Mucuna pachycarpa Parreno ex Wilmot-Dear (1991b) 221, f. 2, map 1. — Type: BS 89471 (Ramos & Edaño) (holo A), Mindanao, Cota bato prov., Nupol, 18 Apr. 1932.

Distribution — Malesia: Philippines: Mindanao.

Notes — E.P. Parreno described this species as part of his revision of Mucuna of the Philippines for a MSc thesis at the University of Kentucky. This manuscript was never published. According to Wilmot-Dear (1991b) Harry Wiriadinata was about to publish the description of Parreno’s new species in the Journal of Japanese Botany , however, also that never oc- curred. So Wilmot-Dear was the first to published the name of M. pachycarpa , however, at that time a latin description was needed. So the name was not valid published. Here we validate the name by reference to the description by Wilmot-Dear.

Mucuna pachycarpa is in several aspects rather similar to M. longipedunculata which differs in: the narrower leaflets (4.5– 10 cm wide), longer inflorescences (1–7 m long), sutures of the pods which are not thickened.
