Leaf-blades ovate, elliptic or elliptic-oblong to ovate-lanceolate or oblong-oblanceolate, 2.3-13.5 cm. long, 1.1-7.5 cm. wide, rounded, subacute or very shortly acuminate at the apex, ± rounded to cuneate at the base, 3-nerved from just above or a short distance from the base for at least half the length and often a weaker nerve on each side from the top of the petiole, the other venation pinnate, glabrous, sometimes ± glaucous beneath, slightly revolute; petiole red, 0.5-1 cm. long.. Flowers yellowish green, ± 7-9 in inflorescences 1-3 cm. long; peduncle 0.8-2.5 cm. long, ultimate axes 3 mm. long, true pedicels ± absent.. Perianth ± 3 mm. long, the tube up to 2 mm. long; inner lobes slightly narrower than the outer, ± 2 mm. long, finely pubescent.. Filaments pubescent, the outer 6 anthers ovate, ± 0.75 mm. long, acuminate; inner smaller, narrowly acute; glands stipitate, 1.3 mm. long, inserted between second and third whorls, colliculate; staminodes substipitate.. Fruits black, subglobose, 1.6-2 cm. long, 1.3-1.5 cm. wide, ± narrowed at base, ± acuminate at apex, crowned with the short persistent cylindric perianth-tube neck.. Fig. 2.

Leaves leathery; petiole 5–12 mm long, slightly channelled above, glabrous; lamina (3)4–10(11) x (1.7)2–4.5(6.5) cm, broadly ovate or ovate-elliptic, obtuse to rounded and ± emarginate at the apex, rarely obtusely and shortly acuminate, broadly cuneate at the base, ± undulate on the margin; at first rusty-tomentellous, particularly on the nerves, soon glabrescent on both surfaces, except sometimes along the midrib and the nerves beneath; lateral nerves in 4–5 pairs, the lowest nerves opposite or sub-opposite arising above the leaf base, obliquely to the midrib and remote from the next nerves, reticulation obscure; upper surface glossy dark green, with midrib slightly impressed; lower surface greenish or cinnamon-brown, becoming bluish-green with prominent midrib and nerves, reticulation very dense, obscure.
Fertile stamens 9 in 3 whorls, with a fourth (innermost) whorl of staminodes; filaments of outer whorl tomentellous, shorter than the tepals, anthers c. 1 mm long, acute at the apex; filaments of inner whorls similar but shorter, glands c. 0.5 mm in diameter, globose with a pilose stalk; staminodes c. 1 mm long with short pilose filaments and ovate-lanceolate acute glabrous antherodes.
Flowers white to cream-coloured, small, cinnamon-tomentellous; pedicels up to 1 mm long; receptacle 1–1.5 mm long, cylindric-urceolate, constricted near the apex, tomentellous outside and inside; tepals erect-patent, 2–2.5 mm long, elliptic, acute and incurved at apex, tomentellous outside and inside.
Medium to large evergreen tree (8)10–35(50) m high, sometimes flowering as a shrub c. 5 m high; stem buttressed; crown ± rounded; bark brown to grey-brown, smooth with shallow longitudinal fissures and flaking in small patches; slash brown, fine-grained.
Fruit 1.3–1.8 cm in diameter, globose or nearly so, black and somewhat fleshy outside; mature ovary enveloped by the accrescent receptacle; fruiting pedicel thick, 2–4 mm long.
Cymes paniculately arranged, few-flowered, axillary; rhachis 1.5–5 cm long, usually fulvo-tomentellous; peduncle 0.5–2.5 cm long; bracts lanceolate, minute, caducous.
Young branches and apical buds densely rusty-tomentellous, soon glabrescent, older twigs with smooth or longitudinally lenticellate grey bark.
Ovary up to 1 mm long, ovoid, glabrous; style short, stigma capitate.
