Much-branched glabrous evergreen tree or shrub (2–)4–20 m. tall; branches stiff, grooved or ± winged, flattened, ± 3–4-angled or rounded; bark grey-brown, smooth, yielding a milky juice or yellow latex when cut.. Leaves opposite or rarely in whorls of 3–4; blades very variable, lanceolate or oblanceolate to broadly ovate or obovate, (1.2–)4–20 cm. long, (0.9–)1.5–8 cm. wide, rarely exceeding 11 × 4.5 cm., acute to rounded at the apex but apiculate, cuneate to rounded at the base, mostly dark green above and yellowish or pale green beneath, mostly distinctly coriaceous, the margin often thickened; venation mostly prominent on both faces when dry, the surface often rugulose, with translucent and opaque canals usually visible; petiole 0.3–1.8 cm. long, with prominent ligule 2–4 mm. long.. Flowers dioecious, in terminal lax ± condensed 1–many-flowered cymose inflorescences; peduncle 0–4 cm. long; bracts scale-like, keeled; pedicels 0–2 mm. long.. Sepals 5, reddish, ± unequal, rounded to triangular-ovate, 1–2.5 mm. long and wide, glabrous.. Petals 5, cream to greenish white, sometimes tinged with pink, with yellowish linear glands radiating from the base, fleshy, round to broadly obovate, 4–9 mm. long, 3.5–7 mm. wide, glabrous.. Male flowers with 5 yellow spongy honeycombed fasciclodes uniting to form a star in the centre of the flower, alternating with 5 greenish cream staminal-bundles, the filaments joined for most of their length, each bundle 3.5 mm. long, 0.7 mm. wide, with 5–9 red, brown or mustard-coloured anthers.. Female flowers with small fasciclodes alternating with sterile staminal-bundles; ovary green or yellowish, 2–4-locular; stigma white, peltate, 5-lobed.. Fruit green turning yellow, reddish brown or orange, globose, ovoid or 2–4-lobed, l–3(–5) cm. in diameter, smooth and glabrous.. Seeds red, 1–4, ovoid, l–2.2(–4.5) cm. long, 0.7–2(–3) cm. wide and 0.6–1.4 cm. thick, often much compressed.
More
Leaves opposite (rarely in whorls of 3), ± coriaceous, petiolate; lamina (2) 4–11 × (1) 1·5–6 cm., very variable in size, shape and texture, lanceolate or oblanceolate to broadly ovate or obovate, acute to rounded-apiculate at the apex, cuneate to rounded at the base, dark bluish-or yellowish-green above, paler below, flat or ± bullate, with main lateral veins prominent on both sides, tertiary venation usually ± prominent above, margins sometimes incrassate, and with branched translucent glandular canals visible in the young leaves at least, and longitudinal opaque canals visible below; petiole 3–18 mm. long and grooved above, transversely wrinkled; ligule prominent.
A small branched tree. It grows to 20 m tall. The bark is dark grey and smooth. The leaves are simple and opposite or in rings. The leaf stalk is 18 mm long and has wings.

They are in groups in the axils of the leaves. The fruit are green and turn yellow or orange as they ripen. They are oval and 1-3 cm across.
