The radiation of angiosperms is associated with shifts among pollination modes that are thought to have driven the diversification of floral forms. However, the exact sequence of evolutionary events that led to such great ...

Martinella has traditionally included two species, Martinella iquitoensis and Martinella obovata, that are characterized by the presence of interpetiolar ridges surrounding the stems and minute prophylls of the axillary ...

Areas of endemism characterize geographical regions by their unique biotas, providing the basis for studies on the ecological and historical drivers of these biologically distinct units. Tribe Bignonieae (Bignoniaceae) are ...

Extinction risk has not been evaluated for 96% of all described plant species. Given that the Global Strategy for Plant Conservation proposes preliminary conservation assessments of all described plant species by 2010, ...

A pollen morphology study of 10 Brazilian native species of Fridericia (Bignoniaceae) from forest fragments was performed using light microscopy and scanning electron microscopy, in search of new characters that might ...

A recent taxonomic treatment of Adenocalymma resulted in nomenclatural changes associated with 47 names and 24 species. Seven emendations, 16 new synonyms, 29 typifications (24 of which are lectotypifications), 4 ...

The influence of ecological traits to the distribution and abundance of species is a prevalent issue in biodiversity science. Most studies of plant community assembly have focused on traits related to abiotic aspects or ...

Leaves have undergone structural modifications over evolutionary time, and presently exist in many forms. For instance, in Fabaceae and Bignoniaceae, leaf parts can be modified into tendrils. Currently, no data are available ...
