Tree to 15 m tall. Forming a lignotuber. Bark rough throughout, tessellated, grey, grey-brown and red to orange. Juvenile growth (coppice or field seedlings to 50 cm): stem rounded in cross-section, hairy on early growth; juvenile leaves petiolate, opposite for ca 5 to 12 nodes then becoming alternate, petiolate, narrowly lanceolate to elliptical, 6–14.5 cm long, (0.9)1.2–5 cm wide, base tapering to petiole, discolorous, green, setae present on lower leaves. Adult leaves alternate, petiole 1–2.2 cm long; blade lanceolate, 6–18 cm long, 1–3 cm wide, base tapering to petiole, discolorous, glossy, green, strongly penniveined, densely to very densely reticulate, intramarginal vein parallel to and just within margin, oil glands island or obscure. Inflorescence terminal compound, peduncles 0.5–1.7 cm long, buds 7 per umbel, pedicels 0.3–1 cm long. Mature buds obovoid to pyriform, 0.7–1.2 cm long, 0.4–0.8 cm wide, slightly scurfy, scar absent (both opercula shed together at flowering), operculum rounded to conical to beaked, stamens inflexed, anthers cuboid to oblong, versatile, dorsifixed, dehiscing by longitudinal slits (non-confluent), style long, stigma tapered, or mop-like, locules 3 or 4, the placentae each with 3, 5 or indistinct vertical ovule rows. Flowers white. Fruit pedicellate (pedicels 0.2–1.1 cm long), urceolate varing to barrel-shaped, when barrel-shaped with a slightly flared rim, 1.2–2.5 cm long, 0.9–1.6 cm wide, length always Seeds brown or reddish brown, 9–11 mm long, ellipsoidal with terminal wing, dorsal surface smooth, hilum ventral. Cultivated seedlings (measured at ca node 10): cotyledons reniform to orbicular; stems rounded in cross-section, shortly setose until node 2–8 then smooth; leaves shortly petiolate, opposite for 6 to 13+ nodes then sub-opposite to alternate, narrowly lanceolate to narrowly elliptic-oblong, 7–13 cm long, 1.3–2.5(3.0) cm wide, base tapering, discolorous, slightly glossy or dull, mid-green above; lamina sparsely setose on lower side to node 2–8 then glabrous.
