SUNFLOWER FAMILY. 89 



The plant is a native perennial, growing from New 

 Brunswick to Ontario and south of the line, in damp 

 Th Pi w <>ods, especially on their borders and in land 

 recently cleared but not broken up. Its slender 

 branching stem is one and one-half to three and one-half 

 feet high, with opposite long-petioled leaves, broadly 

 ovate and with coarse, sharp teeth. There is a character- 

 istic mat of dark brown fibrous roots. The small flower 

 heads, one-quarter of an inch or less in diameter, are 

 white, and arranged in close compound clusters.
