Characteristics

Tree to 20 m tall or rarely a mallee. Forming a lignotuber. Bark smooth, often powdery, mottled grey, white, yellow, cream or pale orange, with scribbles. Juvenile growth (coppice or field seedlings to 50 cm): stem rounded in cross-section; juvenile leaves shortly petiolate, ovate-elliptic, opposite for 3 to 6 nodes then alternate, ovate to falcate, 5–17 cm long, 2.5–8.5 cm wide, base rounded or tapering obliquely to petiole, dull, blue-green to green. Adult leaves alternate, petiole 1–2.5 cm long; blade lanceolate to falcate or ovate, 6.5–20(22) cm long, 1–3.5 cm wide, base oblique or tapering to petiole, concolorous, usually glossy, green, side-veins at an acute or wider angle to midrib, sparsely reticulate, intramarginal vein parallel to and well removed from margin, oil glands mostly island. Inflorescence usually axillary unbranched, sometimes terminal compound, slender peduncles 0.5–2.5 cm long, buds 7 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, smooth, scar absent, operculum rounded to conical or sometimes beaked, stamens inflexed, usually with a few outer staminodes, anthers reniform to cordate, versatile, dorsifixed, dehiscing by confluent slits, style usually short, stigma tapered, locules 3 or 4, the placentae each with 2 vertical ovule rows. Flowers white. Fruit pedicels 0.1–0.5 cm long, cup-shaped, obconical or hemispherical, 0.3–0.6 cm long, 0.4–0.7 cm wide, disc raised-convex or annular to level, reddish brown, valves 3 or 4, near rim level. Seeds brown or reddish brown, 1.2–2 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 5 or 6 nodes then alternate, and conspicuously petiolate, ovate, 5–13 cm long, 2.5–6.2 cm wide, base truncate to rounded, later becoming slightly oblique, margin entire, apex pointed, dull, grey-green to green.
