Note
|
Paullinia morii is distinguished by its pinnately 7-foliolate leaves with narrow, prominently veined leaflets and by its glabrous, 3-winged fruits which are mostly rounded at the apex. It is described in honor of its collector Scott Mori. The species is known from a single collection made in Panama in a region bordering tropical wet forest and premontane rain forest. The collection made in February has full-sized but immature fruits.
