Tree to 10 m, rarely 20 m tall. Forming a lignotuber.Bark rough to limbs ca 5 cm diameter, tessellated to finely flaky, yellow-brown to yellow-grey with a hint of orange.Branchlets scabrid with setae or their weathered remains; elongated oil bodies often present in the pith.Juvenile growth (coppice or field seedlings to 50 cm): stem rounded to square in cross-section; juvenile leaves opposite, always petiolate, ± orbicular to ovate or elliptical, 6–21 cm long, 4–12 cm wide, base lobed and peltate, green; setose with bristle-glands, becoming scabrid as these weather, on stems, petioles and lamina.True alternate petiolate lanceolate. Adult leaves very rarely formed and then only a very small part of the total crown leaves and still scabrid. Crown predominantly of scabrid juvenile leaves, opposite to sub-opposite or occasionally alternately arranged, petiole 1–2.6 cm long; blade sub-orbicular to ovate-elliptic, (4.3)6–13.5 cm long, 3.5–11 cm wide, flat or undulate, base of most leaves peltate, rarely rounded to lobed, apex rounded or emarginate, margin usually entire, concolorous, dull, green to grey-green, penniveined, densely to very densely reticulate, intramarginal vein parallel to and just within margin, oil glands island.Inflorescence terminal compound, peduncles 0.8–3.2 cm long, buds 7 per umbel, sessile or pedicellate (pedicels to 0.3 cm long). Mature buds obovoid, 0.6–0.7 cm long, 0.4–0.5 cm wide, white on surface due to rubbery cuticle (not wax), scar present (outer operculum shed early), operculum rounded and umbonate to conical, stamens inflexed, anthers ± oblong, versatile, dorsifixed, dehiscing by longitudinal slits (non-confluent), style long, stigma tapered, locules 3, the ovules not arranged in clear vertical rows on the placentae. Flowers white.Fruit sessile or shortly pedicellate (pedicels 0–0.1 cm long), barrel-shaped to urceolate or truncate-globose, 0.7–1.4 cm long, (0.6)0.8–1.2 cm wide, disc descending, valves 3, enclosed.Seeds reddish brown and shiny, 3–6 mm long, boat-shaped with a keel on the smooth and usually cracked dorsal surface, not winged, but some seeds have a short flange at one end, hilum ventral. Cultivated seedlings (measured at ca node 10): cotyledons large, reniform to orbicular; stems rounded in cross-section, setose throughout; leaves always petiolate (to 2.2 cm), opposite at most nodes, sometimes sub-opposite, ovate-elliptic to cordate or broadly lanceolate, 4.5–13 cm long, (1.8)2.5–8 cm wide, base peltate after node 4, margin entire but may be undulate, apex ± rounded, more or less concolorous, dull, green, setose throughout on both sides.
