An international research group that aims at improving the knowledge of the genus Passiflora. We are particularly interested in augmenting knowledge of taxonomy and phylogeneic relationships within the genus. Although Passiflora is a medium-sized genus of 520 species, it is by far the largest genus in the Passifloraceae and is amazingly diverse in its morphology.

During the coming four years we will focus our research specifically on subgenus Decaloba, which is currently recognized with 235 species, with an estimated 20–35 additional species new to science.
