Distrib. Throughout the island of Yezo from Hakodate to the Ochotsk coast; the 

 island of Sakhalin; the eastern and southern portions of Manchuria and in Eastern Si- 

 beria. The plant has not yet been found in the main island of Japan. 



On the continent, a variety having glabrous leaves is more common and more widely 

 distributed throughout the entire extent of Siberia from the Ural regions to Kamtschat- 

 ka; and also in Dahuria, Manchuria and Saghalin.

 mous size, especially in swampy places in the woods. It is also found in Saghalin and 

 eastern Manchuria, and in Kamtschatka to the Aleutian Islands.

Hab. Kuriles, northern (ex Pallas). 



Distrib. In Japan the plant has been found only in the island of Yezo, where it 

 was collected by J. Small at Cape Romanzoff (45^° N. hit.), by Dr. Albrecht at Hako- 

 date, and by the writer in a sphagnous bog near Sapporo. The plant is very widely 

 distributed throughout the arctic and subarctic regions of the northern hemisphere. 

 It is noteworthy that this arctic plant descends further southward in the islands of 

 Japan (41°) than in any other portion of the north temperate zone. Next comes the 

 Atlantic coast of North America, where it descends as far south as 44°; in Europe, to 

 50° in alpine districts; in northwest America to 52°.

Distrib. Very common throughout the island of Yezo and also in the northern prov- 

 inces of the main island of Japan. It occurs also in Saghalin, Manchuria and Siberia, 

 from the Altai region to Kamtschatka. The plant is, however, most widely distributed 

 in the subarctic and temperate regions of North America.
