That W, II, after subtracling the Norse piants, becomes 

 so poor in species, is explained by the faet that the northern 

 part of the Norse settlement "Eystri byggd" lay just inside 

 the Southern boundary of the district, and at any rate 

 10 of the 23 Norse piants are found only in that small 

 area, while the remaining portion ol" the district is nol 

 large in extent and has very little ice-free land. 



Table II also shows the abnndance of species on Disko 

 island. As already mrntioncd, a iinmbor of sonth(>rly species 

 are found in the southern part of Disko, but do not go 

 so far north on the mainland. The peculiar conditions 

 obtaining on the island have been touched on several 

 times by M. P. Pousii.n, from whose band a detailed descrip- 

 tion ol llie flora and vegetation of this island may be 

 looked for.'
