[2][3] In his book Eucalyptographia of 1883, under the heading "Eucalyptus gracilis", Ferdinand von Mueller noted - Either as a variety or perhaps even as a species can be distinguished from E. gracilis as Eucalyptus gathered by the lamented late Monsieur A. Thozet in his last botanical journey to Expedition-Range, during which he became a victim of the paludal fever, to which this excellent man so sadly succumbed.

This Eucalyptus, which should bear his name, can be distinguished by its longer leaves, narrow-ellipsoid flowerbuds, smaller, not or less conspicuously angular calyces and also smaller and narrower fruit, irrespective of the size of the tree, which rises to a height of 60 feet, according to Mr. E. Bowman and Mr. P. O'Shanesy, who noticed it near the Mackenzie- and Comet-River.

[5][6] In 1906, Richard Thomas Baker raised the variety to species status as Eucalyptus thozetiana in Proceedings of the Linnean Society of New South Wales.

It is widespread between Emerald, Junda and the Darling Downs in Queensland and near Arltunga in the south of the Northern Territory.

[2][3][9] This eucalypt is classified as "least concern" under the Queensland Government Nature Conservation Act 1992,[10] and as "near threatened" in the Northern Territory.
