Baron von Mueller refers to this tree in his ' Eucalyptographia ' 

 under E. gracilis, in these words : — " Either as a variety or 

 perhaps, even as a species, can be distinguished from E, gracilis, 

 an Eucalyptus gathered by the lamented late Monsieur 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, more or less conspicuously angular calyces, 

 and also smaller and particularly 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 Rivers." 



Maiden in his " Critical Rivision of Eucalypts" (Part iii. p. 82) 

 also places it as a doubtful variety under E. calycogona Turc, 

 var. gracilis F.v. M., var. Thozetiana, and states, inter alia, 

 " While these specimens (from Expedition Range, Q.; Mackenzie 

 River, Q.; Warrego and Flinders Rivers, Q ) probably belong to 

 E. calycogona, in my opinion these Queensland trees appear to 

 show transit to the narrow-leaved forms of E. odorata. 

 Additional material, including ripe fruits, and further particulars 

 as to habit, bark, timber, &,c, are necessary before the position of 

 this tree can be stated without doubt." 



This Eucalyptus occurs in the interior of Queensland, " mostly 

 on the di'y ridges bordering on the brigalow scrubs, and sometimes 

 extending to them " (O'Shanesy), a location endorsed by the 

 observations of Mr. C. W. Chapman, from whom all the material 

 described in this paper was obtained. 



Leaf- and budding specimens of this Eucalyptus were sent to 

 this Museum as far back as 1898, but it was only recently that 

 complete material had been obtained, after much trouble and 

 expense incurred by Mr. C. W. Chapman in defraying the 

 expense of carting the material to the coast from so far an inland 

 town as G-oondiwindi, and thence to Sydney. 



The fruit, timber and oil constituents at once showed that it 

 was distinct from any recorded species of Eucalyptus, the timber 

 especially so.
