Description. — A branched, leafy perennial 2-8 ft. high ; leaves ob- 

 long to narrowly lanceolate, pointed, entire, or slightly serrate, firm, 

 often scabrous ; heads racemose, clustered ; ray flowers purplish. 



Distribution. — Common in low grounds, thickets or borders of 

 fields from New England to Wisconsin and Minnesota. An allied 

 species, A. paniculatus Lam., is much like A. salicifolius except that 

 the leaves are more pointed, serrate and less scabrous. It is a very 

 variable species, with distribution similar to that of A. multiflorus.
