hicolor is usually more fibrous, although often enough the dif- 

 ference is but slight. 



Mueller (Eucalyptographia) un(Jer largiflorens, says: — E. 

 odorata is distinguished by 



1. The generally broader leaves. 



2. Simple axillary umbels. 



3. More elongated calyces tapering rather more gradually 

 into the stalklets. 



4. By longer buds. 



5. Larger anthersi. 



6. Longer fruits not contracted at the orifice. 



I would say that, as a rule, hicolor has shorter filaments, 

 blunter opercula and subcylindrical or ovoid fruits in con- 

 tradistinction to the large hemispherical fruits of odorata. It 

 prefers drier situations to E. hicolor. 



The ''Cooburn or Black Box'' is a tree that is often placed 

 under E. hicolor, but in my opinion its plac'e is with odorata. 

 ''Cooburn, Black Box; Ironbark Box, Bastard Ironbark.'' 

 This tree is referred to in the following passage: — "Coo- 

 burn, Black Box {Euc. largi-fioreus). Timber hard, tough, 

 and durable ; very lasting underground, of a red color. Used 

 for fencing, rough buildings, and sleep'ers. Hab., stony 

 ridges, scrub forests, N. & S. coast districts {sic). 100-120' 

 2-3'. Not very plentiful. N.S.W. Catal. Col. and Ind. Exh., 

 p. 199.) 



It has a hard, scaly black bark. 



It is referred to by Mr. R. H. Cambage {Proceedings Linn. 

 Soc, N.S.W., 1900, 716) when discussing! hybridization. 



It appears to be the "Ironbark Box or Bastard Iron- 

 bark" of Condobolin (B. H. Cambage) ; the Ironbark Box or 

 Bastard Ironbark of Nymagee (R. H. Cambage) ; the Cooburn 

 or Black Box of Karrabri (Forester McG-ee). It is a tree 

 which requires further investigation, the first work to be un- 

 dertaken being a list of localities which produce timbers 

 known as "Ironbark Box" or "Bastard Ironbark." 

 {h) With E. meUiodora, A. Cunn. 



The figure (Suppl. pi. xvii.) Mueller's "Plants of the Colony 

 of Victoria," labelled E. odorata, Behr. & Schlecht, is, in my 

 opinion, E. meUiodora, A. Cunn. The affinity of this species 

 to E. meUiodora has ali'eady been pointed out in the 

 "Eucalyptographia." E. meUiodora is sharply separated by 

 it? drooping habit and pale colored wood ; the thickened rim 

 round the ripening edge of the fruit is common in meUiodora, 

 though far more seldom seen in odorata. 

 (c) With E. leucoxylon, F. v. M. 

 E. odorata may be i^eadily confused with E. leucoxylon as -
