Leaves 0.8–5.5 × 0.3–3.3 cm, elliptic to almost round, usually obtuse or obtusely acuminate at the apex, cuneate and contracted into the petiole, thin in texture, ± shortly pubescent on midrib above, with hairy domatia in leaf axils beneath or ± densely shortly bristly pubescent on both surfaces; true petioles short, rarely up to 1 cm long together with the narrowed leaf base, ciliate; stipules 1–2 mm long, pubescent, the persistent bases rendering the short shoots nodular.
Shrub 1–2.5 m or tree to 4 m tall, unarmed, much-branched; young branches grey, pubescent.
Calyx glabrous to pubescent; tube 1–2 mm long; limb-tube 1–1.5 mm long; lobes 0.5–1.5(2.5) mm long, persistent in fruit.
Pedicels 1–2 mm long, sometimes lengthening to 4–5 mm in fruit.
Anthers mostly included, the tips exserted for 2 mm; pollen presenter exserted for 5–6 mm.
Corolla white or cream-coloured turning dark yellow, glabrous outside; tube 5–7 mm long; lobes (3)4–6 × 1.7–2.5(5.5) mm.
Seeds pale chestnut-coloured, c. 2.5 × 1.8 × 0.7 mm.
Fruit 5–7 mm long and wide, ellipsoid to ± subglobose, glabrous or slightly to densely setulose or pilose.
Shrub, 1.0-2.5 m high. Corolla tube developed with upper funnel-shaped part and lower cylindrical part. Style narrowly clavate, winged at apex. Anthers apiculate. Fruits small, seeds compressed ovoid-angular, not in a pulp. Flowers white, cream or yellow.
