Description:

Tree commonly to 20 m, occasionally to 45 m. Bark smooth throughout, white, grey, brown or red. Juvenile leaves ovate to broadly lanceolate, green, grey-green or blue-green, slightly discolorous. Adult leaves lanceolate to narrowly lanceolate, acuminate, moderately thick; lamina 8-30 cm long, 0.7-2 cm wide, green or grey-green; lateral veins at 40°-50°; intramarginal vein up to 2 mm from margin; petiole terete or channelled, 12-15 mm long. Umbels 7-11- flowered; peduncle slender, terete or quadrangular, 6-15 mm long; pedicels slender, 5-12 mm long. Buds globular-rostrate or ovoid-conical; operculum hemispherical, rostrate or conical, obtuse, 4-6 mm long, 3-6 mm wide; hypanthium hemispherical, 2-3 mm long, 3-6 mm wide. Fruits hemispherical or ovoid, 5-8 mm long and wide; disc broad, ascending; valves 3-5. Seeds yellow.

Common Name:

River Red Gum.

Distribution:

Occurs in most of the Australian mainland except southern WA, south-western SA, and the eastern coastal areas of Qld, NSW. and Vic. Grows along and near watercourses, sometimes extending to hills or ranges, usually in open forest and woodland.

Notes:

Usually a tall tree with smooth, white, grey, brown or red bark, globular-rostrate or ovoid-conical buds on slender pedicels, and hemispherical or ovoid fruits with a broad ascending disc. The most widespread species in the genus, consequently exhibiting great variation, with some authorities preferring to recognise several taxa. The wood is hard and durable and has been used for many purposes, including railway sleepers, flooring, fencing, plywood, veneer, turnery and firewood. The trees are good producers of pollen and nectar for honey, and the honey is first grade.
