Medium-sized to large tree. Twig, leaf bud, petiole, both surfaces of midrib, leaf beneath and panicle densely persistently scabrid gold tomentose; leaf above puberulent or glabrescent. Twig 2-2.5 mm ø apically, slightly compressed, becoming terete, much branched; stipule scars narrow, almost horizontal, amplexicaul. Leaf bud 3-7 by 1.5-3 mm, ovoid, obtuse or subacute. Stipule to 3.5 by 1.3 cm, hastate, acute; base slightly constricted; relatively persistent. Leaves 10-17 by 4-7.5 cm, ovate or elliptic, somewhat coriaceous; base obtuse; acumen to 1.3 cm, long, narrow; margin frequently narrowly revolute; nerves 12-15 close slightly curved pairs, at 45°-50°, with hispid axillary domatia; tertiary nerves densely scalariform, at c. 90° to the nerves; petiole 1-1.3 cm long, short. Panicle to 14 cm long, singly branched, terminal or axillary, terete. Flower bud to 8 by 3 mm, lanceolate. Sepals narrowly deltoid, subequal, densely pubescent on parts exposed in bud. Petals cream tinted with pink, lanceolate, densely pubescent on parts exposed in bud. Stamens 15, the inner 5 slightly the longest; filaments compressed, connate, abruptly tapering below the broadly ellipsoid anthers; appendage to connective aristate, c. 4 x length of anthers. Ovary ovoid, glabrous; style and stylopodium spindle-shaped, glabrous. Fruit calyx glabrescent; 3 longer lobes by 17 by 2.5 cm, subequal, oblong-spatulate, obtuse, c. 1.3 cm broad above the c. 1.3 by 1.5 cm thickened deeply saccate base, adpressed to and hiding the nut; 2 shorter lobes to 12 by 1 cm, spatulate, similar at base. Nut to 2 by 1.8 cm, ovoid, abruptly constricted below the to 1 cm long narrow-conical apex; style remnant acute, densely shortly buff pubescent.
