Information
A shrub c. 2 m high, or tree to 7 m, dioecious or monoecious.Twigs greyish-brown, lenticellate.Young growth densely fulvous-lepidote.Stipules 3–10 mm long, subulate.Petioles 0.5–6 cm long.Leaf blades 2–15 × 2–10 cm, ovate, acutely shortly acuminate at the apex, sometimes obtuse or emarginate through deformity, entire or subentire on the margin, rounded to shallowly cordate at the base with a pair of sessile discoid basal glands beneath, chartaceous, sparingly scurfily stellate-pubescent and green on the upper surface, silvery-lepidote beneath; 5–9-nerved from the base, lateral nerves in 5–8 pairs, ± impressed above, prominent beneath.Racemes 2–10 cm long, terminal, mostly female with a short apical male portion, or all female; bracts minute.Male flowers: pedicels 3 mm long; sepals 5, 2 × 1 mm, triangular-ovate, yellowish-lepidote without, glabrous within; petals 5, 2 × 0.5 mm, oblong-oblanceolate, pubescent, ciliate, pale yellowish-cream in colour; disk glands 5, rounded or truncate; stamens 17–20, filaments 2–3 mm long, sparingly pubescent, anthers 1 mm long; receptacle pilose.Female flowers: pedicels 3 mm long, stouter than in the male, densely lepidote; sepals 5, 3–4 × 1.5 mm, triangular-lanceolate, subacute, lepidote without, pubescent within, greenish; petals absent; disk shallowly 5-lobed, the lobes rounded; ovary 2 mm in diameter, subglobose, densely fulvous stellate-lepidote; styles 3, 2–3 mm long, erect or spreading, twice bipartite with linear-filiform segments, sparingly stellate-pubescent abaxially, purplish. Fruits 5 × 6–7 mm, trilobate-subglobose, septicidal, evenly stellate-lepidote.Seeds 3.5–4 × 2.5–3.5 × 2–2.5 mm, ovoid, smooth, somewhat shiny, dark brown; caruncle c. 1 mm wide, ± flattened.
