Distrib. In Japan the plant has been found ouly in the island of Yezo, whei-e it 

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

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

 distributed throughout tlie arctic and subarctic I'egions of the northern hemisphere. 

 It is noteworth}' that this arctic plant descends further southward in the islands of 

 Japan (41°) than in any other portion of the noith temiJerate zone. ISText comes the 

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

 50" in alpine disti-icts; in northwest America to 52".
