Small tree. Young twig and petiole shortly buff caducous pubescent; panicle, stipule (outside only), and leaf bud persistently shortly evenly cream pubescent. Twig 2-3 mm ø apically, straight, stout, terete; petiole scars large, orbicular, swollen; stipule scars short, indistinct. Bud to 3 by 1.5 mm, conical. Stipule c. 8 by 3 mm, fugaceous, narrowly deltoid, cupped, subacute. Leaves 12-25 by 4-7 cm, bright red at first, oblong-lanceolate, thinly coriaceous, slightly bullate; base obtuse or broadly cuneate; acumen to 1 cm long, deltoid; margin sometimes slightly revolute; nerves 9-13 pairs, prominent beneath, at 40°-50°, curving and continuing parallel with the margin distally, sometimes anastomosing to form an indistinct intra-marginal nerve; tertiary nerves remotely scalariform; petiole 8-15 mm long, c. 1.5 mm ø, short. Panicle to 10 cm long, terminal or 2-axillary to ramiflorous, angular; somewhat irregularly doubly branched, branchlets to 1.5 cm long, zigzag, bearing to 9 flowers; bracteoles minute, fugaceous. Flower bud to 4.5 by 1.5 mm, lanceolate, acute. Calyx shortly puberulent outside, glabrous within; lobes ovate, the inner 2 lobes thinner, more constricted at the base. Petals cream-yellow, linear, shortly pubescent on parts exposed in bud, imbricate and cupped at the base, spreading and twisted distally. Stamens 15, in 3 unequal verticils; filaments broad at base, tapering and filiform distally; anthers oblong; appendage to connective 1-2 times length of anther, ciliate towards the apex, reaching the base of the style. Ovary ovoid-conical, glabrous at base, shortly pubescent apically, tapering into the stylopodium; style short, glabrous. Fruit calyx lobes c. 1 mm long and broad, subequal, broadly ovate, thickened, shortly pale fulvous caducous pubescent outside, glabrous within, not adpressed to the nut but prominently saccate. Nut c. 2.0 by 1.3 cm, obovoid, subacute, slightly striated longitudinally, densely shortly persistently pale fulvous pubescent.

A canopy tree in mixed dipterocarp forest on hills; growing on clay soils over shale and basic volcanic rock; usually at low elevations but occasionally to 1,000 metres.
