142 PHANEROGAMIC FLORA’ OF SPITZBERGEN. 
D. octopetala, common in Greenland and Arctic America, is described, 
which is intermediate between that species and D. integrifolia, Vahl; 
these authors consider this latter species as only a variety of D. octo- 
etala. In the north of Spitzbergen this var. longifolia occurs very 
generally, and often in the same tuft with the normal form; but 
never found it with such entire leaves as the Greenland D. integrifolia, 
although they were often quite as narrow. I agree, nevertheless, in 
the opinion of Messrs. Regel and Tiling, that D. integrifolia is only a 
variety of D. octopetala, L., peculiar to Greenland and the mes 
of America.
