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 theisland. In 1889 Underwood! showed that Plewranthe 
olivacea Tayl., which had been redescribed and figured by Sullivant 
in the second edition of Gray’s Manual (1856), was a synonym of 
Harpanthus Flotowianus. 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. Flotowianus, 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 (Waghorne), the specimens 
cited having come from Battle Harbor. In 1891 he had already 
recorded the plant from British Columbia.4 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 ® detected the Harpanthus among the specimens 
brought back by the Harriman Alaska Expedition and listed the 
following stations: Hot Spring (Trelease), Orca (Trelease), Port Wells 
(Trelease), and Yakutat (Brewer & Coe). In 19047 he reported the
