known only from Panama and Colombia.

Note

It is easily distinguished from other Pentagonia of Panama except P. brachyotis by its pin- natifid leaves and petioles bearing large foliaceous auricles. Among the Choco the fruits are eaten, and the leaves and fruits are "taken in a tea as a blood purifier" (fide Duke).
