Large buttressed tree. Leaf bud, stipule and panicle persistently shortly pale gold-brown pubescent; nervation, petiole and young twig sparsely dotted with minute caducous hair tufts. Twig 1.5-2.5 mm diameter, terete at first smooth, becoming flaky; stipule scars pale, short, narrow, horizontal. Bud 4-8 by 2-3.5 mm, ovoid, acute. Stipule to 13 by 4 mm, hastate, acute. Leaves 9-15 by 4-5.5 cm, ovate, +/- thinly coriaceous, frequently subequal; base obtuse to broadly cuneate; acumen 0.6-1.2 cm long, narrow; nerves 8-9 pairs, slender but prominent beneath, at c. 40-50 degrees, straight, slightly curved at the margin, occasionally with a few glabrous domatia; tertiary nerves very slender, densely scalariform, diagonal to the nerves; midrib narrowly depressed above, prominent beneath; petiole 1.3-1.8 cm long. Panicle to 15 cm long, terminal or axillary, ribbed or slightly compressed, lax; doubly or trebly branched, the branchlets bearing to 19 second flowers; bracteoles to 4 by 2.5 mm, oblong, subacute, shortly densely pale yellow-brown to pubescent fugaceous. Flower bud c. 7 by 3.5 mm, ovoid, subacute. Calyx densely pale yellowish buff pubescent outside, glabrous within; lobes subequal, deltoid, obtuse, the 2 inner slightly narrower. Petals pale yellow, oblong, obtuse, densely pubescent on parts exposed in bud. Stamens 15, the inner 5 slightly longer than the other 10; filaments expanded at base, abruptly narrowing distally; anthers broadly oblong; appendage to connective c 2 times the length of anther, setose towards the apex, the inner 5 reaching the style apex. Ovary and stylopodium ovoid to conical, shortly densely pubescent; style glabrous, slightly shorter than ovary and stylopodium. Fruit subsessile. Calyx sparsely pubescent, more densely so at base; 3 longer lobes to 9 by 1.5 cm, spatulate, narrowly obtuse, c. 4 mm broad above the c. 8 by 11 mm rounded thickened saccate base; 2 shorter lobes to 5 by 0.5 cm, linear, similar at base. Nut c. 1.4 by 1.2 cm, broadly ovoid, obtuse or with a short acute style remnant, densely pale buff tomentose. [from Flora Malesiana]
