Sparingly branched vines; stems brownish, puberulent and sparsely pubescent with trichomes ca. 1.5 mm long. Leaves 5-foliolate, rachis 4-10 cm long, sparsely sericeous; leaflets oblong-elliptic to obovate, 1-5 cm long, 0.6-3.0 cm wide, en- tire, obtuse mucronulate, base rounded to cuneate, discolorous, micropunctate, adaxial surface green, puberulent, abaxial surface whitish, lannose and puberu- lent; stipules lanceolate to linear, 3-10 mm long, 1-3 mm wide, attenuate, entire to setose-denticulate, puberulent.

Note
|
It is readily distin- guished from the other species occurring in Central America by its 5-foliate leaves and wide fruits. In the province of Esmeraldas, Ecuador, this species is called "chupa-chupa," and its leaves are used to treat skin eruptions. No local names or uses have been recorded from Panama. Though the type specimen in Jussieu's herbarium is marked "Peru," it was probably collected from present-day Ecuador, since no material has been re- corded from Peru.
