Small understorey evergreen tree or shrub up to 5 m high. Branches terete, stout, pale green with dark transverse scars of the caducous stipules. Leaves alternate, coriaceous, glaucous, paler below, elliptic, usually about 8-16 cm long and 4-8 cm broad, margin serrate to spinoso-dentate; petiole 1-2 cm, stout. Flowers very small, arranged in compound, terminal or axillary, elongated panicles which are shorter than the leaves, bearing small clusters of brown velvet buds, bracts deciduous, small; pedicels short. Sepals broadly ovate, 2-3 mm long, obtuse, finely ribbed fan-wise with a membranous margin, persistent. Petals erect, narrowly elliptic, about 5 mm long, yellow, deciduous. Stamens on very short filaments, fused at the base; apical connective-appendage ovate-acuminate, petaloid; thecal appendage small to minute. Ovary globose, glabrous, style erect, terete, exserted, stigma apical, minute. Capsule globose, obtusely 3-lobed, about 1-2 cm in diam., hard, brown, verrucose; seeds angled, about 6 mm long, yellowish.
Leaves petiolate; lamina (7.5) 12–22 x 3–8.5 cm., narrowly oblong-elliptic to obovate, acute or acuminate at the apex, cuneate to rounded at the base, coarsely spinose-serrate with spines 0.5–3 mm. long, coriaceous, bright-or bluish-green above, pale green below, glabrous or rarely pubescent along the main veins, with venation prominent on both surfaces; petiole 5–25 (30) mm. long, channelled above, glabrous or minutely pubescent; stipules c. 5–10 mm. long, subulate, glabrous (? or minutely pubescent), soon caducous.
Stamen-tube without free margin, glabrous; anthers on short filaments (? or almost sessile), ovoid, glabrous with an ovate, obtuse, decurrent connective-appendage, and one entire or emarginate thecal appendage.
