The phylogenetic relationships of some Neotropical plant groups have proved to be different
from expectation assuming plate tectonics as the underlying model, and these unanticipated …

A revised and updated classification for the families of flowering plants is provided. Many
recent studies have yielded increasingly detailed evidence for the positions of formerly …

Phylogenetic relationships among 88 genera of Rosaceae were investigated using
nucleotide sequence data from six nuclear (18S, gbssi 1, gbssi 2, ITS, pgip, and ppo) and …

The present classification of extant flowering plants (Magnoliopsida) updates and revises
those presented previously by bringing together the vast majority of new information …

Eudicots and their currently recognized major subclades are characterized as to floral
structure (including some “embryological” features) based on ca. 3000 original publications …

Floral features used for characterization of higher-level angiosperm taxa (families, orders,
and above) are assessed following a comparison of earlier (precladistic/premolecular) and …

A methodology for characterizing vegetal taxonomic groups using microextraction-assisted
voltammetry of microparticles is described. It is based on recording the voltammetric …

A methodology for characterizing vegetal taxonomic groups from the voltammetric
fingerprints of polyphenolic components of seeds is described. It is based on recording the …

Background: Mesoamerica is one of the most important biodiversity hotspots on the planet.
Despite significant efforts made over two centuries to contribute to the floristic knowledge of …
