This plant is found native by the borders of the meadows m 

 Europe, from whence it was early introduced into the United States. 

 It was at first extensively cultivated in our gardens, but after a little 

 while became naturalized to our climate and can be procured in any 

 quantities from the woods and neglected fields ; and so much better 

 when wild, as to render care unnecessary with regard to its growth. 

 It is a perennial herbaceous plant, about two and a half feet in height, 

 with strong erect stems, branching towards the summit, of a reddish 

 color ; approaching a six sided shape and marked with fine parallel 

 lines. The leaves are simple, deeply parted, double, the divisions 

 being notched. The flowers which are in bloom from July to Sep-

 appearance from the manner in which they are grouped, springing 

 as they do from flower stalks of different heights branching from a 

 common stem, and forming a flat top. Each separate flower is a 

 compound composed of numerous florets of which those constituting 

 the disk are perfect and five cleft ; and those of the ray or margin
