Fruits 2.5–3 × 2–2.5 cm, obovoid- or ellipsoid-subglobose, scarcely 3-lobed, loculicidal, densely echinate, subglabrous except for the processes; processes up to 7 mm long, subulate, curved, sparingly stellate-pubescent.
A shrub or small tree up to 5 m high.
Stipules 5 mm long, subulate, sparingly stellate-pubescent, soon falling.
Petioles 1–7 cm long, stellate-pubescent at first, later glabrescent.
Leaf blades 4–10 × 2–3 cm, lanceolate to elliptic-lanceolate, acuminate at the apex, shallowly and somewhat irregularly glandular-serrulate on the margins, wide-cuneate to rounded at the base, with a pair of small stipitate or subsessile discoid glands on upper surface at the junction with the petiole, chartaceous, minutely glandular-punctate, glabrous or subglabrous on both surfaces, if subglabrous then with very few scattered stellate hairs on the lower midrib and lateral nerves; 5-nerved from the base, lateral nerves in 10–18 pairs, scarcely prominent.
