was a common weed of barnyards and hogyards but now it is rarely seen ; 

 when it is found there it is usually a common weed, because all stock avoid 

 it. It is found sometimes in waste places and cultivated fields.

1 Dr. F. W. Pennell, who has made a lifelong study of this family, has identified 

 nearly all of my specimens. His profound study of the family leads me to accept his 

 nomenclature throughout. I have used his keys to genera that occur in Indiana in a 

 condensed form, and I hereby wish to express grateful acknowledgement.
