Abstract:
A phylogenetic analysis of Passifloraceae sensu lato was performed using rbcL, atpB, matK, and 18S rDNA sequences from 25 genera and 42 species. Parsimony analyses of combined data sets resulted in a single most parsimonious tree, which was very similar to the 50% majority consensus tree from the Bayesian analysis. All nodes except three were supported by more than 50% bootstrap. The monophyly of Passifloraceae s.l. as well as the former families, Malesherbiaceae, Passifloraceae sensu stricto, and Turneraceae were strongly supported. Passifloraceae s.s. and the Turneraceae are sisters, and form a strongly supported clade. Within Passifloraceae s.s., the tribes Passifloreae and Paropsieae are both monophyletic. The intergeneric relationships within Passifloraceae s.s. and Turneraceae are roughly correlated with previous classification systems. The morphological character of an androgynophore/gynophore is better used for characterizing genera grouping within Passifloraceae s.s. Other morphological characters such as the corona and aril are discussed.
