The seeds of this plant are an impurity of nearly all grass seeds 

 and are distributed with them; fruiting plants are mown with 

 the hay, baled with it, and shipped about the country, pass un- 

 harmed through the digestive tracts of the farm animals and are 

 returned to the land in uncomposted stable refuse, carefully spread 

 no wonder it is such a pervasive weed. 



Stems often tufted, one to three feet high, erect, slender, finely 

 grooved, nearly smooth, sometimes forking near the top but usually 

 simple, springing from a short, thick rootstock fringed with fibrous 

 rootlets. Root -leaves in a tufted mat about the base of the stem, 

 spatulate in outline, pinnatifid and irregularly toothed, tapering 

 to petioles ; stem-leaves narrowly oblong, sessile and clasping, 

 also cut and toothed. Heads single at the summit of the stalk, 

 about two inches broad, bearing twenty to thirty spreading, white 

 rays, slightly notched at their tips ; disk yellow and about a half- 

 inch broad ; rays and disk-florets both fertile ; involucre very 

 shallow and flat, its bracts with scarious margins and closely im- 

 bricated. Achenes grayish black, finely ribbed, without pappus.
