I met with it first 



in 1895 by the Wabash railroad in Will county and agahi the past 

 season at Lake Zurich, Lake county, where it grows by roadsides 

 with Panicitm prolifennn and Sporobolus vaginacflorns, a frequent 

 grass in dry grounds and waste places wherc It generally grows 

 in dense patches. Both of them have a different habit when grow-

 stools with the much stouter stems semi -prostrate or ascending. 

 Paniciim prolifennn has a similar habit, becoming a good sized 

 weed in dry grounds, though smaller than in its native swamps or 

 wet lands. The three seem well adapted to endure the wear and 

 trampling to which such plants as grow by highways are more or* 

 less subjected.
