Alstonia scholaris is a globous tree and grows up to 40 m (130 ft) tall. Its mature bark is greyish and its young branches are copiously marked with lenticles. One unique feature of this tree is that in some places, such as New Guinea, the trunk is three-sided (i.e. it is triangular in cross-section). The upper side of the leaves are glossy, while the underside is greyish. Leaves occur in whorls of three to ten; petioles are 1–3 cm (0.39–1.18 in); the leathery leaves are narrowly obovate to very narrowly spathulate base cuneate, apex usually rounded and up to nine inches (23 centimetres) long by up to three inches (8 cm) in width. Lateral veins occur in 25 to 50 pairs, at 80–90° to midvein. Cymes are dense and pubescent; peduncle is 4–7 cm (1.6–2.8 in) long. Pedicles are usually as long as or shorter than calyx. The corolla is white and tube-like, 6–10 mm (0.24–0.39 in); lobes are broadly ovate or broadly obovate, 2–4.5 mm (0.079–0.177 in), overlapping to the left. The ovaries are distinct and pubescent. The follicles are distinct and linear.
