Tree to20 m tall. Forming a lignotuber.Bark thin, rough, grey or grey-brown and red, scaly tessellated, variably extending from the base only to all of trunk, smooth above, slightly powdery or not, white to cream or pale grey.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 to ca 3 mm long; juvenile leaves always petiolate, opposite for many nodes, predominantly cordate to ovate but may be ± lanceolate to oblong or even almost orbicular, (3.3)4–14 cm long, 2.5–6.5 cm wide, base lobed to rounded, rarely peltate or truncate, apex rounded and apiculate or broadly pointed, dull greyish green, with sparse bristle-glands and some white simple hairs scattered on both surfaces.Adult leaves alternate, petioles 1–2.8 cm long; blade lanceolate to falcate, 7.5–15(18.4) cm long, 0.9–2.7 cm wide, base tapering to petiole, margin entire, apex pointed, concolorous or slightly discolorous, maturing very glossy, green, smooth, side-veins greater than 45° to midrib, reticulation very dense, intramarginal vein visible but close to margin, oil glands usually present, island or intersectional, one per areole.Inflorescence terminal compound, peduncles relatively slender, 0.5–3 cm long, buds 7 per umbel, pedicels 0.6–3 cm long. Mature buds ovoid to almost cylindrical (0.8–1.5 cm long, 0.5–0.8 cm wide), smooth, scar absent (both opercula shed together at flowering), operculum rounded to bluntly conical, stamens inflexed, all fertile, anthers oblong, dorsifixed, versatile, dehiscing by longitudinal slits, style long and straight, stigma blunt and long-papillose, locules 4, the placentae each with ca 5 indistinct ovule rows. Flowers creamy white.Fruit pedicellate (pedicels (0.6)1–3 cm long), thick-walled, barrel-shaped and sometimes with a slight apical constriction, rim not flared, 1.5–2.5 cm long, 1–1.5(1.8) cm wide, ca 1.5 times longer than wide, smooth, disc descending vertically, valves 4, enclosed.Seeds brown, 7–13 mm long, ellipsoidal with terminal wing, hilum ventral. Cultivated seedlings (measured at ca node 10): cotyledons large, reniform; stems rounded in cross-section, setose with bristle-glands and also with short white simple hairs arising from the epidermis; leaves at least shortly petiolate (petioles to 1.4 cm), opposite for at least 16 nodes, ovate to cordate or lanceolate-elliptic, 5–10 cm long, 1.8–6 cm wide, base rounded on lower leaves, lobed to rounded higher up stem, apex rounded to pointed, dull, green, slightly discolorous, setose with bristle-glands and short white simple hairs on both surfaces.
