Leaf blades drying greenish or blue-black, 3.7–9.5 × 1.5–4.7 cm, narrowly obovate to obovate, less often elliptic, lanceolate-elliptic or rarely round, with the apex rounded, obtuse, acute or slightly acuminate, and the base cuneate or rarely ± truncate, papery, dull, glabrous or with a few hairs on midrib above, sparsely pubescent to glabrous beneath; lateral nerves in 6–8 main pairs; domatia absent; bacterial nodules dot-like to elliptic, large, scattered but usually absent from the marginal areas; petiole usually drying blackish, 2–4 mm long, sparsely pubescent or glabrous; stipules truncate to triangular, 3–6 mm long, or shortly connate when developed, acute to acuminate, caducous, often with a line of silky hairs along the scar.
Calyx tube 1–1.5 mm long, glabrous or with very few hairs; limb-tube 1–2 mm long, c. 1½ times wider than the tube, glabrous to sparsely hairy; lobes narrowly linear to linear, often from a triangular base or subulate, 1–4 mm long, 0.25–0.75 mm wide, covered with crisped to straight white hairs, with very few hairs, occasionally only one or two near apex or infrequently glabrous.
Inflorescences subumbellate, moderately compact, 1–3 cm across (excluding corollas), flowers often pendulous; primary inflorescence branches 1–6(8) mm long, glabrous; secondary branches absent or occasionally present; pedicels 1–6 mm long, glabrous; bracts stipule-like, 2–5 mm long, deciduous leaving a line of silky hairs; bracteoles inconspicuous.
Shrub or small tree, 1.5–7(9) m tall, often scandent; young branches glabrous, usually drying black; older branches covered with buff to brown, scarcely flaking bark.
Corolla tube 0.9–1.6(2) cm long, 2 mm wide at the top, glabrous outside, not bearded at the throat; lobes 4–6(8) × 2–2.5 mm, ± oblong, rounded or shortly acuminate.
Inflorescence-supporting branches 1–9 cm long, bearing 0–2 pairs of leaves at the apex.
Fruit black, 1 cm in diameter, shiny, glabrous; calyx limb persistent.
Seed reddish-brown, 5 mm wide, finely rugulose on convex face.
