Eucalyptus deglupta is a huge evergreen tree of up to 60 (max. 75) m tall; bole generally of good form, 50-70% of the tree height, up to 240 cm in diameter, sometimes with buttresses 3-4 m high; bark smooth, yellow, brown, and purple, but green after flaking; twigs 4-sided, often with 4 longitudinal wings. Juvenile leaves opposite, ovate to lanceolate; adult leaves opposite to subopposite, rarely alternate, shortly petiolate, held almost horizontal on branches, ovate to ovate-lanceolate or acuminate, thicker than juvenile leaves, 7.5-15 (max. 20) x 5-7.5 (max. 10) cm. Flowers 3-7 umbels in terminal or axillary panicles 5-20 x 5-18 cm; pedicels terete or slightly angular, about 5 mm long; young buds small, green with double opercula; developed buds pale green or cream, globular, apiculate, 0.2-0.4 x 0.2-0.5 mm, operculum hemispherical, apiculate and wider than long; flowers with many white to pale yellow stamens 2-10 mm long, strongly reflexed in the unopened bud; anther dehiscing by separate slits. Fruit pedicallate, hemispherical, with 3-4 valves, thin, deltoid, exserted to 2 mm, making the capsule appear globular, 3-5 x 3-5 mm, and disc very narrow; mature fruits brown to dark brown, containing 3-12 well-formed seeds per valve; seeds minute, brown, flattened, with a small terminal wing. The genus Eucalyptus was described and named in 1788 by the French botanist l’Héritier. The flowers of the various Eucalyptus species are protected by an operculum, hence the generic name, which comes from the Greek words ‘eu’ (well), and ‘calyptos’ (covered).
