Leaves opposite, simple, rarely trifoliolate; blade elliptic to ovate or obovate-elliptic, (1.6)3.3-7.5(10) x (0.7)1.3-4 (4.5) cm, base cuneate, obtuse, or truncate, apex acute or short acuminate, subcoriaceous or coriaceous, adaxially glabrous, abaxially glabrous or nearly so except pubescent on costa, sometimes punctuate below, secondary veins 3-10 pairs, margin revolute, minutely serrate-crenulate or rarely sinuate, with 8-22 teeth on each side; costa flat or raised above, prominent and often pubescent beneath, secondary and tertiary venation flat on both surfaces, tertiary veination open to dense; petiole (1)10-25 mm long, 0.7-1 mm wide, glabrous to usually tomentose-pubescent. Juvenile foliage from young plants and coppice shoots either simple or trifoliate, with stipules often persistent. Stipules soon caducous, narrowly ovate-elliptic to elliptic-ligulate, 1.8-5 x 0.5-2 mm, apex rounded, or sometimes diamond-shaped to broadly ovate and conduplicate, 1.3-3 x 0.8-2 mm, externally strigillose or glabrous.
Inflorescences terminal, 1 or 3-5 racemes arising from same node as subtending leaves, 2.5-8(12) x 2-5 cm, peduncles and rachis segments 0.8-2.5(6.5) cm long, almost glabrous or sparsely to densely hairy, densely-flowered; floral bracts to 1.6 mm long, narrowly ligulate to subcarinate, strigulose, caducous; flowers inserted singly, unisexual to bisexual; pedicels 0.8-3 mm long, puberulent or glabrous; calyx lobes 0.6-1 x 0.5-1.2 mm, externally glabrous or strigulose; petals white, oblong, 1-2 x 0.7-1.2 mm, obtuse; male flowers with stamens 8, twice as long as pistil, filaments 2-3 mm long, anthers suborbicular, 0.4-0.5 mm long, ovary 0.6-0.9 mm long, usually pubescent, style c. 0.2 mm long, curved inwards; female flowers with stamens subequal to pistil, filaments 0.4-0.5 mm long, ovary 1.1-1.5 mm long, glabrous, styles 0.6-1 mm long, suberect, the stigmas capitate, papillose; bisexual flowers with filaments 2.8-3.5 mm long, ovary 1.5-2.2 mm long, glabrous or sparsely strigillose, style 1.2-1.4 mm long, stigma capitate, papillose.
Infructescence often dense, similar in size to inflorescence, 2.5-12 cm long, young fruits green to bright red. Capsules 3-7 mm long, 1.5-2.5 mm wide at dehiscence, exocarp glabrous or glabrate, endocarp sometimes separating from exocarp in old fruits; style plus stigma 0.5-1 mm long; calyx lobes caducous, central column present.
Seeds brown, oblong to ovoid-ellipsoid, 0.6-1 x 0.25-0.4 mm, comose with a tuft of weakly developed hairs 0.3-0.5 mm long at each end.
