Phaseolus hygrophilus Debouck (2011: 54) [possibly in clade A and sect. Brevilegumeni Freytag].

TYPE: DG Debouck & R Araya Villalobos 3172 (HOLOTYPE: INB-4026793; ISOTYPES: BRIT, CR, F, FI, G, GH-351974, INB, K-780075, MEXU, MICH-1229077, NY-1365122, P, UC, USJ) .

As indicated in the original publication (Salcedo-Castaño et al. 2011, p. 53), the series of herbarium specimens on which the holo- and isotypes were made was from a cutting grown in the Popayán station of CIAT in Colombia (Fig. 3). It seems to be an endemic species of the premontane rain forests of Costa Rica at 1300–1600 m (Debouck et al. 2020). It is not mentioned in “Vascular Plants of the Americas” (2020).

Specimens: COSTA RICA. San José: DG Debouck 3173 (USJ-88816), DG Debouck 3370 (USJ-111489), DG Debouck 3371 (USJ-111736).
