Medium-sized to large buttressed tree. Young twig, panicle, leaf bud, stipule outside (glabrescent or shortly pubescent within), petiole beneath, leaf beneath and midrib above sparsely persistently pale brown scabrid tomentose. Twig 2-2.5 mm ø apically, terete, ribbed below the stipule scars, becoming smooth; stipule scar c. 2 mm long, c. 0.5 mm thick, pale, cuneate, slightly falcate, horizontal or slightly ascending. Leaf bud 5-8 by 4-6 mm, ovoid, subacute. Stipule to 15 by 5 mm, hastate, acute. Leaves 12-24 by 5.5-11 cm, broadly oblong to ovate, +-thinly coriaceous; base obtuse; acumen to 1.2 cm long; nerves 15-19 pairs, prominent, at 60°-70°, curved distally; short secondary nerves frequently present; tertiary nerves prominent, well spaced, at 90° to nerves; midrib prominent, terete beneath, applanate but evident above; petiole 1-1.5 cm long, short. Panicle to 22 cm long, terminal or axillary, terete or ribbed, lax, regularly alternately singly or doubly branched, the branchlets bearing to 7 secund flowers; bracts and bracteoles to 7 by 3 mm, ovate, acute, pubescent outside, glabrous within, not at first caducous. Flower bud to 8 mm long, narrowly ovoid, acute. Calyx shortly densely pale grey-brown pubescent outside, glabrous within; 3 outer lobes longer, ± deltoid to ovate, subacute; 2 inner lobes shorter, narrowly deltoid to ovate, acute, acuminate. Petals pale cream-yellow, narrowly oblong, densely pubescent on parts exposed in bud. Stamens 15, the 5 inner an anther's length longer than the others; filaments basally expanded, abruptly tapering and filiform distally; anthers oblong; appendage to connective reaching to style apex on 5 inner stamens, more than twice as long as anthers, curved but not reflexed. Ovary and stylopodium pyriform, densely pubescent in the distal half, shortly densely pubescent basally; style as long as ovary and stylopodium, filiform, glabrous. Fruit subsessile. Calyx glabrescent; 3 longer lobes to 5 by 0.8 cm, spatulate, subequal, to 3.5 mm broad above the to 1.5 by 1.2 cm ovate glabrous shallowly saccate thickened base; 2 shorter lobes to 25 by 1.5 mm, linear, similar at base.
