2. With E. eugenioides Sieb. 



E. Callanii is a smaller tree than the typical E. eugenioides, and it has a more 

 compressed flaky-fibrous bark on the trunk only, which does not stand out in longitu- 

 dinal ridges like the bark of E. eugenioides. The timber is also dissimilar and inferior 

 to that of E. eugenioides. The buds and fruits of both species are, however, almost 

 dentical, but there is considerable diversity between the juvenile leaves of both species. 

 Those of E. eugenioides are narrow, crinkled and stellate, whilst the juvenile leaves of 

 E. Callanii are broad and comparatively smooth. 



3. With E. ultrea R. T. Baker. 



The similarity of these trees is chiefly in the venation of their leaves, but the lateral 

 veins of E. vitrea are even more longitudinal than those of E. Callanii. The floral 

 organs, bark, and juvenile leaves, of course, sharply separate them. 



The " Critical Revision of the Genus Eucalyptus " was commenced by the late J. H. Maiden in 

 1903. At the time of his death there were still several parts to be published — concerning some speaies 

 he had left full notes, concerning others he had left fragmentary notes only, while other species which had 

 not been described, had, in some cases, been under discussion with one or both of us. In editing those 

 parts of the " Revision " unpublished at the time of Mr. Maiden's death we have, in accordance with his 

 wishes, and in order to make the whole work as complete as possible, included species not described 

 during Mr. Maiden's lifetime.
