Flowering Piants and Ferns from North-Western Greenland. 31 



is found here and there; it is the same form as occurs on the arctic Euro- 

 pean islands. Together with it the form having the leaves hairy also 

 on the iipper side, var. argentea Blytt, has been found, and this variety 

 reaches farther north and also west, namely to the N. W. coast at Ingle- 

 field Land and to Wolstenholme Sound. 



At the present time I think we may include these forms with D. 

 octopetala and suppose them immigrated to Greenland from Arctic 

 Europe; but further studies may clear up the different Dnjas-iorms 

 and their geographical ranges better. It seems to me as if the Rocky 

 Mountains — Alaska form of D. octopetala ofwhich I have seen an ample 

 material in North American herbaria and also found myself in the Cana- 

 dian Rockies, is different from the eurasiatic true D. octopetala and 

 ought to be considered a separate species. If this is so the eastern origin 

 of the North Greenland D. octopetala becomes clearer.
