In East-Siberia the commonest form, but connected with 

 the main form b>' numerous transitions ; also found in Greenland 

 and America.

West-Greenland: between 64° and 72° 20'. 

 East-Greenland: between 66° and 72°. 



Not rare on Disco Island, although much rarer than the 

 preceding. Probably often overlooked, although it is very 

 conspicuous. Not found in the southernmost parts of Green- 

 land'bv collectors knowing the plant very well (Vahl, Rosenvinge, 

 Hartz, Kruuse).

 .4. dioica var. hyperborea Lange I.e. but probably not A. hyper- 

 horea Don: Edinburgh Philosophical Journal, i834, (a paper 

 not accessible to me), more probably— .4. hyperborea Fernald 

 & Sornborger: Some recent additions to the Flora of Labrador,

West-Greenland: 60° and 67°, commonest in the South. 

 East-Greenland: twice collected, at 61° and 66°. 

 Labrador? 



On Iceland neither is .4 . groenlandica, nor A . dioica nor 

 anv other of the nearest allies of this species found.

West-Greenland: hitherto only found a few times between 

 61° 45' and 70° OS'. On South Disco, near Godhaven, several 

 stations are known to me. The plant flowers here much later 

 than do A. alpina and A. glahrata on the same spots, whence I 

 suppose that it here is near its northern limit and should be 

 searched for in more southerlv latitudes.
