Corymbia dallachiana is a tree that typically grows to a height of 15 m (49 ft), sometimes more, and forms a lignotuber.

[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.

[6][7] In 1995 Kenneth Hill and Lawrence Alexander Sidney Johnson raised the variety to species status as Corymbia dallachiana in the journal Telopea.

[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.
