Abstract

In this study we transfer Pleonotoma albiflora to Adenocalymma based on a robust molecular phylogeny based on wide sampling of taxa and molecular markers. Morphological studies provide additional support for the placement of this taxon within Adenocalymma. Here, we make the new combination Adenocalymma albiflorum (Bignonieae, Bignoniaceae), and discuss the morphology and distribution of the species. We also provide a detailed description, illustrations, photographs, and a distribution map for this taxon.
