6. Gregory, F. T. " Expedition to the North West Coast 

 of Australia." (Proc. Roy. Geog. Soc. 1862, p. 372, with 

 a map). At p. 373, " Mr. P. (Pemberton) Walcott joined as 

 a volunteer for the collection of specimens of natural history 

 and botany." There are a few botanical notes at pages 

 377, 382, 385, 389, 428. The plants collected are recorded 

 in the "Flora Australiensis" as "F. Gregory's Expedition"; 

 Walcott's name was probably not given to Bentham. For a 

 note on Walcott see my "Records of W.A. Botanists." 



Bentham records that Maitland Brown also collected 

 specimens in this expedition. See a brief note in the 

 Records just quoted. See also "A record of the plants 

 collected by Mr. Pemberton Walcott and Mr. Maitland 

 Brown in the year 1861, during Mr. Gregory's Exploratory 

 Expedition into North West Australia," by Ferd. Mueller, 

 Trans. Bot. Soc. Edin., vol. n, pp. 479-500 (Paper read 

 February 1863). 



See "W. A. Year-book, 1900-1," Vol. I. At page 57 is a 

 brief account of F. Gregory's results, and the whole chapter 

 on "Exploration in Western Australia," beginning at p. 50, 

 is valuable. The chapter should be read for a statement 

 of Nor- West explorations. 



A useful account of Tropical West Australian explora- 

 tions will be found at p. 16 of A. Despeissis' "The Nor- 

 West and Tropical North," being Bulletin No. 13 of the 

 Department of Agriculture, W.A. (1911). Mr. Despeissis 

 refers to Mr. F. T. Gregory's report as the "origin and 

 foundation " of Nor- West settlement, so that special atten- 

 tion to the district has only taken place within the last 

 half-century, and its comparative inaccessibility, and the 

 moisture-laden atmosphere of a portion of it, both explain 

 the delay which has occurred in working out the plants.
