berley Division (technically termed the Northern Division) 

 and the area joining the two. We thus have the continu- 

 ous coastal tropical districts of Western Australia as far 

 as their junction with the Northern Territory, into which 

 the western State insensibly merges, and there is no line 

 of botanical separation between them. Indeed, the flora of 

 the Nor- West cannot usefully be studied without taking 

 cognizance of that of the coastal tropical portion of the 

 Northern Territory. When more local floras have been 

 worked out, we shall be able to construct botanical pro- 

 vinces irrespective of the political divisions. In the "Flora 

 Australiensis" and Mueller's "Census," the Nor-West is 

 sunk in the general term of North Australia. 



So that we have three different Nor- Wests: — 



a. Of local land administration. 



b. From the DeGrey to the Murchison. 



c. The Nor-West in its wide sense. 



Jutson styles the Kimberley Division the Kimberley 

 Peneplain, (op. cit., p. 33) contrasts it with the Eastern 

 Division just to the south, and his remarks are well 

 worthy of preference. 



The only list of Western Australian plants known to me 

 is based on Mueller's "Second Census of Australian Plants" 

 (1889); it is Mueller and Morrison's "List of Extra-tropic 

 West Australian plants" (Vasculares), in the "W. A. Year- 

 book for 1900-1," by Malcolm A. O. Fraser, Vol. i, p. 308. 

 This list is based on Mueller's compilation for the 1896 

 Yearbook ; Dr. Morrison, then Government Botanist of 

 Western Australia, made a number of additions, and says 

 (p. 308, foot-note):— 



"...those recently recorded from within the tropical line have 

 not been excluded from the present list, in spite of the wording 

 of the\ title; and it is hoped that the next edition will form 

 a complete'census of the native plants of the State, including also
