Large tree with stout buttresses. All vegetative parts glabrous. Twig c. 3 mm ø apically, stout, much branched, terete, smooth; nodes prominent, with raised round petiole scar and c. 2-3 mm long straight pale linear ascending stipule scars (only visible on young twigs). Bud 4-7 by 1-1.5 mm, linear to falcate. Stipule to 10 by 3 mm, narrowly oblong, acute, caducous. Leaves 11-17 by 7-13 cm, broadly ovate to suborbicular, cream lepidote beneath, coriaceous; base obtuse or subcordate; acumen to 8 mm long; nerves 9-11 pairs, distant, arched, at c. 40°-50°; tertiary nerves sinuate, densely scalariform, slender; petiole 4-6 cm long. Panicle to 12 cm long, terminal or axillary, +-terete, densely shortly persistently pale buff pubescent, glabrescent; regularly singly branched, branchlets to 1.5 cm, short, bearing to 4 secund flowers; bracteoles to 4 mm long, oblong, puberulent, fugaceous. Flower buds to 20 by 4 mm, large, narrowly lanceolate, acute. Calyx shortly pubescent outside, glabrous within; lobes ovate, acute, the outer 3 slightly longer and narrower than inner 2. Petals cream, to 2.5 cm long, linear, pubescent on both surfaces. Stamens c. 55; filaments broad at base, tapering and filiform distally; anthers oblong, glabrous, the posterior lobes slightly smaller; appendage to connective somewhat shorter than anther but prominent, stout and setose. Ovary broadly ovoid, densely tomentose but for the glabrous base, abruptly tapering to a short broad trifurcate glabrous style; stigma minute. Fruit calyx lobes c. 1.5 cm long and broad, equal, deltoid, subacute, incrassate, sparsely pale grey-buff pubescent, the apices adpressed to the base of the nut.
