AFFINITIES. 



1 and 2. With. E. maculata Hook, and E. corijmbosa Sm. 

 E. Xoicracnsis undoubtedly possesses characters intermediate between these 

 two species, and the following is the first comparison made between them. 



Under ' Descriptions of New Australia Plants, with occasional other 

 annotations," by Baron von Mueller, in " The Victorian Naturalist," vol. 7, No. 6 

 (October, 1890). p. 77, occur. the words: — 



" • • • • Mr. Baeuerlen has sent from near the Clyde, also specimens of a Eucalypt, which he 

 considers a hybrid between E. corymbosa and E. maculata, in which case the characteristics of the former 

 are prevailing; the leaves, however, are generally narrower, the operculum is double like that of E. maculata, 

 and it separates by a clear transverse line ; the wood also was found much lighter in colour than that of the 

 genuine E. corymbosa. and the bark smooth on the upper portion of the stem as in E. maculata. The 

 flowering time proved later than that of the former; as many as sixteen flowers occur in an umbel; the 

 fruits are generally not so long as those of E. corymbosa." 



See some comments on these specimens at Part LIT, p. 62, of the present work. 

 Mr. Gallagher's Nowra specimens show — 



(a) A smooth bark — a Grey Gum, something like Spotted Gum (E. maculata). 



It has certainly no rough bark like Bloodwood (E. corymbosa). 



(b) A fissile, pale timber, as pale as the palest. One of the specimens has the 



faintest blush of pink in it; this is not unusual in Spotted Gum. It has 

 certainly no dark timber like one of the types of E. intermedia, nor does it 

 closely resemble any of the Bloodwoods. 



The kino of E. Xowraensis appears to be red (like E. corymbosa, &c), not olive- 

 green (like E. maculata). I had only a small quantity, from a crack in a block of wood, 

 and the observation should be repeated when a larger quantity is available. 



On my drawing Mr. Gallagher's attention to this tree, he wrote : " I am now 

 more than ever convinced that this tree is totally distinct from any other species, and 

 more closely resembles Spotted Gum (E. maculata) than any other tree." (26th 

 September, 1921.) I agree with him. 



The angle the secondary veins make with the midrib in E. Noivraensis is 45 

 degrees; in E. maculata the angle is 35-50 degrees, which does not greatly differ, but 

 in E. corijmbosa the angle is from 50 to 65 degrees, which is distinctly different. 



3. With E. intermedia R. T. Baker. 



The only thing we can say about E. Nowraensis and E. intermedia is in reference 

 to the sometimes pale colour of the timber of the latter. But the bark and the texture 

 of the timber of E. intermedia are closer to E. corymbosa than to those of the very 

 different E. Xowraensis. For further remarks see under E. corymbosa.
