A valuable review of the flora of South Australia as known at 

 that time. 



Hooker, in his introductory essay to the " Flora of Tasmania," 

 p. Iv., has a note " On the Flora of Countries around Spencer's Gulf." 

 He notes the western genera which find their eastern limits in South 

 Austraha, the tropical element, the absence or rarity of Proteacece 

 etc., and the prevalence of ComjoositcB, &c., as affording proofs of the 

 tropical and desert character of the South Australian flora.

 64 pp. From the " Handbook of South Australia." Government 

 Printer, Adelaide, 1875. 



This was the first flora of the province. He divides tlie country 

 into the scrub-land region, the grass-land region, the intra-tropical 

 region, and gives a list of the naturalised plants of South Australia. 



The list of species is mostly compiled from the " Flora Austra- 

 liensis," vols. I. -VI.
