Mallet to 12 m tall. Non-lignotuberous.Bark smooth throughout, grey over fawn to brown and salmon, shedding in long ribbons.Branchlets have oil glands in the pith. Juvenile growth (coppice or field seedlings to 50 cm): not seen.Adult leaves alternate, petioles 0.8-1.9 cm long; blade linear to narrowly lanceolate, (4.6)6–10 cm long, 0.7–1(1.4) cm wide, base tapering to petiole, margin entire, apex pointed, concolorous, very glossy, dark green, side-veins at an acute or wider angle to midrib, reticulation moderate to dense, intramarginal present, oil glands intersectional and some island. Inflorescence axillary unbranched, peduncles angular, 0.4–1.3 cm long, buds 3 per umbel, pedicellate, pedicels 0.3–1.1 cm long. Mature buds obovoid to pyriform (1–1.5 cm long, 0.8–1.2 cm wide), deeply longitudinally ribbed (corrugate) from top of operculum to base of hypanthium (ca 10-11 ribs), scar present from outer operculum shedding early in development, inner operculum rounded, stamens inflexed, anthers cuboid to wedge-shaped, versatile, dorsifixed, dehiscing by longitudinal slits, style long and straight, stigma broadly conic, locules 4(5), the placentae each with 4 vertical rows of ovules. Flowers creamy white. Fruit pedicellate, pedicels 0.3–1.1 cm long, usually obconical to cupular, always with prominent ribs, 0.9–1.2 cm long, 1–1.3 cm wide (incl. ribs), disc level or sometimes descending obliquely, valves 4(5), near rim level. Seeds reddish brown and glossy, 1.5–3 mm long, flattened-ovoid and more or less angular, dorsal surface lacunose or not, scarcely reticulate, hilum ventral.Cultivated seedlings (measured at node 10): (after Nicolle 2009) cotyledons reniform; stems slightly square in cross-section, slightly to moderately warty; leaves always petiolate, [opposite for a few nodes then alternate,] ovate, size not recorded, slightly glossy, green.
