cities, where it was for a year or two one of the most conspicuous 

 members of the flora on account of its abundance, it proceeded out 

 along the country roads in every direction, and fears were enter- 

 tained that it would become a noxious and abundant weed. After 

 a year or two of general abundance, however, it disappeared from 

 nearly everywhere except dumping grounds and waste places, 

 where it is still found in tolerable abundance. The type form of 

 virosa first appeared near the lake about 1908, and during that 

 and the following year was still confined to the railroad. This 

 plant has the compass-plant habit markedly developed, the major- 

 ity of the leaves turning on the edge and pointing roughly north 

 and south. Found north of the Barnes cottage, by Darnell's, by 

 Lakeview Hotel, and in numerous other places. Noted in flower 

 as late as October 30.
