" A very coinmoa tree all over the Warialda district, both on the hills and 

 on the low lands " (J. L. Boorman) ; No. 10 (Rev. H. M. U. Rupp) ; No. 12, the 

 ordinary broad-leaved form, and No. 81, the narrow-leaved form, Warialda (E. J. 

 Hadley). 



Common all over the Warialda and Bingera district. Many were killed 

 by the last drought. Yallaroi (Eorest Guard Edward Juliusj ; Ashford (W. S. 

 Campbell) ; Acacia Creek, Macpherson Range (W. Dunn). 



Queensland. 

 Morven (collected for F. M. Bailey) ; " Silver-leaved Ironbark," " Of no 

 utility," Maryborough (W. A. Williams) ; " Silver-leaved Ironbark," Brian Pastures, 

 Gayndah (S. A. Lindeman) ; Bockhampton, narrowish leaves (Amalia Dietrich) ; 

 Rockhampton, with normal leaves (R. Simmons); "Box tree of the Mackenzie 

 Biver " (Leichhardt), the narrow-leaved form. A specimen like this shows 

 considerable resemblance to M microtheca, E.v.M. ; King's Creek (E. Bowman) ; 

 " Ironbark," also " Weeping Box," Jericho (H. Deane), leaves medium broad. 

 There is no difference between them. Mr. Deane, a considerable authority on 

 Eucalyptus, labels them " W^eeping Box," " Mackenzie River Box — White stem." 

 See p. 71 ; Stannary HiUs (Dr. T. L. Bancroft). 



Western Australia, 

 " Ironbark." Isdell River (W. V. Eitzgerald). Narrowish leaves, and rather 

 small fruits. Sent as E. crebra. I am not aware that E. melanophloia has been 

 previously recorded from Western Australia. 



AFFINITIES. 



1. With E. pruinosa, Schauer. 



This was pointed out by Mueller in the " Eucalyptographia." So far as 

 we know, however, the leaves of B. pruinosa are homoblastic. The leaves of 

 U. pruinosa are, as a rule, larger, while the fruits are certainly so. 



2. With E. erebra, E.v.M. 



Already referred to under E. crebra, p. 67. 



3. With E. microtheca, E.v.M. 



Already referred to. The leaves of U. microtheca are much less heteroblastic 

 than those of E. melanophloia. 



4. With E. cinerea, E.v.M. 



Bentham says : "It {E. melanophloia) sometimes resembles E. cinerea, but 

 differs in the bark, the stamens, and the fruit. {B.Fl. iii, 221.) I will refer to this 

 afl&nity, and to E. cinerea, when treating of E. pulverulenta, Sims,
