Characteristics

Medium-sized, occasionally large, tree. Twig and petiole persistently dotted with scattered pale fulvous brown long hair tufts; nervation beneath and stipule more shortly so; fully expanded leaf glabrescent. Twig 2.5-3.5 mm ø apically, stout, straight, little branched, terete; stipule scars to 2 mm long, to 1 mm wide, pale, cuneate. Bud to 10 by 7 mm, a loose group of bud-scales, compressed. Stipule to 17 by 7 mm, broadly hastate, subauriculate, subacute, subpersistent (more so in young trees and saplings). Leaves 12-22 by 4.5-9 cm, narrowly oblong, chartaceous; base obtuse; apex taperingabruptly; acumento 8 mm long, broad; nerves 24-28 slender close pairs, prominent beneath, curved towards the margin; tertiary nerves slender, scalariform, at c.90°; midrib depressed above;petiole 1.2-2 cm long, short, stout. Panicle to 8 cm long, axillary, rarely terminal, becoming ramiflorous, terete, ribbed on drying,lax, glabrous but for sparse fulvous tufts towards base; singly branched, the branches short, bearing to 5 distichous flowers; bracts to 8 by 1.5 mm, narrowly lanceolate, acute, puberulentoutside, glabrouswithin;bracteoles to 5 by 3 mm, ovate, obtuse. Flower bud to5 by 3 mm,elliptic, obtuse. Calyx shortly densely pubescent outside, glabrous within; lobes subequal, ovate, the outer 3 rather narrower and subacuminate. Petals dark red with a pale margin, narrowly ovate, obtuse, densely yellowish gold pubescent on parts exposed in bud. Stamens 15, of 3 lengths, the inner 5 much longer than the others and almost reaching the style apex; filaments thick, tapering gradually; anthers broadly oblong, slightly tapering; appendages to connective short, becoming reflexed. Ovary and stylopodium narrowly conical to pyriform, shortly pubescent; style somewhat shorter than ovary and stylopodium, broadly filiform, glabrous. Fruit calyx glabrous; 3 longer lobes to 17 by 2.5 cm, oblong, obtuse, thinly chartaceous, not tapering basally; base thickened and saccate at the centre, with 2 thin, to 1.5 cm broad, lateral auricles; 2 shorter lobes subequal, to 8 by 0.7 cm, linear, saccate but not auriculate. Nut to 2.5 by 1.3 cm, ellipsoid, pruinose, glabrous; style remnant c. 1.5 mm long, acute.
