Relationships of subgenus Decaloba to the other four Passiflora subgenera (Astrophea, Deidamioides, Tetrapathea, and Passiflora) are investigated, as are relationships among the eight supersections within subgenus Decaloba. Results indicate that subgenus Deidamioides is not monophyletic, with section Tryphostemmatoides resolved as sister to subgenus Astrophea, sections Tetrastylis, Polyanthea, and Deidamioides forming a clade sister to subgenus Passiflora, and section Mayapathanthus resolved as part of subgenus Decaloba. Subgenus Astrophea + subgenus Deidamioides (section Tryphostemmatoides) is the most basally branching lineage in the genus followed by subgenus Passiflora + subgenus Deidamioides (sections Tetrastylis, Polyanthea, Deidamioides). The Old World subgenus Tetrapathea is supported as the sister to subgenus Decaloba. Subgenus Decaloba is monophyletic and contains seven major lineages that generally correspond to currently recognized supersections. Within subgenus Decaloba, supersection Pterosperma is most basally branching, followed by supersection Hahniopathanthus + P. obovata. The New World species Passiflora multiflora, the type of supersection Multiflora, is resolved as sister to a monophyletic Old World supersection Disemma. The remainder of the former supersection Multiflora is paraphyletic with respect to supersection Auriculata. Supersections Cieca, Bryonioides, and Decaloba are monophyletic. Within supersection Decaloba, two main clades are resolved: 1) section Xerogona + section Decaloba pro parte and 2) the remainder of section Decaloba. The molecular phylogeny supports a New World origin for Passiflora, with two independent radiations to the Old World. Morphological synapomorphies are discussed for the major clades, revealing frequent gains and losses in several important characters. } }
