A new pluriannual species of Phaseolus has been found on the Pacific slope of central Costa Rica, in an intact wet forest of the San José province. It could belong to the section Brevilegumeni of the genus, and differs from P. oligospermus by the round based leaflets with central permanent variegation, multi-flowered pseudoracemes with cup-shaped round primary bracts, flowers with white wings and light pinkish standard, slightly falcate pods with three lentil-like seeds. Its ecological niche is wetter and with a shorter dry season as compared to that of the latter species. Only two populations of the new taxon are known to date in this part of Costa Rica.
