Exudate rapid and copious.
Petioles and twigs produce a milky exudate. Bristle-like hairs (stipules) wedged between the base of the petiole and the twig. Leaf blades about 8-15 x 4-6.5 cm, petioles about 0.4-0.8 cm long. Lateral veins about 9-11 on each side of the midrib. Midrib depressed on the upper surface. Both the upper and lower surfaces of the leaf blades hairy.
Inflorescence about 4-5 cm long, shorter than the leaves. Flowers about 20-30 mm diam. Calyx lobes about 2-5 mm long, ciliate, glabrous to densely puberulent. Five ovate glands each about 0.5-0.6 mm long attached to the inner surface of the calyx lobes, +/- one per lobe. Corolla tube subcylindrical to campanulate, constricted at the orifice, about 5-6.5 mm long, lobes narrowly obovate to obovate, about 10-20 mm long, puberulent. Corona fimbriate, about as long as the stamens. Staminal filaments less than 1 mm long, almost as wide as the base of the anther. Anthers about 6 mm long, broad at the base and tapering to the apex. Ovaries about 1.5 mm long, glabrous. Style about 7 mm long.
Cotyledons cordate 12-15 x 13-15 mm, apex acute or obtuse. First pair of leaves lanceolate, about 25-30 x 8-10 mm, margins smooth, hairs present at least on the midrib and lateral veins on the underside. At the tenth leaf stage: leaves lanceolate or ovate, apex acuminate, base cuneate, both the upper and lower surfaces hairy at least along the midrib; very small oil dots may be just visible with a lens; petioles and stem clothed in short pale hairs.
