Root perennial. Stem one to two feet high, slightly furrowed, pubescent, 

 •with the hairs expanding. Leaves of the root sometimes deeply sinuate, 

 the upper leaves becoming gradually entire, all amplexicaule. Flowers m a 

 loose corymb. Involucrum many leaved; leaves subulate, nearly equal, 

 arranged nearly in two series. Florets of the ray very numerous, (one to 

 two hundred) pale purple, slightly two-cleft at the summit; stamens none; 

 style longer than the tube, two-cleft: of the disk very numerous, yellow, 

 five-cleft at the summit; stamens and style about as long as the corolla. 

 5fee(/ oblong, hispid; pappus pilose, under a lens scabrous. ^ ^ 



The exterior pappus is very inconspicuous if not entirely wanting in this 

 species; the florets of the ray have the interior pappus. This is scarcely 

 the E. Philadelphicum of Linnaeus. 



Grows very common in pastures and fields. 



Flowers February — June.
