Eucalyptus fibrosa

Eucalyptus fibrosa, the broad-leaved red ironbark, is a medium-sized to large tree of the Myrtaceae endemic to eastern Australia, typically 15-35 m tall with a single straight trunk and an open, irregular crown. The bark is deeply furrowed, hard, dark grey to almost black 'ironbark' persisting to the smallest branches and impregnated with kino. Juvenile leaves are ovate to almost orbicular, 5-10 cm long and 4-8 cm wide, sessile or shortly petiolate, greyish-green and held opposite for many pairs. Adult leaves are alternate, broadly lanceolate to ovate, 8-17 cm long and 1.5-5 cm wide, dull green to greyish on both surfaces, with conspicuous oil glands and reticulate venation; petioles are 1.5-3 cm long. Inflorescences are axillary or terminal panicles of seven-flowered umbellasters with a flattened peduncle 5-12 mm long. Buds are ovoid to diamond-shaped, 5-9 mm long with a conical to slightly beaked operculum about as long as the hypanthium. Flowers are white to cream. Fruits are hemispherical to broadly cup-shaped capsules 5-8 mm in diameter with a strongly descending disc and three or four enclosed or near-rim valves. The species grows in dry sclerophyll woodland on poor, often clayey soils.
