Leaf blades drying greyish-bronze, discolorous, 6–16.3 × 2.9–8.3 cm, obovate or occasionally broadly obovate or oblanceolate, rounded and usually shortly acuminate at the apex, cuneate at the base, sparsely pubescent to glabrous or scabrid above, pubescent to sparsely pubescent or rarely glabrous beneath; lateral nerves in (8)9–12 main pairs, whitish, acutely angled, often prominent beneath; domatia absent; bacterial nodules few–many, dot-like to elongate, along the nerves and scattered; petiole 0.9–2.5 cm long, pubescent to glabrescent; stipule limbs usually greenish, triangular, 6–14 mm long, cuspidate, pubescent to sparsely pubescent outside, with some silky hairs inside.
Inflorescences compact to moderately lax, typically hemispherical when young, 2–4.7(6) cm across (excluding corollas); primary inflorescence branches 1–10 mm long, pubescent; secondary and tertiary branches present or reduced; pedicels (2)4–7 mm long, pubescent or rarely sparsely pubescent.
Corolla tube 0.8–1.5 cm long, 1.5 mm wide at the top, glabrous or occasionally hairy outside, not bearded at the throat; lobes 3.5–6 × 1.25–2 mm, oblanceolate-oblong, rounded or sometimes acuminate.
Inflorescence-supporting branches 1–18 cm long bearing up to 3 pairs of leaves near the apex, slightly smaller and with shorter petioles than leaves on main branches.
Calyx tube 1 mm long, densely pubescent; limb-tube 0.5–1 mm long, slightly wider than the tube; lobes 3–5(7) × 1–1.25 mm, lanceolate or linear-lanceolate, pubescent.
Shrub 0.5–4.5 m tall; young branches sparsely pubescent to glabrescent or rarely glabrous; older branches covered with thin grey or buff bark.
Fruit 6–8 mm in diameter, shiny, sparsely pubescent, calyx limb persistent; pedicels accrescent.
Seeds greyish, 5–6 mm wide, slightly rugulose on convex face.
