When we give the group of more or less ubiquitous species the 
largest possible range, so as to contain 90 species out of the 152, we 
find 73 of them in all the three districts here specially in question; 4 are 
absent from Ellesmereland, 13 from N. W. Greenland. The last number 
will, however, be considerably reduced by further research. If, on the 
other hand, we take the group of american species in its widest com- 
prehension, embracing 44 species, we get them thus grouped: in all three 
regions 23; in Ellesmereland and N. W. Greenland 7; in Ellesmereland 
and N. E. Greenland 2; in Ellesmereland alone 8; moreover 4 species 
not yet found in Ellesmereland but in N. W. Greenland (1) and as well 
in N. E. Greenland (8). 
These figures show clearly a gradual decrease of the number of 
american species to the east such as, a priori, we had to look out for; 
and the same is the case with the number of plants of decidedly ame- 
rican origin. Of these, Androsace septentrionalis, Chrysosplenium al- 
ternifolium, Alsine Rossii, and Carex membranopacta have only reached 
eastward to Ellesmereland. To these may be added Sawifraga Hir- 
culus, which may have reached N. E. Greenland from the east; Draba 
subcapitata, not yet known with certainty in Greenland; and Carex
