Shrub or small tree up to 10 m. in height, with smooth or flaking yellowish grey bark; twigs densely, evenly or sparingly pubescent or almost glabrous, gland-dotted.. Leaf-blades oblong, oblanceolate-oblong or obovate-oblong, rarely ± ovate, (3–)5–7(–9) cm. long, 1.5–4 cm. wide, obtuse or rarely subacute, rounded or cuneate, entire, nerves 7–12 pairs, sparingly puberulous or glabrous above, sparingly or evenly puberulous beneath, or glabrous except for the midrib and angles between the midrib and main nerves, where there may be dense tufts of hairs in the domatia, densely gland-dotted beneath, ± coriaceous when mature; petioles 3–10 mm. long, evenly or densely pubescent.. Stipules linear-lanceolate to linear-filiform, 2–3 mm. long, minutely puberulous, soon caducous.. Male inflorescences 3–7 cm. long, spicate, the spikes often fascicled on older wood, with the flowers densely packed spirally on the axis; axis densely pubescent; bracts spathulate, 1 mm. long, ciliate-fringed.. Male flowers: calyx 1 mm. long, lobes 5, short, acute, ciliate, dark red; stamens 5, anthers 1.5 mm. long, thecae pubescent near the top, whitish, with the apical gland gold-coloured and prominent; pistillode cylindric, 1 mm. long, bifid and pubescent at apex.. Female inflorescences 2–3 cm. long, 5–6-flowered, leafy at the base, terminal on lateral shoots, axis pubescent, gland-dotted; bracts elliptic-oblanceolate, 1.5 mm. long, readily caducous, or flowers axillary, solitary.. Female flowers: pedicels 1 mm. long, sparsely pubescent, extending to 1(–2) cm. in fruit; sepals 5–8, linear, 2.5–3 mm. long, free, pubescent, gland-dotted, pinkish; ovary obovate-oblong to obcordate, compressed, 2-winged, 3 mm. long, glabrous or pubescent, with or without a few scattered gland-dots, crimson; styles filiform, 3 mm. long at first, later extending to 1.2 cm., rugose-papillose, purplish crimson.. Fruits V-shaped, compressed, with 2 divergent rounded-rhomboid wings at the apex, 2–2.5 cm. long (base to style-base), 2.5–4.5 cm. across the wings, on a stipe 2 mm. long, rounded or cordate at the base, reticulate, glabrous or pubescent, sparingly gland-dotted or not, the wings firmly membranous, longitudinally striate; axis fusiform, remaining after dehiscence.. Seeds ± semicircular, compressed, 1 cm. long, 0.5 cm. wide, smooth, shiny, dark purplish brown streaked with black.

Leaf blades 2.5–9.5 × 1.5–5 cm, elliptic-ovate to oblong-oblanceolate, rounded, obtuse or rarely subacute at the apex, rounded or sometimes cuneate at the base, thinly coriaceous at maturity, dark green above, paler beneath; upper surface sparingly or evenly pubescent to subglabrous; lower surface densely subferruginous-or fulvous-tomentose, or subglabrous except along the midrib and main nerves and the domatial hair tufts, sparingly to evenly gland-dotted; lateral nerves in 5–8(10) pairs, fairly prominent and camptodromous on leaf lower surface, scarcely prominent on upper surface and brochidodromous.
A shrub or small tree. It grows up to 6 m high. The bark is light brown, smooth and flaky. Young branches are rust coloured. Leaves are oblong. They are 2.5-9 cm long by 2-4 cm wide. They have brown velvety hairs. The flowers are separate sexes on separate trees. Male flowers are reddish in spikes up to 6 cm long. Female flowers are green. Each one looks like a small fruit with 2 long red forked styles. They can be single or in clusters. The fruit is a flattened capsule with 2 wings. These give the shape of a heart. These become red when mature.
Female flowers: pedicels 1 mm long, extending to up to 2 cm long in fruit; sepals 5–9, 1.5–4 mm long, free or sometimes partially united, linear, usually readily caducous, pinkish; ovary 2 × 1 mm, obovoid-oblong to obcordate, 2-winged in the upper half, gland-dotted, glabrous or densely pubescent, glaucous or crimson; styles 2(3), 0.2–2 cm long, the arms 0.25–1 mm thick, filiform, rugose-papillose, reddish-purple.
Fruits borne on a stipe 2 mm long, flat, 2–3.5 × 2.3–4 cm, V-shaped, with 2 apical divergent rounded-rhomboid membranous striate wings, rounded or cordate at the base, reticulate, glabrous or pubescent, gland-dotted or not, somewhat shiny, yellow-green at first, turning pink then reddish-brown, dehiscent into 2 subtrapeziform cocci leaving a compressed-fusiform columella.
A shrub or small tree up to 10 m high, often straggling or untidy; crown flat or rounded; upper branches spreading, lower branches drooping; bole 15–30 cm in diameter at breast height, often stunted or contorted; bark smooth, light brown or grey, flaking off to leave a powdery rufous or fulvous underbark.
Male flowers: buds open, deep reddish-carmine or brownish; calyx 1.5–2 mm across, shallowly 5-lobed, the lobes obtuse, ciliate, pinkish; anthers 1.2 mm long, dorsally purplish-tinged, pollen pale yellow; pistillode 2-lobed, 1 mm high.
Male inflorescences 2–7 cm long, densely spicate, amentiform, the spikes solitary or fasciculate in the axils of fallen leaves; axis pubescent; bracts 1 mm long, spathulate, ciliate.
Female flowers axillary or solitary, or in few-flowered racemes up to 3 cm long terminating lateral leafy shoots; axis and bracts ± as in the male.
Seeds 1 × 0.5 cm, compressed-semicircular, smooth, shiny, dark purplish-brown streaked with black.
Stipules 1–3 mm long, linear-lanceolate to filiform, pubescent, soon falling.
Young shoots and petioles pubescent or puberulous, glabrescent.
Branchlets becoming rusty-powdery when the bark peels off.
