About Eucalyptus prava L.A.S.Johnson & K.D.Hill
Eucalyptus prava, commonly called orange gum, is a tree that typically grows to 15 metres (49 feet) tall and forms a lignotuber. It has smooth, mottled bark in shades of grey, orange, and reddish brown. Young plants and coppice regrowth have dull bluish green, egg-shaped leaves that are 45–105 mm (1.8–4.1 in) long, 30–70 mm (1.2–2.8 in) wide, and borne on petioles. Adult leaves are arranged alternately, are the same shade of dull bluish or greyish green on both sides, and are lance-shaped to curved. They measure 55–160 mm (2.2–6.3 in) long and 15–37 mm (0.59–1.46 in) wide, tapering to a petiole 15–26 mm (0.59–1.02 in) long. Flower buds are arranged in leaf axils on an unbranched peduncle 8–20 mm (0.31–0.79 in) long, with individual buds attached to pedicels 2–5 mm (0.079–0.197 in) long. Mature buds are oval, 10–15 mm (0.39–0.59 in) long and 4–6 mm (0.16–0.24 in) wide, with a horn-shaped to conical operculum. Flowering has been recorded in January, and the flowers are white. The fruit is a woody, cup-shaped or hemispherical capsule 3–8 mm (0.12–0.31 in) long and 5–10 mm (0.20–0.39 in) wide, with strongly protruding valves. This eucalypt grows in woodland, most often in poor, shallow skeletal soils formed from granite or sandstone. Its range extends from north of Moonbi in New South Wales northwards to Wallangarra and Stanthorpe in Queensland.
