Notes to List above: Epilobium palustre has been found, 

 outside the Norsemen's area, at South Disko, whither it might very 

 well have been carried from South Greenland by the wind. 



Rubus chamæmorus mav perhaps also have been brought by 

 birds from Arctic N. America. 



R. saxalilis, which is common in Iceland and Norway, but 

 lacking in North America, can hardly have been introduced by 

 other means than b\' the Norsemen. 



Of the Hieraciiim species, two extend beyond the Norse area, 

 but as all are endemic (compare foot note on p. 18), and closely 

 related to European species (see also p. 35) I reckon them all 4 

 as old Norse piants. 



Zostera marina, only found in an inner arm of the Godthaab 

 Fjord, and fairly frequent in Icelandic, frequent in Norwegian 

 waters, and in America from the Strait of Belle Isle southwards, 

 I consider to have most probably been brought by a ship in some 

 way or other. Another supposition is that it is a survival from 

 the post-glacial heat period (see p. 47); its occurrence in the inner- 

 most part of the fjord, where the water is unusually warm, seems 

 rather to suggest this. 



Some further species might perhaps have been added or inter- 

 changed with those noted ; but the result would still be about 

 the same.
