Morphology General Habit
Bush or shrubby tree 3–9 m. tall; young branches glabrous; older branches with pale brown or grey-brown peeling bark.
Morphology Leaves
Leaves glabrous; blades often drying grey or greyish-brown, very narrowly elliptic to elliptic or occasionally tending to be oblanceolate, 3.5-15 cm. long, 1.5–5.4 cm. wide, apex acuminate or less often acute, base narrowly cuneate to attenuate; bacterial nodules dot-like to linear, along the midrib and lateral nerves plus a few scattered; petiole 0.9–3.8 cm. long; stipule-limbs thinly or very thinly membranous and translucent, truncate, caducous, 2–7 mm. long, with caudate tip up to 3 mm. long.
Morphology Reproductive morphology Inflorescences
Corymbs terminal on main or lateral branches 4.3–13 cm. long with up to 5 nodes and ± 2 pairs of leaves near the apex; compact to moderately compact, 1.7–3.5 cm. across; primary branches up to 4 mm. long, glabrous; secondary branches usually present; pedicels up to 6 mm. long, glabrous; bracts 3–7 mm. long, membranous to thinly membranous, with very few silky hairs inside.
Morphology Reproductive morphology Flowers Calyx
Calyx glabrous; tube 1–1.25 mm. long; limb-tube 0.25–1 mm. long, slightly wider than the tube; lobes lanceolate, 2–7 mm. long, 1–2 mm. wide (in flowering specimens) tending to reflex, often with nerves apparent.
Morphology Reproductive morphology Flowers Corolla
Corolla-tube 0.5–1 cm. long, 1–1.5 mm. wide at top, glabrous outside, not hairy at throat; lobes oblong to oblong-lanceolate, 3–6.5 mm. long, 1–2 mm. wide, acuminate.
Morphology Reproductive morphology Fruits
Fruit, blackish grey, 6–7 mm. in diameter, glabrous; calyx-limb persistent, accrescent; inflorescence-branches and pedicels accrescent.
Morphology Reproductive morphology Seeds
Seeds ± 5 mm. wide, rugulose on convex face.
