Characteristics

A much-branched shrub 1–5 m. tall or tree up to 25 m. tall.. Young shoots glabrous, puberulous or evenly to densely fulvous-pubescent, later becoming glabrescent.. Twigs greyish or brownish, lenticellate.. Branches usually pendulous.. Bark grey or brown, lightly streaked, soft, thick, later flaking in long irregular strips.. Petioles 1–5(–9) mm.  long, terete, grooved or winged, glabrous or evenly to densely crisped-puberulous; leaf-blade elliptic-lanceolate, elliptic-ovate, obovate-oblanceolate, obovate or suborbicular-obovate, (1–)2–8(–17) cm. long, (0.5–)1–4(–9.5) cm. wide, acutely acuminate, acute, subacute, obtuse or rounded at apex, cuneate, rounded-cuneate or rounded at base, thinly chartaceous, lateral nerves 6–10(–14) pairs, scarcely prominent above, somewhat so beneath, glabrous above and beneath, or else with the midrib puberulous beneath and otherwise glabrous, or sparingly puberulous with the midrib evenly pubescent beneath.. Stipules linear-lanceolate or oblong, 2–5(–10) mm. long, acute or obtuse, entire, membranous, glabrous or almost so, readily deciduous.. Inflorescence-bracts perulate, ovate, 2–3 mm. long, drying blackish, soon caducous.. Male flowers: pedicels up to 1 cm. long, glabrous or sparingly puberulous; sepals somewhat unequal, obovate-oblong, adaxially concave, (1–)2.5(–3) mm. long, glabrous or somewhat puberulous without, becoming reflexed; disc shallowly 4-lobed; stamens 3–4 mm. long; anthers (0.4–)0.8(–1.4) mm. long.. Female flowers: pedicels (0.15–)0.4–1(–1.8) cm. long, thickening distally, glabrous to evenly puberulous, extending or not in fruit; sepals ovate to suborbicular-ovate, 3 mm. long, glabrous or slightly puberulous without at the base; disc ± entire; ovary 2 mm. diameter, glabrous or sparingly to evenly puberulous; styles ± free and erect or suberect or else united for ± 1/2 their length into a perpendicular column (0.2–)1–2 mm. high, the free portions spreading or reflexed, 2(–3)-fid.. Fruits subglobose or shallowly to very deeply (2–)3–4-lobed, 5–7 mm. long, 1–1.3 cm. wide, smooth or irregularly warty, often with a prominent reticulate nerve-network, glabrous or sparingly puberulous, golden-brown when mature.. Seeds closely approximate, (2.5–)4–5 mm. long, (2–)3–4 mm. wide, ± smooth, metallic blue.. Fig. 6.
More
Perennial tree or shrub, 1-30 m high; many-stemmed, densely branched; flattened crown; twigs lenticellate. Leaves chartaceous, obovate to elliptic-lanceolate, base rounded to cuneate, apex obtuse or rounded to acutely acuminate; glabrous above and beneath; petioles terete, grooved or winged. Stipules linear-lanceolate or oblong, acute or obtuse, entire, membranous, soon falling. Inflorescence: bracts ovate, chaffy, soon falling. Male flowers: pedicels glabrous or sparingly pubescent; sepals unequal, concave, becoming reflexed; disc shallowly 4-lobed; stamens 2-3 mm long. Female flowers: pedicels 2-20 mm long; sepals entire, thick; ovary glabrous or sparingly to evenly puberulous; styles erect, spreading or reflexed. Fruit subglobose to shallowly or deeply (2)3(4)-lobed, smooth or verrucose. Seeds: exotesta fleshy; endotesta planoconvex, smooth.
It can be a shrub but also a large tree. It can be 8 m high or 20 m high. The bark is pale grey and smooth. In large trees with buttresses the bark can be rough. The leaves are oval and 2-8 cm long by 1.3-4 cm wide. They can be larger in large trees. The leaves are bright green. The edges roll under. The flowers are small and greenish-yellow. The sexes are on different trees. Male flowers are many and in the axils of leaves. Female flowers occur in pairs in the axils of leaves. The fruit is a 3 lobed capsule. It is yellow and 10 mm across. They turn blue when ripe. There are 6-8 seeds per fruit. There are several varieties.
Leaf blades 1–11 × 0.5–6 cm, obovate to elliptic-lanceolate, obtuse or rounded to acutely acuminate, rounded to cuneate at the base, chartaceous, glabrous above and beneath or else puberulous at least along the midrib beneath; pale green and dull or dark green and shiny (var. nitida) above, paler beneath; lateral nerves in 5–15 pairs, sometimes with 1–2 interstitials between each pair, scarcely prominent above, somewhat so beneath, tertiary nerves reticulate.
Female flowers: pedicels 2–20 mm long, not or only slightly extending in fruit; sepals ± as in the male flowers, greenish; disk 1.5 mm in diameter, ± entire, thick; ovary 2 mm in diameter, glabrous or sparingly to evenly puberulous; styles 2–4 mm long, stylar column 0–2 mm high, stylar arms 2 mm long, erect, spreading or reflexed.
Semi-deciduous shrub or small tree with spreading crown. Trunk straight, buttressed. Bark brown, rough, flaking irregularly to expose red-brown under bark. Leaves simple, ovate to obovate; bright green, papery. Flowers inconspicuous, yellowish-green. Fruit a three-lobed capsule, yellow.
Male flowers: pedicels 2–7 mm long, glabrous or sparingly pubescent; sepals 1–3 × 1–1.5 mm, unequal, concave, becoming reflexed, pale yellow-green; disk 0.5–2 mm in diameter, shallowly 4-lobed; stamens 2–3 mm long, anthers 0.5–1.5 mm long.
Fruits 5–7 mm long, 1–1.3 cm wide, subglobose to shallowly or deeply (2)3(4)-lobed, smooth or verrucose, often prominently nervose-reticulate, glabrous to sparingly puberulous, golden-brown when ripe.
Seeds 5 × 5 × 2.5 mm; exotesta fleshy and bright glossy metallic-blue or purplish-blue when fresh, drying papery and greyish-white; endotesta plano-convex, smooth.
A many-stemmed, densely branched spreading to somewhat sarmentose deciduous shrub or tree up to 25 m high (rarely more) often with a flattened crown.
Stipules 2–13 mm long, linear-lanceolate or oblong, acute or obtuse, entire, membranous, soon falling.
Petioles 1–9 mm long, terete, grooved or winged, glabrous to densely crisped-puberulous.
