Twig c. 1.5 mm diameter apically, terete, ridged when young, much branched, slender, becoming glabrous, smooth; stipule scars short, horizontal, obscure. Bud 3-5 by 2-3 mm. compressed, broadly ovoid, subacute. Stipule to 10 by 3.5 mm, oblong to broadly hastate, obtuse, fugaceous. Leaves 8-14 by 3.5-5.5 cm. elliptic to ovale, thinly coriaceous, cream below in mature trees; base obtuse or broadly cuncate; acumen short, to 8 mm long; nerves 12-15 pairs, slender, curved towards margin, set at c. 40-55 ; tertiary nerves very slender, densely scalariform, obscure except in young trees; midrib narrow and depressed above and prominent beneath, in young trees beset from the base up more or less its length with lines of small, pale, scale-like domatia occasionally extending also on the nerves; petiole 1.0-1.5 cm long. Panicle to 14 cm long; terminal or axillary, terete, lax, slender, sparsely or densely evenly persistently pale brown to cream pubescent; regularly singly, rarely doubly, branched, branchlets short, bearing to 12 +/- secund flowers; bracteoles to 3 by 2 mm, elliptic, obtuse, shortly pubescent, fugaceous. Flower hud to 6 by 3 mm, fusiform, subacute. Calyx densely pale brown pubescent outside, glabrous within; 3 outer lobes narrowly ovate, obtuse; 2 inner lobes broadly ovate, shorter, shortly acuminate. Petals pale yellow, narrowly oblong, densely pale yellowish grey pubescent on parts exposed in bud. Stamens 15, the inner 5 twice as long as the others and reaching half the length of the style; filaments long, tapering gradually; anthers subglobose; appendage to connective short, becoming reflexed. Ovary and stylopodium ovoid, glabrous; style filiform, twice as long as ovary and stylopodium, glabrous. Fruit calyx glabrescent or persistently shortly pubescent at base; 3 longer lobes to 10 by 2 cm, spatulate, obtuse, c. 5 mm broad above the to 8 by 6 mm thickened elliptic shallowly saccate base; 2 shorter lobes to 5.5 by 0.3 cm, unequal, similarly saccate at base. Nut to 2 by 1 .3 cm, ovoid, densely pale buff pubescent; style remnant c. 2 mm long, tapering, acute. [from Flora Malesiana]
