Characteristics

Medium-sized tree. Twig, panicle, leaf bud, stipule and petiole densely shortly buff pubescent; midrib on both surfaces and nerves beneath sparsely dotted with minute hair tufts. Twig c. 1.5 mm ø apically, terete, much branched, slender, smooth, becoming finely rugulose; stipule scars short, pale, horizontal. Bud 2-3 by 1-2 mm, ovoid, frequently slightly compressed. Stipule c. 1 by 3 mm, hastate, acute, fugaceous. Leaves 5.5-11 by 2.5-4 cm, narrowly ovate to oblong-lanceolate; base broadly cuneate; acumen to 1 cm long, narrow; nerves 10-12 pairs, dense, prominent, straight, at c. 35°-55°; midrib slightly depressed above; tertiary nerves densely scalariform, at 90° to the nerves; petiole c. 8 mm long. Panicle to 7 cm long, terminal or axillary, terete; singly branched, branchlets to 1.5 cm long, short, bearing to 9 secund flowers; bracteoles to 3 mm long, elliptic, subacute, shortly pubescent. Flower bud to 6 by 2 mm, narrowly lanceolate. Calyx shortly tomentose outside, glabrous within; lobes ovate, subacute; inner 2 somewhat smaller, relatively broader, thinner, than outer 3. Petals pink, cream at margin, linear, pubescent on both surfaces, strongly contorted in bud. Stamens 20-30; filaments broad at base, tapering abruptly and filiform distally, glabrous; anthers oblong, glabrous, tapering, the outer cells larger than the inner cells; appendage to connective short, glabrous but for a single (-2) apical bristle. Ovary broadly ovoid, pubescent; stylopodium narrowly cylindrical, shorter than the ovary, pubescent; style as long as stylopodium, tapering, glabrous. Fruit calyx shortly buff pubescent; 3 longer lobes to 5 by 1.2 cm, spatulate, chartaceous, obtuse, c. 2.5 mm broad above the c. 5 by 4 mm saccate thickened base; 2 shorter lobes to 35 by 4 mm, subequal, spatulate, similar at base. Nut to 10 by 7 mm, ovoid, densely shortly buff tomentose; style remnant c. 1.5 mm long.
