Tree 15 m tall. Forming a lignotuber.Bark rough, grey to orange-brown and thinly tessellated over lower trunk only, becoming smooth above, grey and cream, or essentially smooth throughout with scaly patches of rough bark on the trunk.Branchlets lack oil glands in the pith; smooth.Juvenile growth (coppice or field seedlings to 50 cm): stems rounded in cross-section, setose with bristle-glands; juvenile leaves always petiolate, opposite for ca 25 nodes then becoming alternate, ovate to lanceolate, 5.5–9.5 cm long, 1.3–2(4) cm wide, base rounded to tapering, green, setose with bristle-glands. Adult leaves alternate, petioles 0.8–2.6 cm long; blade lanceolate to falcate, 10–22 cm long, 0.9–2.7 cm wide, base tapering to petiole, margin entire, apex pointed, concolorous or slightly discolorous, glossy, green, side-veins greater than 45° to midrib, reticulation very dense, intramarginal vein very close to edge or confluent with edge, oil glands absent.Inflorescence terminal compound, peduncles rounded to angular, 0.6–1.8 cm long, buds 7 per umbel, pedicels slender 0.3–1.2 cm long. Mature buds pyriform to obovoid, ca 0.7 cm long, ca 0.5 cm wide, glossy, smooth, scar absent (both opercula shed together at flowering), operculum shallowly rounded and often apiculate, stamens inflexed, all fertile, anthers oblong, dorsifixed, versatile, dehiscing by longitudinal slits, style long and straight, stigma blunt and ?papillose, locules 4, the placentae each with few ovules, not clearly arranged in rows. Flowers white.Fruit pedicellate (pedicels 0.2–1.2 cm long), barrel-shaped to urceolate with a short neck that is erect or flared slightly at the rim, 1–1.4 cm long, 0.8–1.1(1.3) cm wide, smooth, disc descending vertically, valves 4, enclosed.Seeds brown to blackish brown, 6–9 mm long, ellipsoidal with terminal wing, hilum ± ventral. Cultivated seedlings (measured at ca node 10): cotyledons large, reniform; stems rounded in cross-section, prominently setose with bristle-glands; leaves always petiolate (petioles to 1 cm), opposite for at least 12 nodes, or becoming alternate at ca node 10, ovate to lanceolate, ca 5–11 cm long, ca 1.5–4 cm wide, base rounded or tapering, apex pointed, green, ± concolorous, setose on both surfaces.
