This plant is one of tlie very most frequent and characteristic ones in the Urjan- 

 kai country and in the frontier regions of Siberia. It is especially frequent over tracts 

 previously ravaged by forest fires, where it is one of the very first plants immi- 

 grating, constituting within a short time a nearly impenetrable growth, to over a man's 

 height. Thus it may be seen to cover, nearly sole prevailing, large stretches to seve- 

 ral square miles wide, giving the scenery in the flowering season, in July and August, a 

 purple appearance. Besides the common form with red flowers, I have also collected 

 specimens with white petals, /. albiflorum. 



Distribution: Throughout Europe and Asia, southwards to tlie East Indies, Sakhahn, 

 rare in eastern Asia, North America, southwards roughly to California.
