Leaves usually clustered near the apices of the branches, sometimes immature at time of flowering, paired, glabrous; blades 10–20 × 3–7 cm, narrowly elongate-oblong, narrowly elliptic, or elliptic, obtuse or acute at the apex, acute to attenuate at the base; midrib straw-coloured, prominent beneath; lateral nerves in 15–18 main pairs; domatia absent; bacterial nodules dot-like or less often elliptic or linear, usually many; petiole well developed 1.5–4 cm long; stipule limbs truncate, 3–6 mm long, shortly acuminate, glabrous outside.
A shrub or small tree. It grows 5 m tall. The main stem usually branches low down. The bark is dark grey and rough and cracked. The leaves are opposite and often in clusters near the ends of branches. They are narrowly oval and 25 cm long by 8 cm wide. They are leathery and shiny green. There are nodules scattered over the leaf. The flowers are white and in large clusters in the axils of leaves. The fruit are in branched clusters and 5-7 mm across. The are round and black.
Inflorescences corymbose, crowded or moderately lax, 4–9 cm across (excluding corollas); peduncles 0–5(10) mm long; primary inflorescence branches 0.8–2 cm long, glabrous; second-to fourth-order branches present; pedicels 0.8–8 mm long, glabrous; bracts 4–8 mm long, usually slightly corky, caducous; bracteoles ± membranous.
Tree, up to 4.5 m high. Leaves large, elliptic to narrowly elliptic to lanceolate, glabrous, petiojate, bacterial nodules dot-shaped and scattered. Calyx cup-shaped or with 4 small teeth. Corolla tube 10-15 mm long. Flowers white.
Small tree 2–5 m tall; young branches glabrous; older branches stout, covered with thin mid to dark grey cracking bark and sheathed by persistent stipules.
Corolla tube 0.9–1.3 cm long, 1.5 mm wide at the top, glabrous outside, with few hairs within; lobes 7–8 × 2–2.5 mm, oblong, shortly apiculate.
Calyx glabrous; tube 1–1.5 mm long; limb-tube 1–1.75 mm long, ± twice as broad as the tube, truncate or undulate to slightly dentate.
Inflorescence-supporting branches short, 0.8–3.5(5) cm long, leafless but often with 1(2) nodes, or rarely with leaves.
Fruit black, shiny, 7–9 mm in diameter; pedicels slightly accrescent; calyx limb persistent.
Seeds dark, 4.5–5 mm wide, slightly rugulose on convex face.
Flowers fragrant.
