Tree to 15 m tall. Forming a lignotuber. Bark smooth, rarely powdery, silvery white, cream, pale grey, orange-yellow, with scribbles. Juvenile growth (coppice or field seedlings to 50 cm): stem rounded in cross-section, warty or smooth; juvenile leaves sessile at first then shortly petiolate, opposite for 6 to 8 pairs becoming alternate, lanceolate to narrowly lanceolate or falcate, 7–14 cm long, 1.5–4 cm wide, base rounded or tapering, dull, green to blue-green. Adult leaves alternate, petiole 0.7–2 cm long; blade narrowly lanceolate to lanceolate, 5.5–15 cm long, 0.8–2.5 cm wide, base tapering to petiole, concolorous, glossy or dull, green to blue-green, side veins acute, sparsely reticulate, intramarginal vein parallel to and well removed from margin, oil glands island. Inflorescence axillary unbranched, or sometimes terminal compound, peduncles 0.7–1.1 cm long, buds 9 to ?15 per umbel, pedicels 0.3–0.6 cm long. Mature buds obovoid, 0.3–0.5 cm long, 0.2–0.3 cm wide, green to yellow, scar absent, operculum rounded, stamens inflexed, with outer staminodes, anthers reniform to cordate, versatile, dorsifixed, dehiscing by confluent slits, style short, stigma tapered, locules 3 or 4, the placentae each with 2 vertical ovule rows. Flowers white. Fruit pedicellate (pedicels 0.3–0.6 cm long), cup-shaped, hemispherical or truncate-globose, 0.3–0.6 cm long, 0.4–0.6 cm wide, disc slightly raised-convex to annular or level, reddish brown, valves 3 or 4, near rim level. Seeds brown to reddish brown, 0.8–2 mm long, pyramidal or obliquely pyramidal, dorsal surface smooth, hilum terminal. Cultivated seedlings (measured at ca node 10): cotyledons reniform to orbicular; stems rounded in cross-section, warty or smooth; leaves ± sessile to shortly petiolate, ovate-elliptic and opposite for 6 to 10 nodes then alternate, and conspicuously petiolate, ovate-lanceolate, 5.5–12 cm long, 1.5–3.5 cm wide, rounded then tapering, margin entire, apex pointed, concolorous, dull, grey-green to green.
