Shrub or tree 1.5-7(-20) m high. Branches sparsely lenticellate; branchlets glabrous. Leaves in whorls of 3 or 4; petiole 0.5-1.5 cm long, glabrous; blade subcoriaceous, elliptic, 5.5-12.5(-21.5) by 1-3.6 cm, 3-9.7 times as long as wide, apex acute, rarely acuminate, base cuneate to slightly decurrent, glabrous above and beneath; secondary veins (14-)21-27(-31) pairs, 0.1-0.3(-0.6) mm spaced, more or less straight, 45-65° from midrib. Inflorescence 3-9.5 cm long, in whorls of 2-4(-6), congested, 32-more than 35-flowered; peduncle 2.3-5 cm long, glabrous; pedicels 1-2.5(-5) mm long, glabrous. Sepals broadly ovate, 1.1-1.3 by 0.9-1.4 mm, 0.9-1.3 times as long as wide, apex obtuse to rounded. Corolla glabrous outside, villose from just around the mouth downwards for 1-1.2 mm, 3 mm long in the mature bud, and forming a subglobose head of 1 by 1.5 mm, usually indistinct from the tube; tube cylindrical, 2-2.4 mm long, 1.6-1.9 times as long as calyx, 1.4-1.8 times as long as lobes; lobes broadly and obliquely ovate, 1.1-1.5 by 1.2-1.5 mm, 0.9-1.1 times as long as wide, apex rounded, sometimes slightly retuse. Stamens inserted at 1.9-2.1 mm from base, c. 0.9 of the length of the corolla tube; filaments 0.5 mm long; anthers 1-1.1 by 0.2-0.3 mm, 3.3-5 times as long as wide. Disk cup-shaped, 0.7-1 mm high, 0.7-0.8 times as long as ovary, serrate. Gynoecium mostly glabrous; ovary syncarpous, c. 1 mm long; style 1-1.3 mm long; style head 0.6-0.8 mm long, puberulous. Fruit bluish black when mature, syncarpous or partly so, broadly ovoid, subglobose or trapezoid, often cleft at the apex, 7-9.2 by 7-10.2 mm, 0.8-1.1 times as long as wide, connate for 0.6-0.9 of fruit length when cleft, distance between apices 2-7.5 mm, apices acute, base thickened, sometimes only 1 carpel developing, glabrous. Seeds 3-5.5 by 2-2.7 mm.
Lowland rain forest and in secondary thickets. Open areas, scrub, thickets, secondary forests, sometimes also along the edge of coconut plantations, at elevations up to 500 metres, occasionally to 750 metres.
