Untangling the passionflower vines: preliminary insights on the phylogeny of Passiflora subg. Decaloba based upon ITS sequences.
Passionflowers (genus Passiflora) are tropical vines that are widely known for their beautiful, complex flowers and delicious fruits. Passionflowers are also known to possess some of the most variable reproductive (flowers and fruits) and vegetative (leaves, stems, and roots) structures of all plants. The flowers of passionflowers are variable because they attract a wide variety of pollinators (e.g., bees, bats, and hummingbirds) and have floral structures that are adapted for these different types of pollinators. The plants also have a very close relationship with a special group of butterfly herbivores, appropriately called passionflower butterflies, and vary their leaves to avoid them. Throughout the course of the academic year our research has been focused on the systematics of a large (ca. 235 species) subgroup of passionflowers (Passiflora subgenus Decaloba). Subgenus Decaloba contains eight supersections, of which only two, Disemma and Cieca, have been tested for monophyly. We present here a preliminary phylogenetic analysis of subgenus Decaloba based on nuclear ribosomal internal transcribed spacer (ITS) data and including taxa that represent all eight supersections. This data will also be combined with data from three other genes (ncpGS, ndhF, and trnL-F) and used in a separate phylogenetic analysis of the subgenus (see oral presentation by Porter-Utley, et al.).
