Diversification and convergence of flower shapes in the Neotropical plant genus Drymonia (Gesneriaceae).

Drymonia is one of the most morphologically variable and largest genera within the Neotropical members of the flowering plant family Gesneriaceae. The traditional classification of Drymonia has been changed based on phylogenetic studies that strongly support the convergence of floral traits associated with anti-bee or bird pollination. Molecular sequence data were generated from the nuclear ribosomal (nrDNA) internal and external transcribed spacer regions (ITS and ETS), and the chloroplast (cpDNA) matK-R intergenic spacer. Field studies were also conducted to better understand the role of bird and bee pollinator interactions. Pollen dosage studies were conducted as a basis to predict specific pollinators for campanulate, urceloate, laterally compressed, and hypocyrtoid corolla shapes. Our results suggest that pollen dosage counts can be used to predict pollinators.
