 Harbour. " Canada," given for this species by Pursh, has not been confirmed. Newfound- 

 land has been more recently cited by Mr. H. Reeks, who visited that country as an 

 ornithologist in 1866-68, and seems to have made an interesting collection of plants. See 

 London Jour. Bot., IX, p. 16. It is doubtful, however, whether the plant has ever been 

 found in America east of the Eocky Mountains. Sir Joseph Hooker's Arctic table shows 

 its range over the Northern hemisphere as follows : — European Alps ; Asia to Altai, &c. ; 

 Eastern Asia; Arctic America; N. W. America. (Tab. Arct. PL, p. 283.)
