  Species Description - Tree; young shoots minutely appressed puberulous at first, soon glabrous, greyish-brown, lenticellate, becoming cracked and fissured. Leaves spaced or loosely clustered at the shoot apex, spirally arranged, 5.7-24 × 2.5-8.5 cm, usually elliptic, less frequently oblanceolate, apex narrowly attenuate, acute or rounded, base narrowly attenuate, decurrent on the petiole, chartaceous to thinly coriaceous, glabrous; venation usually eucamptodromous, less frequently brochidodromous, sometimes with a marginal vein, midrib slightly raised or flat on the upper surface, secondary veins (8-) 13-20 pairs, parallel, straight or slightly arcuate, raised on both surfaces; intersecondaries usually short or absent; tertiaries oblique to horizontal, joined by a finer reticulum. Petiole 0.4-1.5 cm long, not channelled, glabrous. Fascicles 2-10-flowered, axillary and in the axils of fallen leaves. Pedicel 1.5-6 mm long, sparsely appressed puberulous. Flowers bisexual. Sepals five, 1.5-3 mm long, lanceolate, ovate or elliptic, apex acute to rounded, sparsely appressed puberulous outside, glabrous inside, often ciliate. Corolla 2-3 mm long, tube 0.5-1 mm long, lobes five, 1.5-2 mm long, ovate, apex obtuse, often slightly auriculate at base, glabrous. Stamens five, fixed near the top of the corolla tube; filaments 0.5-1 mm long, not geniculate, glabrous; anthers 0.6-1 mm long, lanceolate or ovate, acute, glabrous. Staminodes usually absent, occasionally present as 1-5 small vestiges to 0.5 mm long. Ovary ovoid or conical, five-locular, densely pubescent, style 0.75-1 mm long after anthesis, pubescent in lower half; style-head simple. Fruit (1.5-)3.5-5 cm long, ovoid, subglobose or obovoid, apex acute to rounded or truncate, base rounded or truncate, usually drying black, thick walled and not contracting or shrivelling on drying, smooth or irregularly and coarsely tuberulate, glabrous. Seeds several, 1.4-2.5 cm long, laterally compressed, testa smooth, shining, 0.3-1 mm thick; scar adaxial, extending most of the length of the seed and sometimes along the base, 1.5-3 mm wide; embryo vertical, with foliaceous cotyledons and long exserted radicle, surrounded by copious endosperm.
