They are small trees varying between 1.80 to 12 m in height. The bark is dark brown, sometimes soft and generally thin and deciduous. The young branches are smooth or very lightly puberulent. Leaves have oblong to oblong-oval laminas that measure 2.5 to 17.5 cm by 1.1 to 8.3 cm in length. They are rounded at the tip and cuneiform at the base. The midvein is prominent and yellow in colour. However, venation pattern is prominent on the lower leaf surface. The petiole has an orange coloured base and measures 0.5 to 3.5 cm long. The stipules are fused in a cylindrical sheath and can be 3 to 10 mm long.

  The flowers are fragrant, while the inflorescence is highly branched reaching up to 13 cm in girth. The peduncles are 1 to 6 cm long, while the pedicels are very short or virtually absent. The bracts are oval to ovate-lanceolate, highly spread out and between 3 to 5 mm. The bracteoles on the other hand measure 1 to 1.5 mm and are oval. The calyx is 2 to 3 mm long with the lobes being 0.5 to 0.8 mm and the tube’s margins being undulated. The corolla is white, somewhat waxy, pubescent and with a tube measuring 0.9 to 1.6 cm.

 The styles usually measure 1.6 mm, are thick and fleshy with a triangular cross-section. The fruit is white, cream or bluish, ellipsoidal 7 to 10 mm by 6 to 8 mm.
