SUNFLOWER FAMILY. 89 
The plant is a native perennial, growing from New 
Brunswick to Ontario and south of the line, in damp 
The Plant woods, 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, anid arranged in close compound clusters.
