described and illustrated. This new species, Acianthera hagsateri, morphologically resembles A. geminicaulina, A. decurrens, and A. erythrogramma, but differs from them by its shorter plants and stems, the elliptic and obtuse smaller leaves, the... -

Phylogenetic comparative methods improve the selection of characters for generic delimitations in a hyperdiverse Neotropical orchid clade
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 difficult to assess. Phylogenetic comparative methods help to evaluate the convergent evolution of a given morphological character, thus...Bogarín, Diego ; Pérez-Escobar, Oscar A. ; Karremans, Adam P. ; Fernández, Melania ; Kruizinga, Jaco …

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 low variability in traditional molecular loci. Furthermore, biological phenomena responsible for topological incongruence such as Incomplete Lineage Sorting (ILS) and hybridisation...Alejandro Pérez-Escobar, Oscar ; Bogarín, Diego ; Schley, Rowan ; Bateman, Richard M. ; Gerlach, Günter …
