western distribution on the preceding pages (29 — 32) the species occuring 

 on the north coast are marked by an asteric (*). Amongst the north 

 coast species \ve find of course mostly common and hardy high-arctic 

 species, but it is surprising to see that also such a less high-arctic spe- 

 cies as Erigeron uniflorus eriocephalus has been found. 



In the table II the number of species of the supposed different 

 distributions are given, both from the whole North-Greenland and 

 from the north coast alone. There is not much difference in the per- 

 centages; only the eastern species are fewer on the north coast, a rather 

 interesting faet to which I shall refer later on. 



Table II a. 



If we consider the three "endemic" species as really of western 

 origin, which is most probably as explained above, the table gets the 

 following figures: 



Table II b. 



These tables show that the western character of the flora of North- 

 Greenland is very marked; this is only what is to be expected. 



From the north coast southwards on the west coast of North- 

 Greenland we know — - as mentioned before — very little of the flora 

 of the area north of the Humboldt Glacier, but still it seems as if this 

 huge ice-mass is a barrier preventing the advancement northwards 

 of several species. The northern limit of the following species lies, at
