Male racemes up to 17 cm long; bracts 1 mm long, triangular-ovate, pubescent, 2–20-flowered, the flower clusters remote, occasionally the lowest pedunculate. Bisexual racemes resembling the male ones, but with the addition of 1–2 female flowers at the base, in the middle or at the top of the axis. Female racemes up to 20 cm long; bracts 2 mm long, narrowly lanceolate, sparingly pubescent, 1-flowered, the flowers remote.
Leaf blades 6–15 × 2–6 cm, elliptic-lanceolate, acutely acuminate, sharply glandular-serrate on the margin, attenuate or cuneate at the base, firmly membranous, 3-nerved from the base, sparingly pubescent at first, soon glabrescent, dark green and shiny above, paler and duller beneath, sometimes purplish-tinged; basal glands usually absent; lateral nerves in 4–6 pairs, ascending, looped.
Female flowers: pedicels up to 7 mm long; calyx lobes 3, 1 × 0.75 mm, triangular-lanceolate, slightly accrescent in fruit, acute, very sparingly pubescent; disk glands 3, 1 mm long, ligulate, pinkish-purple; ovary 1.5 mm in diameter, 3-lobed, the lobes opposite the calyx lobes, smooth, glabrous, purplish; styles 3, less than 1 mm long, ± free; stigmas papillose, pinkish.
Male flowers: pedicels up to 2 mm long; buds 1.5 mm in diameter, subglobose, apiculate, glabrous; calyx lobes 3, 1.5 × 1.5 mm, suborbicular-ovate, greenish-white; disk glands absent; stamens 20–30, filaments very short, anther cells 0.3 mm long.
Tall shrub or small tree, up to 5 m high. Leaves simple, broadly elliptic to narrowly elliptic, 40-140 x 20-55 mm, very dark green, upper surface harshly hairy and rough to the touch. Racemes axillary. Flowers green.
Seeds 3.5 × 2.5 mm, ovoid, shallowly and finely reticulate-rugulose, pinkish-brown, pale grey in the depressions.
Racemes unisexual or bisexual, with the flowers dioecious or monoecious, pedunculate.
Fruit 4 × 7–8 mm, roundly 3-lobed, ± smooth, glabrous, purplish; columella 3 mm long.
Young shoots, petioles and axes sparingly appressed-pubescent, soon glabrescent.
Stipules minute, subulate, glabrous, soon falling.
A shrub or small tree up to 5 m high.
Petioles up to 5 cm long.
