Description
Eucalyptus racemosa is a tree that typically grows to a height of 15–20 m (49–66 ft), rarely a mallee, and forms a lignotuber. It has smooth, mottled white, yellow, grey or cream-coloured bark with insect scribbles. Young plants and coppice regrowth have dull green, egg-shaped leaves that are 50–170 mm (2.0–6.7 in) long, 25–85 mm (0.98–3.35 in) wide and petiolate. Adult leaves are the same shade of glossy green on both sides, lance-shaped to curved or egg-shaped, 65–200 mm (2.6–7.9 in) long and 10–35 mm (0.39–1.38 in) wide on a petiole 10–25 mm (0.39–0.98 in) long. The flower buds are usually arranged in leaf axils in groups of between seven and fifteen on an unbranched peduncle 5–25 mm (0.20–0.98 in) long, the individual buds on pedicels 3–6 mm (0.12–0.24 in) long. Mature buds are oval, 3–5 mm (0.12–0.20 in) long and 2–3 mm (0.079–0.118 in) wide with a rounded or conical operculum. Flowering mainly occurs from July to September and the flowers are white. The fruit is a woody, cup-shaped, conical or hemispherical capsule 3–6 mm (0.12–0.24 in) long and 4–7 mm (0.16–0.28 in) wide with the valves near rim level.[3][4][5]
Taxonomy
Eucalyptus racemosa was first formally described in 1797 by the botanist Antonio José Cavanilles in his book Icones et Descriptiones Plantarum.[6][7] The specific epithet (racemosa) is a Latin word meaning "having racemes", which is a misnomer, as it does not have flowers in racemes.[8]
Distribution and habitat
Ecology
The distinctive scribbles often found on the bark of this eucalypt are caused by the scribbly gum moth, Ogmograptis racemosa.[10]
