Systematics Section Siddall, Nicolle [1], Porter-Utley, Kristen E. [2], McLean, Anna [2]. Untangling the passionflower vines: preliminary insights on the phylogeny of Passiflora subg. Decaloba based upon trnL-F sequences. Passionflowers (genus Passiflora) are vines, lianas, and trees known for their incredible morphological diversity, stunningly beautiful flowers, and edible fruits. Passionflowers allure a variety of different pollinators including bats, hummingbirds, butterflies, bees, and wasps. Passionflower butterflies also use Passiflora as host plants, and the relationship between these two groups of organisms is a classic example of co-evolution. The genus is currently composed of five subgenera: Astrophea, Decaloba, Deidamioides, Passiflora, and Tetrapathea. Due to its economic importance, subg. Passiflora has been the focus of most scientific research in the genus while the equally fascinating and species rich subg. Decaloba has been largely ignored; recently published revisionary studies of Passiflora have included at most 35 species from subg. Decaloba. There are many rare species in the subgenus that are currently recognized as threatened or endangered, and it is the largest lineage in the genus possessing species found in both the New and Old World. I present here a preliminary phylogenetic analysis of the subgenus based upon the gene sequences of trnL-F. These sequence data will also be combined with sequences of three other genes (ncpGS, ndhF, and ITS) and used in a separate phylogenetic analysis of the subgenus (see oral presentation by Porter-Utley, et al.).
