Mallet to 7 m tall. Lignotuber absent. Bark rough, flaky and grey over all or part of trunk, smooth above grey to pale grey over salmon pink. Branchlets have oil glands in the pith. Juvenile growth (coppice or field seedlings to 50 cm): not seen. Adult leaves alternate, petioles 0.5–1.3 cm long; blade narrowly lanceolate, (4.5)5.8–9.5 cm long, (0.7)0.9–1.5 cm wide, base tapering to petiole, margin entire, apex pointed, concolorous, dull, green to greenish blue, side-veins greater than 45° to midrib, reticulation moderate to dense, intramarginal vein remote from margin, oil glands island and intersectional. Inflorescence axillary unbranched, peduncles widen apically, 0.7–1.5 cm long, buds ?9 or 11, pedicellate (pedicels 0.3 cm long). Mature buds fusiform (1.3–1.5 cm long, 0.3 cm wide), often hooked apically, scar present, operculum conical, twice the length of the hypanthium about equal to it at the join or only slightly narrower, few outer stamens erect, most stamens variably deflexed, anthers cuboid, versatile, dorsifixed, dehiscing by longitudinal slits, style long and straight, stigma rounded, locules 3(4), the placentae each with 4 vertical rows of ovules. Flowers pale yellow. Fruit pedicellate (pedicels 0.2–0.3 cm long), cylindrical to barrel-shaped, 0.6–0.7 cm long, 0.4–0.5 cm wide, disc descending vertically, valves 3(4), about rim level. Seeds pale brown to straw-coloured, 0.7–1.5 mm diameter, sub-spherical, surface smooth, hilum ventral/terminal. Cultivated seedlings (measured at node 10): cotyledons Y-shaped (bisected); stems rounded in cross-section, smooth or warty; leaves shortly petiolate, opposite for ca 3 or 4 nodes then alternate, lanceolate, 6–8.5 cm long, 1–2 cm wide, green, dull.
