An evergreen tree. It grows to 15-18 m high and spreads to 5-15 m across. The stem is erect and smooth. It arises from a lignotuber. It has powdery white bark. The crown is open and spreading. The leaves are light green and sword shaped and hang down. They are smooth and often with a wavy edge. They taper to a tip and are 8-20 cm long by 0.9-5.5 cm across. The leaf stalk is 0.5-2 cm long. The young leaves are produced opposite each other and are bluish grey with short stalks. Trees in some areas can lose most of their leaves during the dry season. The flower buds are oval and in groups of 3-6. The flowers are small and white. They are produced in the axils of upper leaves or at the ends of branches. The fruit are small, dark brown, rough capsules. They are thin walled and papery. The capsules are 0.8-1.2 cm long by 0.7-0.9 cm wide.
Tree to 15 m. Bark smooth, white or grey-white throughout. Juvenile leaves shortly petiolate, oblong or elliptic to broadly lanceolate, acute or acuminate, glabrous or minutely and sparsely setose, undulate. Adult leaves alternate, petiolate, narrowly to broadly lanceolate; lamina 5–18 cm long, 1.2–4.5 cm wide, light green or yellow-green; lateral veins fine, at 40°–60°; intramarginal vein up to 1 mm from margin; petiole terete, 1–2.5 cm long. Conflorescence axillary or apparently terminal condensed corymbose panicle; umbels 7–11-flowered; peduncle terete, 4–7 mm long; pedicels 4–7 mm long. Buds ovoid to clavate; operculum 1–2 mm long, 5–6 mm wide; hypanthium obconical, 5 mm long, 4–6 mm wide. Fruits cylindrical, abruptly rounded at base, 7–10 mm long, 6–9 mm wide. Seeds not winged but with narrow margins.
