Begonia quinquealata

Begonia quinquealata is an endemic species of "Begonia" discovered in Salakot Falls, Napsan, Puerto Princesa City, in northern Palawan, Philippines. This species, along with "B. suborbiculata" Merr., are the only two known species in the Philippines with 5-winged capsules. Unlike any other member of Begonia sect. "Baryandra", "B. quinquealata" is very distinctive for being a densely hairy herb with long creeping rhizomes. It differs also from "B. suborbiculata" in that it has thickly chartaceous, widely ovate leaves that have uniformly green upper leaf surface, densely velutinous, with denticulate leaf margin, outer tepals, and red scabrous ovary and capsules.
