Bud to 2 by 1.5 mm, small, globose to ovoid, obtuse. Stipule to 4 mm long, linear, fugaceous. Leaves 6-12 by 2-7 cm, coriaceous, +-ovate; base obtuse or broadly cuneate, usually unequal, decurrent to 1.5 mm along the petiole; acumen to 1 cm long, narrow; nerves 5-7 pairs, strongly curved, widely spaced, at 60°-70°, running parallel to the margin for a short distance distally; tertiary nerves distant, scalariform at the margin, reticulate near the midrib; petiole 1.2-2 cm long. Panicle to 8 cm long, terminal or axillary, slender, terete; somewhat irregularly doubly branched, branchlets to 1.5 cm long, short, frequently zigzag, bearing to 8 distichous flowers; bracteoles minute, fugaceous. Flower bud to 4.5 by 1.2 mm, lanceolate, acute. Calyx shortly pubescent outside, glabrous within; 3 outer lobes deltoid, acute; 2 inner lobes subequal to them, suborbicular, mucronate, thin. Petals yellow-brown with bright yellow margin, linear, puberulent on parts exposed in bud, imbricate in basal half, spreading and twisted distally when opened. Stamens 15, in 3 slightly unequal verticils; filaments broad and slightly gibbous at base, tapering and filiform distally; anther broadly oblong to subglobose; appendage to connective somewhat longer than anther, shortly ciliate towards apex. Ovary and stylopodium conical, glabrescent, tapering; style short, stout, glabrous. Fruit subsessile; calyx lobes c. 5 mm long and broad, equal, short, deltoid, subacute, glabrous, saccate and closely adpressed to the nut, margin slightly revolute.
