He then makes the deduction — 



E. salmonophloia and E. oleosa being apparently the same tree in different forms of growth, it is 

 probable that the latter is a stage in the slow and permanent degeneration of the larger tree. 



In the Abstract of Proceedings of the Society, 3rd May, 1905, p. iv, Mr. Smith 

 also says : — 



From botanical and chemical evidence it is assumed that E. salmonophluia of Western Australia 

 and E. oleosa of New South Wales belong to the same species. 



Now all this is an interesting contribution to the data which are being 

 collected in regard to Eucalyptus affinities, and which I hope to bring together and 

 analyse in the final Part of this work, but E oleosa and E. salmonophloia are not 

 so closely related as Mr. Smith's statements would lead most people to think. 



I would point out that E. oleosa and E. salmonophloia have differences of an 

 important character. Some differences have been pointed out by Mueller, and 

 following are more or less important : — 





E. oleosa. 



E. salmonophloia. 



A variable species. 



Varies very little, so far as we know. 



Size 



Shrub or small tree. 



Large tree. 



Bark 



Rough on butt, sometimes very rough. 



Smooth. 



Timber 



Reddish-brown. 



Red, paler than E. oleosa. 



Juvenile leaves 



Usually broad, rarely narrow, but never 



Narrow lanceolate, shining on both 





as narrow as those of E. salmono- 



sides. 





phloia. Glaucous on both sides. 





Mature leaves 



Glaucous to glabrous. 



Narrower ■ than oleosa. Yellowish 



Buds , 



Anthers 



Usually with a far longer operculum 



than salmonophloia.. 

 Large, opening widely, but more at the 



front, than does salmonophloia. 



Gland at the back large. 



green. 



Large, opening widely to the base. 

 Gland at top small. A broader 

 anther than oleosa, nearer hemi- 







phloia than oleosa. 



Fruits 





Smaller and more flat-topped than 

 oleosa. 





2. With E. salubris, P.v.M. 



This is a smooth, green-barked, fluted tree shaped like a gigantic gimlet, and 

 quite different in appearance to any other Eucalypt that I have seen. The "egg-in- 

 egg-cup " buds of E. salubris resemble the appearance sometimes seen in E. oleosa. 



I will deal with affinities when I deal with E. salubris. 



3. With E. leptopoda, Benth. 



The nan*ow lanceolate foliage and the shape of the fruit of this species at 

 once separate it from E. oleosa. I will make further remarks when I describe 

 E. leptopoda. 



4. With E. deeipiens, Endl. 



Comparison of Plate 63, Part XIV, and Plate 65 of the present Part shows 

 that the similarity is not great. The leaves of E. deeipiens are broader as a rule,
