Gland between proximal pair of lfts only; lfts 3-5 pairs, the distal pair 1.8-3.5 cm, the margin revolute; both faces of lfts loosely reticulate, the tertiary veinlets prominulous; androecium of var. organensis; gynoecium glabrous.—Collections: 6.

This variety, fully disjunct from the rest of the species, is distinguished from var. organensis, of which it has essentially the flower and fruit, by the combination of relatively few, reticulate leaflets, a solitary petiolar gland, and glabrous ovary.
