Phaseolus magnilobatus Freytag & Debouck (2002: 167) [clade A; sect. Xanthotricha A. Delgado].

TYPE: GF Freytag 81-Mex-22 (HOLOTYPE: US-3386752) .

The type is material grown in screenhouse in Mayagüez from seed originally collected in SE Jalisco, Mexico; several isotypes not seen during this study were made from the same gathering. A couple of collections from S Durango complete the current range, thus suggest it as endemic. It has been proposed as a synonym of P.hintonii, a move that is not done here (because of the leaflet and seed traits) pending on additional collections and cross comparisons based on living materials.

Specimens: MEXICO. Durango: DG Debouck 402 (K), HS Gentry 22086 (NA).
