of Germany and Austria, as well as from Norway, Sweden, France 

 and Great Britain. Lindberg and Arnell report it further from 

 various localities in Siberia. For the most part it is alpine or sub- 

 alpine in its distribution although it sometimes descends to the sea 

 level in the northern part of its range. 



In North America its distribution is still very incompletely known. 

 According to the Synopsis Hepaticarum (1845) it was collected by 

 Vahl in Greenland, but there seem to be no other reports about its 

 occurrence on the island. In 1889 Underwood ^ showed that Pleuranthe 

 olivacea Tayl., which had been redescribed and figured by Sullivant 

 in the second edition of Gray's Manual (1856), was a synonym of 

 Harpanthus Flotowianvs. Taylor's species was based on material 

 in the Hooker herbarium, collected by J. Drummond in "North 

 America" and presumably coming from somewhere in western Canada. 

 In 1890 Pearson - cited the species vaguely from the "Rocky Moun- 

 tains (Bourgeau)," and Underwood, in his account of the Hepaticae 

 in the 6th edition of Gray's Manual, included H. Flotowianm, repro- 

 ducing Sullivant's figures of Pleuranthe olivacea. At the end of the 

 description the words "extra limital" appear, but Underwood^ 

 repudiated these two years later, stating that they had been added 

 without his knowledge and that he had reason to believe that the 

 species would be found in the northern United States. At the 

 same time he reported it from Labrador (Waghonie), the specimens 

 cited having come from Battle Harbor. In 1891 he had already 

 recorded the plant from British Columbia." This record was appar- 

 ently based on specimens in his herbarium collected by J. Macoun 

 in the "mountains of the Gold Range, north of Griffin Lake," in 

 August, 1889,^ although no statement to this effect is made. In 

 1900 the writer 6 detected the Harpanthus among the specimens 

 brought back by the Harriman Alaska Expedition and listed the 

 following stations: Hot Spring {T release), Orca {T release), Port Wells 

 (Trelease), and Yakutat {Breurr & Coe). In 1904 ^ he reported the
