(1) Introduction. 



In view of the fact that a list of Victorian Eucalypts was pub- 

 lished as recently as 1908 in the Recording Census of the Victorian 

 Flora, by Professor A. E. Ewart, D.Sc, and issued by the Department 

 of Agriculture, it might perhaps be thought that a new list is rather 

 premature or scarcely needed. 



Since, however, working on this important genus for many years 

 now, it has always seemed strange to me, that Victoria should, in 

 proportion to its size, have such a small number of species credited 

 to it. This fact was especially brought home to me when collaborating 

 on the species some ten years ago, and I then decided to give this subject 

 some attention when opportunity occurred. 



It seems to me that this is now the fitting time, when the Associa- 

 tion has its meeting in Melbourne, to give my views on the subject, 

 and these I submit in this paper. I do not, however, claim that this 

 list is by any means a complete one of the Eucalypts of Victoria, for 

 I am confident that species yet remain to be recorded and new ones 

 to be described. 



The principal factor actuating me in bringing forward this list 

 is not a self-satisfaction of adding so many more species to the Vic- 

 torian Flora, but that, in these days of exact sciences, a list as nearly 

 , correct as possible should be available for workers in Eucalyptology, 

 and also to make known that there are far more representatives of the 

 genus in the State than was thought to be the case in the past. 



It is also of importance in the interests of the State's scientific 

 commercial enterprise, whether certain Eucalypts, which are in great 

 request for particular products, are to be found in Victoria. 



Just to give two instances : — The two species which yield the highest 

 class of medicinal oils in Australia have never yet been recorded for 

 Victoria, and yet they both occur in the State. Eucalyptus Smithii 

 and E. polybractea yield the finest pharmacopoeia oils of any Eucalyp- 

 tus, and although originally described from the parent State, yet they 

 nevertheless extend south well over the Murray River.
