or the felt can be more loose and tufted. Besides this, the seasons 

 can influence the hairiness, the earliest shoots in spring often being 

 more densely felted than those developed later. 



The inflorescence; the number and size of the heads (capitula). 



The colour of the involucre is generally darkly olive-brownish, but 

 sometimes it can be more reddish. I have however never seen 

 such light reddish-brown colours as are apparently common in 

 Scandinavian specimens. 



A var. Frieseana Trautv. (Syn. A. monocephala DC.) is most fre- 

 quently mentioned in the literature, and differs by the absence of runners,

by having single flower heads and dark brown involucres. It is especially 

 common in East-Siberia, where, according to Kjellman, it is connected 

 with the main species through numerous transition forms. It is also 

 found in America and in Greenland, where apparently it is not rare. 

 According to the above mentioned distinct characteristics it should form 

 a transition to the following species. However, I do not believe such 

 is the case, as I have never seen it growing in ]шге groups of common 

 origin, so typical of A. glabrata.
