Species

Angiosperms > Myrtales > Myrtaceae > Corymbia

Characteristics

Tree 6 m tall, ?deciduous in the late dry season. Forming a lignotuber.Bark rough, persistent, blackish grey, tessellated and somewhat straggly over basal part or all of trunk, then becoming smooth, creamy white to pale grey, shedding in thin flakes.Branchlets lack oil glands in the pith; younger branchlets setose to scabrid with bristle-glands. In this species the bristle-glands lack simple hairs.Juvenile growth (coppice or field seedlings to 50 cm): not seen. Crown of intermediate to adult leaves, opposite or alternate, sessile or shortly petiolate, petioles 0.1–0.5 cm long; blade cordate to ovate to elliptic or lanceolate, (6.3)9–19.5 cm long, 2.7–9 cm wide, ± undulate, base amplexicaul to lobed or rounded, margin entire, apex rounded or broadly pointed, concolorous, dull, green, glabrous to very sparsely setose (if any setae present then restricted to major side-veins, mid-vein and petiole), side-veins at greater than 45° to midrib, reticulation dense to very dense, intramarginal vein present, oil glands obscure. Inflorescence borne on leafless branchlets below new season’s leaf growth, axillary compound, the rhachis consisting of a basal internode ca 0.2–0.5 cm long, a second internode absent or 0.1–0.3 cm long, and peduncles of variable length within a single inflorescence, 0.2–1.5 cm long, buds 7 per umbel, strongly pedicellate (pedicels 0.9–3.2 cm long). Mature buds pyriform, 0.6–0.7 cm long, 0.4–0.5 cm wide, smooth, scar present (outer operculum shed early), operculum shallowly rounded, stamens inflexed, all fertile, anthers oblong, dorsifixed, versatile, dehiscing by longitudinal slits, style long and straight, stigma tapered, locules 3, the ovules arranged in 3 or 4 ± distinct vertical rows on the placentae. Flowers creamy white.Fruit pedicellate (pedicels 0.9–3.2 cm long), cylindrical to barrel-shaped, rarely slightly urceolate, 0.8–1.5 cm long, 0.7–1.2 cm wide, thin-walled, disc descending vertically, valves 3, enclosed.Seeds not seen (presumably brown, saucer-shaped, smooth, hilum ventral, like those of other ghost gums). Cultivated seedlings (measured at ca node 10): not grown.
