PROCEEDINGS OF SECTION D, 295 



Turmng now to the most recent desideratum of Eucalyptus oils — 

 that terpene constituent — phellandrene, so much in request for mineral 

 separation by the flotation process ; Victoria is particularly rich in 

 species yielding this commodity, but so far no definite list of these trees 

 has been given. This hiatus is now bridged over in this paper. 



Then again, as regards timbers, Victoria has some very remarkable 

 specimens of Eucalyptus, for species like E. Delegatensis and E. obliqua, 

 which are just now in request for furniture-making and interior deco- 

 ration of public and private buildings as a rival to the imported 

 Japanese oak, are also Victorian, and thus the State cabinet-timber 

 workers need not fall behind those of the sister States — New South 

 Wales and Tasmania. But these two by no means exhaust the cabinet 

 and commercial timbers of this southern State, a list of which is here 

 |fiven. 



Such facts as these and others given in the paper, in my opinion 

 justify, if any justification is necessary, the publication of this new 

 t'ensus of Victorian Eucalypts. 



Bentham, in his Flora Australiensis, 1866, recorded 31 species for 

 Victoria, and Mueller, in his last Census in 1889 gives 37, whilst the 

 Recording Census of Victorian Plants, 1908, makes the number 40. 

 These numbers T find too small, for in this Census, 70 species and 5 

 varieties, are listed 



These discrepancies in numbers have, no doubt, been caused by 

 the want of data in the past, but which are now in possession of more 

 recent workers in the field of Eucalyptology. In some instances 

 they may have been due to doubt as to whether certain forms are 

 "Varieties or species. 



In the case of Baron von Mueller, he probably had far more 

 correspondents in the other States than in Victoria, for we find that of 

 the species described by him as new, 27 are South Australian and 

 Northern Territory, 25 Western Australian, 23 Queensland, 14 New 

 South Wales, 2 Tasmanian, and only 11 Victorian. 



Since the publication (1902) of the collaboration {supra), I have 

 been keen on collecting data in this connexion, and the completion of 

 an investigation upon Tasmanian Eucalypts by myself and my col- 

 league, H. G. Smith, has enabled me to make comparisons with the 

 Eucalypts of that island and those of Victoria, New South Wales, 

 and, as a whole, the mainland. 



Naturally, this has been productive of points of observation that 

 otherwise would not occur to one working oii the mainland species alone. 

 For instance, it is noticeable that the most closely allied genus, Ango- 

 phora, has only one representative in Victoria, and the group of Euca- 

 lypts closely allied to these again — the Bloodwoods — has also only 

 one — E. corymbosa. Now, as both these occur just on the political 

 border but yet north of what might be regarded as a natural dividing 

 range of mountains, they might be regarded as practically absent.
