buxifoliiim from the Scotch Highlands; and in 1837 Hornemann 

 described the small plant of Greenland as V. Vitis-Idaea, var. 

 pumilum} Under this name the Greenland plant has since been 

 known to the Danish botanists, and it was described by Lange and 

 beautifully illustrated in Flora Danica (xvii. t. 2960). More recently 

 Lange has recognized in Labrador material the Greenland plant, but 

 at the same time he considered the American plants in the main 

 identical with the European : " Hovedformen i Nord-Amerika, Sibi- 

 rien, hele Kuropa.' 1 - 



Thus by different European authors the plant of Alaska and of 

 Labrador has been distinguished from the commoner form of the 

 plant in Europe and identified with var. pumilum of Greenland and 

 the local plant described by Hooker from the Scotch Highlands, 

 while by Loddiges as early as 1825 the American form was distin- 

 guished as var. minor. In a large series of American material the 

 writer has been unable to find any specimens which can be satisfac- 

 torily identified with the large-leaved plant of Europe. All the 

 American material agrees, however, with the Greenland and Alaska 

 plants and these are well represented by the plate of var. minor, 

 Loddiges. Under this name, then, the American plant should be 

 known. 



The more important bibliography of the dwarf small-leaved form 

 is as follows :
