A cream or pale brown layer may be visible beneath the subrhytidome layer but outside the outer blaze.
Glands normally visible on the upper surface of secondary axes near the point of attachment of the terminal leaflets. A raised gland normally visible on the upper surface of the compound leaf petiole, about 1-4 cm from the base. Leaflet blades about 2-8 x 1.5-2.5 cm.
Pedicels about 4-5 mm long, almost as long as the corolla. Pedicel, calyx and corolla pubescent on the outer surface. Peduncles about 3-6 cm long. Corolla tube about 4 mm long, corolla lobes about 1-1.5 mm long. Staminal filaments about 5-10 mm long, fused to form a tube in the lower half, but free in the upper half. Ovary stalked, ovules about 15.
Pods flat, about 10-15 mm wide, but often constricted between the seeds, usually in a flat spiral before maturity, but becoming twisted at opening. Pods orange-brown on the inner surface. Seeds +/- turgid, about 6 x 5 mm, marked by a pleurogram.
At the tenth leaf stage: leaflet blades ovate, apex acuminate, base cuneate, unequal-sided, upper surface hairy along the midrib; petiole and rhachis of compound leaf clothed in short tortuous hairs; glands normally visible on the upper surface of the secondary axes near the point of attachment of the terminal leaflets. Stipules linear-triangular, hairy. Stem and terminal bud clothed in pale brown hairs. Seed germination time 11 to 30 days.
