yiew of an early isf^ue o£ a uew edition of tlie " Census,"" 

 which is necessitated by the large increase in the number of 

 species and consideral^le change in the species-nomenclature. 



The regional divisions adopted tentatively in my " Census " 

 as indicative of the lines of immigration of the constituents of 

 our flora may be subject to modification in accordance with the 

 meteorology and geology now somewhat better known. The 

 geographical demarcation of sub-botanic regions can only be 

 approximate, but for practical purposes a boundary line must 

 be drawn. The characteristics, physical and botanical, of each 

 division have to a large extent been gained by personal explor- 

 ation, but the botanical details can only be ascertained from 

 local observers working throughout the year. To such I make 

 an earnest appeal for help. Some portions of the colony have 

 not at all, or have been very imperfectly examined, or about 

 them more detailed information is wanting. Such are the 

 western portion of Kangaroo Island, south part of Yorke's 

 Peninsula, south and central parts of Eyre's Peninsula, the 

 country about the Coorong, the country towards the Grlenelg 

 Eiver, and generally the Par Xorth and West.
