2. With E. viminalis Labill. 



Mr. L. G. Irby :".... thought at first it was E. viminalis from the abnormal (juvenile, 

 J.H.M.) leaves, but noted its differences in other respects from the normal material of that species collected 

 in other localities in Tasmania during his trip. An exhaustive oil determination, made since publishing 

 our Eesearch on the Eucalypts of Tasmania in Journ. Roy. Soc. (Tas.), 1912, confirmed our suspicion that 

 it was new. In that paper it was placed tentatively under E. viminalis. The chief specific differences 

 from this latter are the broader abnormal (juvenile, J.H.M.) and normal leaves, both of which are much 

 coarser than those of E. viminalis, and are always affected with a fungus, which is never so in E. Gunnn 

 or E. viminalis, and which gives the whole plant a black, dirty-looking appearance. This is evidently a 

 specific character bjr which it can be determined, just as in the case of E. camphora. The fruits are, however, 

 identical in shape with those of E. Gunnii." (Original description.) 



3. With E. Dalrympleana Maiden. 



(See above under No. 1, E. Gunnii). This species will be found described in 

 Part XLIX of this work. The foliage of E. Irbyi is glaucous, even dull-coloured.
