Vast, prominently buttressed tree. Twig, panicle, leaf bud, stipule, petiole and nerves beneath densely shortly evenly pink-brown pubescent. Twig c. 2.5 by 1 mm ø apically, compressed and ridged at first, becoming terete, much branched; stipule scars c. 1.5 mm long, pale, linear, horizontal. Leaf bud to 4 by 3 mm, ovoid, compressed, slightly asymmetrical, subacute. Stipule to 12 by 5 mm, ovate-lanceolate, fugaceous. Leaves 7-12 by 4-7 cm, oblong, thinly coriaceous, silver to cream lepidote beneath; base broadly cuneate; acumen 5-10 mm long, broad; nerves 16-24 pairs, dense, straight, at 50°-60°; midrib slender, prominent beneath, depressed above; tertiary nerves densely scalariform, slender, ± obscure; petioles 1-1.5 cm long, slender. Panicle to 8 cm long, terminal or axillary, somewhat compressed and ribbed; regularly singly branched, branchlets to 2 cm long, bearing to 8 close secund flowers; bracteoles to 5 mm long, lanceolate, acute, caducous. Flower bud to 7 by 2 mm, lanceolate. Calyx shortly pubescent outside, glabrous within; 3 outer lobes deltoid-ovate, acute; 2 inner lobes smaller, ovate, acuminate, thinner.
