Revision of Passiflora Subgenus Decaloba ... - Passion Flowers

undertaken. In this revision, the P. suberosa and P. coriacea species complexes
were studied in detail and specific entities redefined based on morphological and
molecular analyses (using phenetic and cladistic methods). A key, descriptions,
distribution maps, and illustrations are included in this revision, along with
cladistic analyses and a discussion of biogeography and ecology. Close
attention was paid to pollination biology in order to attempt to understand the
forces that led to a shift from hymenopteran (e.g., P. juliana J. M. MacDougal) to
hummingbird (e.g., P. viridiflora Cav.) pollination. Where possible, the
hymenopteran pollinators and Heliconiinae herbivores were identified (from the
literature) in order to investigate the hypothesized coevolutionary relationship
between the Heliconiinae and Passiflora.
