Summary The Andean mountains of South America are the most species‐rich biodiversity
hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land …

Despite its relevance, the study of the inflorescence from a typological point of view
generally goes unnoticed in taxonomy, which is fundamental for the comparison of structural …

In angiosperms, genome size and nucleobase composition (GC content) exhibit pronounced
variation with possible adaptive consequences. The hyperdiverse orchid family possessing …

Recent phylogenomic analyses based on the maternally inherited plastid organelle have
enlightened evolutionary relationships between the subfamilies of Orchidaceae and most of …

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 …

Colombia is a major biodiversity hotspot, having one of the richest orchid floras in the world.
The country spans over a million square kilometers of land, hosting a multitude of different …

Although the evolutionary drivers of genome size change are known, the general patterns
and mechanisms of plant genome size evolution are yet to be established. Here we aim to …

The Neotropical realm hosts some of the Earth's most species-rich biodiversity hotspots, with
vascular epiphytes significantly contributing to this diversity, regionally accounting for up to …

The phylogenetic relationships within the Acianthera affinity are re-evaluated using
Bayesian analyses of nrITS and chloroplast matK sequence data. Emphasis is made on …

Pabstiella consists of c. 130 epiphytic species in the Neotropics. We present a phylogenetic
analysis based on nrITS, matK and trnH-psbA sequences from 59 species of the genus and …
