Flowers fragrant; sepals ovate, 0.5–1.3 mm long, 0.3–1.5 mm wide, obtuse at the apex, glabrous, sometimes slightly ciliate; corolla hypocrateriform, (greenish) white; tube broadly cylindrical, 3.2–5.5 mm long, densely setose in the mouth and at base of lobes; lobes ovate or obovate, 0.6–1.6 mm long, 0.8–1.6 mm wide; stamens inserted 1.9–4.2 mm above the corolla base; disk 0.2–0.7 mm high, annular or cupular; pistil 1.2–3.8 mm long; ovary of 2 free or partly fused carpels, globose to obovoid, glabrous; style 0.6–3.2 mm longr.
Inflorescence congested, on ultimate branches only, up to 450-flowered; peduncle 5.8–13.5 cm long, glabrous; pedicels 0.1–2 mm long, glabrous.
Fruit dark red or black, often lenticellate, syncarpous when both carpels develop, obcordate, bilobed, 10–30 mm long, 7–23 mm in diameter; when only one carpel developes, subglobose to ellipsoid and 5–20 mm in diameter; seeds 7–13 mm long.
Tree 7-16 m high and up to 1.5 m in diameter, with all parts glabrous; bark smooth; sap watery, bitter. Leaves in whorls of 3-5, often unequal, lanceolate, long oblong or oblanceolate, acute to acuminate, long cuneate at the base, 12-28 cm long and 2.5-6 cm broad, dark green and shiny above, paler below, thinly coriaceous; secondary nerves 20-30 on each side, spreading at a wide angle; petiole 1-3.5 cm long; axillary glands forming a dense fringe. Stipules 0. Inflorescence much branched with dense cymes at the ends of secondary or tertiary branchlets of large umbels: peduncle 2-6 cm long; bracts minute. Flowers white, small, waxy; pedicels 1 mm long. Calyx cup-shaped, 1 mm long, 5-toothed or lobed. Corolla salver-shaped: tube cylindric to subcampanulate, thickened towards the apex, 3-4.5 mm long, mouth densely filled with whitish hairs; lobes ovate, 1 mm long. Stamens 5, inserted above the middle; anthers ovate, cordate, 0.5-1 mm long; filaments very short, terete. Disc cup-shaped, sinuate. Ovary of 2 carpels, connate in flowering stage, more or less fused in fruit or often only one developing; style terete, 1.5-2 mm long; stigma papillose, capitate, consisting of a thickened annular ring with a basal ±9 rim and a short, truncate, bilobed apex; ovules 51 mm each cell, collateral.
