Leaves are glabrous, widely elliptic to ovate or also rounded and can reach a length of about 10–35 mm (0.39–1.38 in), with a petiole of about 5–10 mm (0.20–0.39 in). The flowers are rather small, 1–1.5 cm (0.39–0.59 in) long and are born from the axils of the leaves. The calyx lobes reach 2–3 mm (0.079–0.118 in). Corolla is bell-shaped or urn-shaped, white or greenish. Anthers reach 1.5–2 mm (0.059–0.079 in). Fruits can reach 10–15 mm (0.39–0.59 in).
