Leaves glabrous; blades 4–29 × 1.5–12.4 cm, oblanceolate or narrowly to broadly elliptic, obtuse to acuminate or broadly to finely acuminate at the apex, obtuse to cuneate at the base, coriaceous, very shiny above, midrib and lateral nerves usually drying cream in colour, prominent beneath; lateral nerves in 5–8 main pairs; tertiary nerves rather coarsely reticulate, raised on both surfaces; domatia pocket-like, ciliate or sparsely pubescent; bacterial nodules linear, restricted to the midrib and less often lateral nerves; petiole 0.2–5.5 cm long; stipule limbs 2–4 mm long, truncate, sometimes corky around the margin; arista 1–6 mm long, occasionally slightly keeled.
Corymbs terminal on main and lateral leafy branches, moderately compact, 3–8.5 cm across (excluding corollas); primary inflorescence branches 0.5–2.5 cm long, glabrous or rarely puberulous; secondary to tertiary branches present; pedicels up to 5 mm long, puberulous; bracts 3–4 mm long, stipule-like; bracteoles inconspicuous.
Calyx puberulous, rarely sparsely puberulous; tube 1 mm long; limb-tube 0.75–1 mm long, c. 3 times wider than the tube; lobes 0.75–2 × (1.2)1.5–2.2 mm, transversely oblong-semicircular, pubescent inside, overlapping in bud.
Corolla tube 5–7(9) mm long, (1.75)2.5 mm wide at the apex, glabrous except for the densely bearded throat; lobes 5–10 × 1.5–2.5(3.5) mm, ovate-oblong, obtuse to rounded.
Fruit purplish-red or black, (6)7–8 mm in diameter, shiny, glabrous or sparsely puberulous, calyx lobes persistent, pedicels lengthening slightly.
Evergreen shrub or small tree 1–7 m tall; young branches glabrous; older branches without corky bark.
Seed blackish with light brown area around the excavation, 5 mm wide, very finely rugulose.
