1891,] D. Frsiin— The Vegetation of the Coco Group. 387 



An analysis of the table of distribution from tlie opposite point of 

 view is given below ; from it we learn that 11 species, or 14 per cent., 

 are cosmopolitan on tropical sea-shores ; that four mox"e are nearly cos- 

 mopolitan, being present in both hemispheres ; that only four, so far as is 

 known, are limited to the coasts of these islands, the Andamans and the 

 Nicobars ; and that, excepting these four, every one of the species is found 

 on the Malayan Coasts. So far then as the " littoral " species are con- 

 cerned we must conclude that the flora of the Coco Group is decidedly 

 Malayan.

In discussing the inland "immigrant" species the first agency to 

 be considered ,is that of winds. This influence musb here be sti'onger
