Characteristics

Small to medium-sized tree. Young twigs, leaf buds, parts of petals exposed in bud, ovary, panicles, petioles, stipules outside (sparsely so within) and nervation above (glabrescent beneath) densely evenly shortly persistently pale ocherous pubescent; sepals thus at first, becoming sparse in fruit. Twig c. 2 mm ø apically, ribbed at first, becoming terete, chocolate-brown, minutely pale lenticellate. Buds to 3 by 2 mm, ellipsoid, subacute. Stipules to 8 by 5 mm, elliptic, obtuse, fugaceous. Leaves 4-18 by 1.5-6.5 cm, elliptic, chartaceous; base cuneate; apex acute or with to 1 cm long slender acumen; nerves 7-12 pairs, slender but prominent beneath, arched, at 35°-45°; tertiary nerves slender, scalariform; midrib applanate above, prominent beneath; petiole 8-10 mm long. Panicle to 10 cm long, ribbed; singly branched, branchlets short, bearing to 8 congested secund flowers; bracteoles unknown. Flower buds to 5 by 2 mm, lanceolate; sepals broadly ovate, subequal, the outer 3 acute, the inner 2 subacuminate; stamens c. 30; filaments compressed, tapering; anthers ellipsoid, glabrous; appendages hardly exceeding anthers, with to 5 long bristles; ovary ovoid, with short columnar style. Fruit pedicel to 2 mm long, slender; 3 longer calyx lobes to 8 by 1.5 cm, spatulate, obtuse, c. 4 mm wide above the to 5 by 5 mm saccate thickened base; 2 shorter lobes to 4.5 by 0.4 mm, linear, acute, otherwise similar.
