Using a time-calibrated phylogenetic hypothesis including 768 Gesneriaceae species (out
of~ 3300 species) and more than 29,000 aligned bases from 26 gene regions, we test …

Floral monosymmetry and asymmetry are traced through the angiosperm orders and
families. Both are diverse and widespread in angiosperms. The systematic distribution of the …

• Premise of study: Flowering traits can sometimes be overemphasized in taxonomic
classifications. The fused and completely differentiated papilionate floral organs in the …

Background Flowers have an amazingly diverse display of colors and shapes, and these
characteristics often vary significantly among closely related species. The evolution of …

The Gesneriaceae is a family known for convergent evolution of complex floral forms. As a
result, defining genera and resolving evolutionary relationships among such genera using …

Besleria, a genus of perennial herbs, shrubs, or small trees growing in the understorey of
rainforests, is one of the largest genera of neotropical Gesneriaceae, with over 165 species …

Background Bilateral symmetry flower (zygomorphy) is the ancestral state for Gesneriaceae
species. Yet independent reversions to actinomorphy have been parallelly evolved in …
