Tree to 30 m tall. The trunk of larger trees can develop buttresses towards the base. Not forming a lignotuber.Bark of young but reproductive trees entirely smooth; older trees develop a rough ± tessellated grey-brown stocking over lower trunk to ca 5 m with the upper trunk and limbs smooth-barked. Smooth-bark greenish grey to white, often shiny.Branchlets have elongated oil bodies in the pith; surface may be setose or glabrous.Juvenile growth (coppice or field seedlings to 50 cm): stem rounded to square in cross-section, densely setose; juvenile leaves always petiolate, alternate, cordate to ovate or elliptical, (5.5)9–14.5 cm long, (4.5)6–10.5 cm wide, base peltate or lobed, discolorous, green; often glossy above, setose on both surfaces.Crown of reproductive trees frequently of setose ovate intermediate leaves but may also develop glabrous lanceolate to narrowly lanceolate true adult leaves. The following description includes both types of leaf.Crown leaves alternate, petiole 1–2.4 cm long; blade ovate or cordate to lanceolate, 6–16 cm long, 1.5–8.5 cm wide, base lobed, rounded or truncate on intermediate leaves, tapering to petiole on adult leaves, margin entire, apex pointed, discolorous, dull or glossy, green, setose or glabrous, penniveined, very densely reticulate, intramarginal vein parallel to and just within margin, oil glands island, numerous, small.Inflorescence terminal compound, peduncles 0.5–2.4 cm long, buds 3 or 7 per umbel, sessile or shortly pedicellate (pedicels to 0.5 cm long). Mature buds ovoid to obovoid, 0.7–0.8 cm long, 0.5–0.7 cm wide, green to creamy, smooth, scar present (outer operculum shed in fragments well before flowering), operculum rounded to conical to slightly beaked, stamens inflexed, anthers ± cuboid, versatile, dorsifixed, dehiscing by longitudinal slits (non-confluent), style long, stigma blunt or mop-like, locules 3, the placentae each with ± 7 vertical ovule rows or the rows indistinct. Flowers white.Fruit sessile or shortly pedicellate (pedicels 0–0.2 cm long), urn-shaped or, if lacking the short neck, truncate-globose, 0.9–1.4 cm long, 0.8–1.4 cm wide, disc descending, valves 3, enclosed.Seeds reddish brown and shiny, 1.2–3 mm long, irregularly ovoid, often ± angular but without sharp ridges ventrally, dorsal surface smooth and at times with a longitudinal keel, not winged, hilum ventral.Cultivated seedlings (measured at ca node 10): cotyledons reniform to orbicular; stems rounded to square in cross-section, densely setose; leaves always petiolate, opposite for 3 or 4 nodes then alternate, ovate to elliptical, 10–14.5 cm long, 4.5–9 cm wide, base rounded for lowest 2 nodes then peltate, discolorous, green, prominently setose.

Tree to 30 m. Juvenile leaves broadly ovate, peltate; petioles and veins hairy. Adult leaves narrowly to broadly lanceolate, acuminate, not commonly seen, as juvenile and intermediate leaves frequently form crown of mature trees; lamina 10–14 cm long, 1–3.5 cm wide, green; lateral veins distinct, at 45°–55°; intramarginal vein up to 1 mm from margin; petiole 5–20 mm long. Peduncle terete, 5–20 mm long; pedicels absent or up to 3 mm long. Operculum hemispherical, apiculate, 1–3 mm long, 3–6 mm wide; hypanthium cupular, 6–8 mm long, 4–8 mm wide. Fruits 8–10 mm long and wide.
