daisy-like heads, a handsome weed, flourishing for the most part 

 in dry, much compacted soils along pasture pathways and in 

 country barnyards where men and hogs and cattle are wont to 



travel or congregate. Cow-weed would he 

 a more appropriate name than dog-weed or 

 dog-fennel, for it grows best about those 

 spots where kine gather and ruminate. The 

 juice is acrid and often poisons the skin 

 when the plant is freely handled. Each 

 year it springs up and holds its own, star- 

 ring the margins of the pathways with the 

 yellow crowns and white rays. Scraping

 trampled many times by slow-moving cows, 

 though mud-bedaubed or broken in stem

Common in southern Indiana in old meadows, fields and along 

 roadsides, usually in poor dry upland soil; less frequent north- 

 ward. May-Oct. One of the most handsome and popular of our 

 Composite yet, where it gets a good start, one of the worst of weeds.
