Medium-sized or large buttressed tree with dark fissured bark. Young twig, panicle, bud, stipule outside, petiole and nervation beneath densely persistently purplish brown scabrid tomentose; stipule inside, midrib above and leaf beneath shortly evenly so. Twig to 2.5 mm ø apically, ribbed at first, becoming terete, rugulose; stipule scars 2 mm long at first, 0.5 mm thick, pale, slightly descending, falcate or horizontal, obscured by tomentum. Bud 4-6 by 3-5 mm, ovoid, subacute. Stipule to 14 by 5 mm, oblong-elliptic, subacute. Leaf 9-17 by 4-9 cm, oblong-ovate to oblong-obovate; base obtuse; acumen to 9 mm long, broad; margin frequently somewhat revolute; nerves variable, 14-19 pairs, slightly curved, prominent beneath, at 60°-75°; tertiary nerves scalariform, slightly diagonal to nerves; midrib terete and prominent beneath, evident but somewhat depressed above; petiole 1.3-2.3 cm long. Panicle to 12 cm long, terminal or axillary, lax, terete or slightly compressed; regularly alternatively singly or doubly branched, branchlets bearing to 6 distichous flowers; bracteoles to 4 by 3 mm, ± elliptic, subacute, pubescent outside, glabrous within, fugaceous. Flower bud to 7 by 4 mm, broadly ovoid. Calyx densely rust-brown pubescent on parts exposed in bud; lobes subequal, ovate; 3 outer lobes obtuse, 2 inner acute to subacuminate. Petals yellow, oblong, obtuse, densely long gold-brown pubescent on parts exposed in bud. Stamens 15, the 5 inner somewhat longer and reaching the style apex; filaments much twisted, tapering gradually; anthers subglobose; appendage to connective very short, becoming reflexed. Ovary and stylopodium conical, densely pale grey pubescent in the distal half, glabrous at base; style short, cylindrical, glabrous. Fruit calyx shortly sparsely fulvous-brown to buff pubescent; 3 longer lobes to 10.5 by 2.5 cm, spatulate, narrowly obtuse, to 4-7 mm broad above the to 1.4 by 1 cm elliptic to ovate saccate thickened base; 2 shorter lobes subequal, to 5 by 0.4 cm, linear, acute, similar at base. Nut to 2.3 by 1.5 cm, ovoid, persistently shortly evenly buff fulvous pubescent; style remnant acute.
