Tho more modern facies of tlie Eremian flora is sliown not only by the high 

 percentage of exotic species (twenty in the Larapintine flora ; whilst for the whole 

 Eremian flora in South Austi-alia I have stated it to be, writing in 1888,* lG-8, thus 

 indicating an increase in the northei'n area, as might be expected as we approach 

 their centres of dispersal), but also by the wide dispersal of a large number of them, 

 which thus evince a quality of acconnnodating tliemselves to a great variety of 

 climatic and other physical influences. 



The majority of the plants possessing burr-like, pungent, pointed or adhesive 

 fi'uits belong either to exotic species or to endemic species of exotic genera, and
