Tree or rarely shrubby, (3-)10-35 m high, buttresses absent. Twigs glabrous or with very short hairs. Leaves with petiole 0.2-1.7(-2) cm and blade usually coriaceous, 1.7-11.5(-16.5) by 1-7(-8.5) cm, elliptic, oblong, ovate or obovate, with the base cuneate to truncate, rounded or rarely ± cordate and the apex usually rounded or obtuse, sometimes emarginate, rarely acute; glabrous; glands rare; margin crenulate; secondary veins in 9-15 pairs, usually straight and unbranched almost to margin, often ± perpendicular to midrib towards base of blade, subparallel, often closely spaced especially towards base, 2-3 mm apart in small to medium leaves, up to 7 mm apart in larger leaves. Stipules lingulate or narrowly triangular, 4-12 by 1-2.5 mm, glabrous. Inflorescence terminal, well-developed to compact, paniculate to corymbose; median axis 2.5-14 cm long by 2-3(-5) mm diameter, (4-5 mm diameter in fruiting stage), bearing 3-6 pairs of major lateral branches; axes sparsely to densely pubescent. Flowers usually bisexual, (4.5-)6-7 mm diameter; 5-6-merous (except for gynoecium); almost sessile to shortly pedicellate, pedicel below articulation 0.5-2 mm, above 1-2 mm; hypanthium sparsely pubescent; calyx lobes 2.5-3.5 by (1.2-)1.5-2.5 mm, ± glabrous on outer surface; petals (1-) 2-4 mm long, basal part 1-2.5 plus teeth 0.5-2 mm; filaments (2-)2.5-3 mm long; disc lobes fleshy, sometimes paired, 0.5-1 mm diameter; ovary 2-3-carpellate, globose to ovate, 1-2 mm diameter, glabrous; styles 1.5-3 mm; ovules c. 10 per ovary.
