Vol. I] STEWART— BOTANY OF COCOS ISLAND 381 



On comparing the above with the number of endemic spe- 

 cies found on the Galapagos Islands, one is at once struck with 

 the small number of endemic species found on this island ; and 

 while the entire flora is not recorded in this paper, it is very 

 likely that the number of species omitted is not large. It is of 

 course unsafe to draw any very definite conclusions from 

 incomplete data, yet it is safe to say that the per cent of 

 endemic species on the Galapagos Islands is very much larger 

 than on Cocos Island. It is interesting to note that but 8.69% 

 of the species mentioned in this paper are endemic, while in 

 the Galapagos Islands 40.9% are endemic. There is also an 

 evident wide divergence in the total number of species found 

 on the two, the Galapagos flora containing 682 species, while 

 the Cocas flora very likely contains but little if at all over a 

 hundred species. 



The wide divergence between the flora of the Galapagos 

 Islands and that of Cocos Island, has been mentioned by 

 authors who have written on these floras in the past. The 

 following is a list of the species found on Cocos Island which 

 are also found on the Galapagos Islands :
