It usually has a single purplish stem and sparse branching. Young stems are four-angled, becoming rounded with age. The crushed foliage has an unpleasant odor. Compound alternate leaves have four to six pairs of glabrous leaflets and a gland near the base of the petiole. Leaflets are ovate to ovate-lanceolate, pointed at the tip and rounded at the base.
