Common name



Bark dark brown. Branches supple but tough and difficult to break.


Leaf blades about 8-20 x 3.5-9.5 cm. Midrib and main lateral veins raised on the upper surface of the leaf blade. One or two raised glands may be present on the upper surface at the junction of the leaf blade and petiole. Freshly cut twigs may produce a sticky exudate. Pith of older twigs generally red.


Calyx and corolla ferruginous-pubescent on the outer surface. Calyx about 7-8 mm long. Corolla about 10-12 mm long. Disk consists of five globular glands. Ovary densely hairy. Stigmas +/- foliaceous.

At the tenth leaf stage: leaf blade obovate, apex acuminate, base cuneate, upper surface glabrous, midrib and lateral veins raised on the upper surface of the leaf blade; two glands present on the upper surface of the leaf blade at its junction with the petiole; petiole hairy towards the apex; stipules caducous, small, triangular, hairy. Seed germination time 19 to 905 days.
