    Variety Description - Vegetatively intermediate between the two preceding, the stems strongly angulate or not, the lfts in size and outline more often like those of var.jaliscensis; leaf-formula ii-iii/12-22; pod ± 5-12 cm long, the replum 2-5.5 mm, the valves ± 1.5-2 mm wide, all either unarmed or remotely short-aculeate.

    Distribution and Ecology - In thickets or in open places within deciduous woodland and palm-forest, sometimes on rocky sea-shores, below (?) 400 m, scattered along the Pacific lowlands of Mexico from Sinaloa to Colima.

  • Discussion

    I have not found any certain way of distinguishing this taxon in the flowering condition, and am doubtful whether the nearly unarmed fruit is reliably diagnostic.
