MARINE ALGAL VEGETATION 79 



Greenland is rather less, and to East Greenland is least of all, as 

 the following figures show: — 



common not common 



Iceland— Finmark 58 °/o 42 °/o 



Iceland — the Faeroes 55 °/o 45 °-/o 



Iceland— West Greenland 48 %> 52 % 



Iceland— East Greenland 39 ° o 61 % 



S. Iceland is too little known to be compared with other districts, 

 as has already been emphasized above. The resemblance to the 

 Fseroes will certainly prove to be much greater than is shown by 

 the figures now known. 



common not common 



S. Iceland — the Faeroes 44 % 56 °/o 



S. and SW. Iceland— the Fseroes . 55 °/o 45 °/o 



S. Iceland and SW. Iceland together resemble the Fseroes to the 

 same degree as do the coasts of Iceland taken as a whole. The fact 

 that S. Iceland least resembles the Faeroes is merely due to a de- 

 ficient knowledge of its coasts. 



As regards SW. Iceland — Finmark the percentage of species 

 common to both places is 56 and that of not common 44. Thus, 

 the resemblance is somewhat less than that between Iceland and 

 Finmark. 



If we now turn to E. Iceland we obtain the following figures : — 



common not common 



E. Iceland— West Greenland 58 °/o 42 °/o 



E. Iceland — East Greenland 53 °/o 47 % 



E. Iceland— White Sea 39 °/o 61 % 



E. Iceland has thus the greatest floristic resemblance to West 

 Greenland, resembles East Greenland somewhat less and the White 

 Sea least of all, although the floral districts of E. Iceland and the 

 White Sea resemble each other most closely when the species are 

 grouped according to geographical distribution (see above).
