Leaf blades about 20-50 x 3.5-8 mm, petioles 1-4 mm long, channelled on the upper surface. Leaf margin usually toothed but the teeth quite small, pale and visible only with a lens. Stipules caducous, small, short and triangular, about 0.5 mm long. Petioles and twigs emit a watery white to clear exudate.

Cotyledons obovate, about 13-14 x 7 mm, apex truncate. First pair of leaves linear to obovate. At the tenth leaf stage: leaf blade linear to obovate, about 30-35 x 7 mm, apex retuse, base obtuse or cuneate, petiole about 1 mm long. Lateral veins about 8, forming loops inside the blade margin. Seed germination time 168 days.
