Characteristics

Large tree. Twig, leaf bud, petiole and midrib beneath densely dark fulvous scabrid tomentose; more shortly, sparsely so on nervation beneath, midrib above and stipule outside; stipule within evenly densely pale fulvous caducous pubescent. Twig c. 1 mm ø towards the apex, stout, prominently ribbed at first, becoming terete; stipule scars c. 2 mm long, horizontal, obscure. Bud to 1.3 mm long and Ø, ovoid, compressed. Stipule to 2.5 by 0.7 cm, lanceolate, subcaudate, caducous. Leaves 11-19 by 7-12 cm, broadly oblong to obovate, thickly coriaceous; base obtuse to cordate; apex obtuse, subretuse or shortly acuminate; nerves 14-18 pairs, obscurely depressed above, prominent beneath, at 110° at the base, 45° at the apex; tertiary nerves remotely scalariform, prominent beneath; petiole 2.5-4 cm long, stout. Panicle to 20 cm long, ribbed, densely shortly fulvous scabrid tomentose, lax, axillary; singly branched, branchlets to 6 cm long, bearing to 12 secund flowers; bracteoles to 8 by 5 mm, oblong-ovate, subacute, shortly evenly caducous pubescent. Flower bud to 7 by 3 mm, lanceolate. Sepals densely pubescent; 3 outer ovate, acute, 2 inner ovate, thinner at the fimbriate margins, narrower at base, than the outer 3. Petals pink outside, crimson within, elliptic-lanceolate, pubescent on parts exposed in bud. Stamens 15, the inner 5 slightly longer than the outer 10 and reaching the style apex at anthesis; filaments broad and compressed at base, tapering abruptly medially and filiform below the broadly ellipsoid anthers; appendage to connective slender, 2-3 times length of anther, glabrous. Ovary ovoid, densely pubescent, crowned by a somewhat longer stoutly columnar densely pubescent stylopodium and short glabrous style. Fruit pedicel to 3 mm long, to 3 mm ø, stout. Fruit calyx at first sparsely pubescent towards base, becoming entirely glabrous; 3 longer lobes to 14 by 2.5 cm, spatulate, obtuse, c. 8 mm broad above the to 1.3 by 1.4 cm broadly ovate saccate thickened base; 2 shorter lobes to 12 by 1.2 cm, lorate, obtuse, otherwise as in longer lobes. Nut to 3 by 1.8 cm, narrowly ovoid, densely shortly evenly pale cream-brown pubescent; stylopodium to 4 mm long, apiculate.
