Characteristics

Medium-sized or large tree. Young twig, panicle, leaf bud, stipule (both surfaces), and petiole shortly evenly densely deep rufous-brown puberulent, becoming pale mauve-grey, sparsely so on nervation beneath and midrib above. Twig 3-6 by 1-2.5 mm ø apically, compressed, becoming smooth, glabrous; stipule scars to 2 mm long, shortly cuneate or falcate, ± ascending, sometimes horizontal, prominent. Bud 7-11 by 3.5-4.5 mm, hastate, compressed, acute. Stipule to 14 by 5 mm, small, oblong, obtuse, fugaceous. Leaves 11-20 by 5.5-7 cm, elliptic to ovate; coriaceous, gold lepidote beneath, becoming mauve-grey in mature trees; base obtuse or broadly cuneate; acumen to 8 mm long, broad; nerves 11-14 pairs, curved, not strongly raised beneath, at 50°-60°, to 90° at base; tertiary nerves remotely scalariform, slightly diagonal to nerves; midrib prominent beneath, +-depressed above; petiole 2-4 cm long. Panicle to 20 cm long, terminal or axillary, lax, +-compressed; singly branched, branchlets to 2.5 cm long, short, bearing to 8 distichous flowers; bracts to 15 by 9 mm, oblong, obtuse, shortly pubescent outside, puberulent within, fugaceous; bracteoles to 13 by 8 mm, otherwise as with bracts, caducous. Flower bud to 9 by 3 mm, lanceolate, obtuse. Calyx outside shortly pubescent or glabrescent, glabrous within; lobes subequal, deltoid, the inner 2 slightly shorter, thinner, somewhat expanded at base. Petals pink, paler along margins, lanceolate, obtuse, sparsely pubescent on parts exposed in bud. Stamens 15, the inner 5 slightly longer; filaments broad, tapering in the distal half, united in a ring at the base; anthers oblong; appendage to connective 2-3 x length of anther, reaching almost to style apex. Ovary ovoid, frequently sparsely pubescent apically; style and stylopodium cylindrical, 1.5-2 x length of ovary, rather short, glabrous. Fruit base frequently impressed. Calyx glabrescent, sparsely dotted with minute hair tufts; 3 longer lobes to 19 by 2.7 cm, spatulate, obtuse, to 1.2 cm broad above the to 1.2 by 1.8 cm broadly ovate deeply saccate thickened base; 2 shorter lobes to 10.5 by 0.9 cm, subequal, linear, similar at base. Nut to 4 by 2.8 cm, broadly ovoid, shortly persistently evenly pale buff tomentose; style remnant to 4 mm long, conical.
