The variety consists of two minor races: one with relatively large leaflets softly villosulous beneath, known from Moji and S. Jose dos Campos; and one corresponding exactly with Sello's type, with smaller leaflets glabrous and setose beneath, collected subsequently only at Butantan. They are similar, however, in their few leaflets and small flowers, collectively different in these characters from the more northern var. acutifolia.
