Characteristics

Large buttressed tree. Young twig and petiole densely evenly pale rufous caducous pubescent; leaf bud, panicles, sepals and parts of petals exposed in bud persistently so; leaves, stipules and ovary sparsely fugaceous pubescent; leaves pale pink-brown lepidote beneath. Twigs 1-2 mm ø apically, smooth, terete, becoming chocolate-brown; stipule scars slender, short, horizontal. Buds to 2 by 1 mm, small, ellipsoid. Stipules to 20 by 3 mm, narrowly elliptic, obtuse, not at first caducous. Leaves (3-)4-8(-12) by (1-)2.5-4.5(-5) cm, broadly lanceolate to elliptic, coriaceous; base obtuse or rarely broadly cuneate; apex acute or with to 1 cm long broad acumen; nerves 17-20 pairs, slender, hardly raised beneath, at 80° at the base, down to 45° towards the apex; secondary nerves densely scalariform, slender, obscure; midrib obscure and depressed above, slender but prominent and terete beneath; petiole 10-18 mm long, slender. Panicles to 11 cm long, slender, lax, terete or ribbed, terminal or more rarely axillary; doubly (if terminal) or singly branched; branchlets to 5 mm long, bearing to 6 flowers; bracteoles unknown. Flower buds to 10 by 5 mm, ellipsoid. Sepals lanceolate, the inner 2 somewhat shorter, more narrowly acute, than the outer 3. Petals white. Stamens 25(-30); filaments slender, tapering, c. 1.5 times length of the narrowly oblong anthers; appendages very slender, c. 3 times length of anther, villous towards apex. Ovary ovoid; style columnar, tapering, ± twice length of ovary, villous in the basal 1/2, prominently trifid at apex. Fruit pedicel to 3 mm long, to 2 mm ø; 3 longer fruit calyx lobes to 9.5 by 1.6 cm, lorate, obtuse, to 8 mm wide above the 8 by 8 mm suborbicular somewhat thickened saccate base; 2 shorter lobes to 5.5 by 0.4 cm, otherwise similar.
