VII. The Paucity of Species on the East Coast. 



That this paucity of species on the East Coast is more 

 particularly due to unfavourable external conditions seems 

 quite evident, when we look at the tables for the individual 

 districts: E. II and E. IV, which have but little ice-free 

 land and no deep fjords, are especially poor. The low 

 values are perhaps due in some degree to the faet that 

 these districts have been but inadequately explored; this, 

 however, I have endeavoured to make up for by "inter- 

 polating" — see p. 22 footnote, — some common species 

 not recorded from there, but which, being found both to 

 the north and south, and not particular in their choice of 

 habitat, may nevertheless be supposed to occur there. 



In contrast to these two poor districts we have E, III 

 (Angmagsalik) and E. V (Scoresby Sound) where conditions 

 are far more favourable; here, we find 181 and 169 species 

 respectively; and it must be borne in mind also that, on 

 the East Coast, we have not to reckon with the old Norse 

 element. Two European species found in the Angmagsalik 

 district are not known any where else in Greenland, viz: 

 Sedum acre and Alchimilla acutidens; these must be supposed 

 to have immigrated directly from Iceland, where they are 

 common. 



As regards Scoresby Sound, it is remarkable that some 

 species are found only on the inner branches of the fjord, 

 i. e. as far as possible from the rainy and misty coast with 

 the great belt of drift-ice outside. Two of these species are 



I
