This variable plant is very widely distributed throughout the subarctic and cool tem- 

 perate regions of the northern hemisphere. In Japan, however, the plant has not yet 

 been found in a wild state. A few plants were found around a new pasture ground in 

 Sapporo in 1880. It is highly probable that they had been introduced there mixed with 

 the seeds of grasses from America.
