Tree (2.5-)5-20(-27) m high. Branches rather densely lenticellate; branchlets glabrous. Leaves in whorls of 3 or 4; petiole 0.6-5 cm long, glabrous; blade coriaceous, elliptic to obovate, 7-28 by 2-9.3 cm, 1.5-4.8(-6) times as long as wide, apex acuminate to rounded or emarginate, base cuneate to decurrent, glabrous above and beneath; secondary veins 9-32 pairs, 0.15-1(-1.5) cm spaced, straight or slightly arcuate-ascending, forming an angle of 45-90° with the midrib, forming a submarginal vein. Inflorescence (2.5-)5-21.5(-27) cm long, in whorls of 3-5(-6), 26-more than 35-flowered; peduncle 1.8-14 by 0.2-0.25 cm; pedicels 0.1-1.2 cm long, glabrous. Sepals 1-2 by 1.4-2 mm, 0.5-1.3 times as long as wide, apex obtuse to rounded, rarely acute, glabrous. Corolla white, glabrous outside, villose in a belt of 1.5-2 mm wide just at the mouth, and gradually turning sparsely so downwards, 3.5-5 mm long in the mature bud and forming a broadly ovoid to subglobose head of 1-2.2 by 1.3-2 mm, usually indistinct from the tube; tube 3.4-4.9 mm long, 2.4-3.4 times as long as calyx, 1.95-3.3 times as long as lobes; lobes obliquely and broadly ovate or suborbicular, 1.3-2.1 by 1.3-2.1 mm, 0.7-1 times as long as wide, rounded, rarely retuse. Stamens inserted at 2.5-4.5 mm from base, 0.7-0.9 of the length of the corolla tube; filaments 0.5-0.8 mm long; anthers 0.9-1.5 by 0.25-0.7 mm, 1.6-4 times as long as wide. Disk cup-shaped, 1-1.8 by 0.7-1.4 mm, or 0.6-0.9 times as long as ovary, crenate. Pistil glabrous; ovary ovoid, syncarpous, 1-1.75 mm long; style 1.2-2.5 mm long; style head 0.6-1 mm long. Fruit bluish black or purplish black when mature, syncarpous, variable in shape, globose, rounded, sometimes truncate, retuse or slightly cleft at apex, rarely ovoid or ellipsoid, 6.5-21 by 7-18 mm, 0.9-1.8 times as long as wide, connate for 6-11.7 mm, 0.9-1 of its length, distance between apices 2-3 mm, glabrous. Seeds 1 in each endocarp, ovoid, acute, 3-9(-12) by 1-3.2 mm, 2.2-4 times as long as wide, glabrous.
