Corymbia dallachiana

Corymbia dallachiana is a tree that typically grows to a height of 15 m (49 ft), sometimes more, and forms a lignotuber. It has smooth white to cream-coloured and pinkish bark that is shed in thin patches. Sometimes there is a short stocking of rough grey bark at the base of the trunk. Young plants and coppice regrowth have leathery elliptical, later egg-shaped to lance-shaped leaves that are 100–260 mm (3.9–10.2 in) long, 35–150 mm (1.4–5.9 in) wide and petiolate. Adult leaves are the same shade of green on both sides, lance-shaped or curved, 93–270 mm (3.7–10.6 in) long and 9–34 mm (0.35–1.34 in) wide, tapering to a petiole 12–38 mm (0.47–1.50 in) long. The flower buds are arranged in leaf axils on a branched peduncle up to 3 mm (0.12 in) long, each branch of the peduncle usually with three buds on pedicels 1–6 mm (0.039–0.236 in) long. Mature buds are pear-shaped, 5–7 mm (0.20–0.28 in) long and 4–6 mm (0.16–0.24 in) wide with a rounded operculum. Flowering has been observed in November and December and the flowers are white. The fruit is a woody cup-shaped, cylindrical or barrel-shaped capsule 9–13 mm (0.35–0.51 in) long and 7–10 mm (0.28–0.39 in) wide with the valves enclosed in the fruit or at rim level.[2][3][4][5]

Dallachy's ghost gum was first formally described in 1867 by George Bentham who gave it the name Eucalyptus tessellaris var. dallachiana and published the description in Flora Australiensis.[6][7] In 1995 Kenneth Hill and Lawrence Alexander Sidney Johnson raised the variety to species status as Corymbia dallachiana in the journal Telopea.[4][8] The specific epithet (dallachiana) honours John Dallachy.[2]

Corymbia dallachiana grows in grassy woodland on plains and on creek levees east of a line from Coen to Jericho and south from Bathurst Bay to Rockhampton and Emerald.[2][4][9]

This eucalypt is classified as of "least concern" under the Queensland Government Nature Conservation Act 1992.[10]
