A shrub or small tree. It grows to 5 m tall. The bark is grey and striped. The leaves are oval and 2.5-3 cm long by 1.8 cm wide. Young leaves are red. Mature leaves are dark green. The midrib is red and hairy. The male and female flowers are separate on separate plants. Male flowers are very small and pinkish. They are in catkin like spikes about 10 mm long. The female flowers are green and single. They are like a small fruit and 6-7 mm long. They have a pair of long red styles.
Leaf blades 1–5.5 × 0.5–4 cm, elliptic-ovate or elliptic-lanceolate, subacute, obtuse or rounded, occasionally slightly acuminate at the apex, rounded or cuneate at the base, firmly chartaceous, pubescent along the midrib but otherwise ± glabrous above and beneath except for the tufts of domatial hairs beneath, sparingly gland-dotted beneath, bright or dark green above, paler beneath; lateral nerves inconspicuous, in 4–5(6) pairs.
Fruits 1.2–2.3 × 1–2.3 cm, suborbicular to obcordate, completely or almost completely surrounded by the wing, flat, borne on a stipe 1–3 mm long, emarginate at the apex, with the wing-tips sometimes overlapping, rounded or slightly decurrent on to the stipe at the base, glabrous, membranous, brown, red, yellow, whitish or greenish.
Female flowers: pedicels 1.5–3 mm long, extending to 7 mm in fruit, very slender; sepals 5–6, 3–4 mm long, linear, pubescent towards the apex; ovary 1 mm long, obovoid to oblong-ellipsoid, glabrous, with a few scattered gland-dots; styles 2–5(10) mm long, extending to 1.5 cm fruit, slender, divergent, red, caducous.
Shrub or small tree, up to 6 m high. Male flowers in spikes barely 10 mm long. Fruit with rose-coloured wing extending all around fruit except for narrow apical notch. Flowers pink or green.
Male flowers: buds reddish, orange or pink; calyx c. 1 mm across, shallowly 5-lobed, the lobes ciliate, whitish; anthers 0.8 mm long, yellowish; pistillode 2-lobed, 1 mm high.
Male inflorescences usually on short lateral shoots, laxly spicate or subpaniculate, 1–1.5(3) cm long, the axis slender; bracts 1 mm long, spathulate.
Female inflorescences terminal on short lateral shoots, 1.5 mm long, few-flowered, leafy at the base; bracts 2 mm long, lanceolate.
A tree up to 20 m high with a spreading crown, or a shrub branched from the base, sometimes scandent.
Seeds 7–9 × 2–4 mm, semicircular-oblong, smooth, purplish-brown or blackish.
Young shoots and petioles puberulous or pubescent, older twigs glabrescent.
Stipules 3–5 mm long, linear-lanceolate, pubescent, soon falling.
Bark smooth or longitudinally furrowed, tough, grey or brownish.
Petioles 2–8 mm long.
