Rolfe, R.A. (1883) J. Bot. 21 : 202.
Usually grows into a small tree but also flowers and fruits as a shrub.
Twigs, petioles and leaves produce a copious milky exudate when cut or damaged. Leaf blades elliptic to obovate, about 10-33 x 5-13 cm, petioles about 0.5-2 cm long. One leaf of each pair of leaves is usually much smaller than the other. Lateral veins about 12-15 on each side of the midrib, curving but not forming definite loops inside the blade margin. Numerous peg-like glands or processes visible between the petioles and twigs. Short, erect, fleshy hairs usually visible on the underside of the leaf blades.
Flowers about 4-7 cm diam. Calyx tube about 18 mm long, lobes about 5 mm long. Corolla tube about 9-24 mm long, lobes about 10-40 mm long. Anthers sessile, about 3 x 1 mm, apex acuminate, base sagittate, attached to the inner surface of the corolla tube about 2-7 mm from the top. Carpels free or slightly connate at the base. Style glabrous, about 19 mm long. Stigma capitate.
