In corn-fields, a troublesome weed. 



Annual. June, July. 



Root tapering. Herb clotlicd with upright hoary hairs. Stem 

 round, branched, leafy, about a yard high. Leaves sessile, 

 joined at the base, linear-lanceolate. Ft. on upright stalks, 

 purple, witli blueish streaks, large and very handsome, however 

 odious in the sight of the farmer among his ripening corn. Cal. 

 very hairy, with long, narrow, smoother teeth, ui)right before 

 and after flowering. This genus has been, by many botanists, 

 united \\\\\\ Einlmis ; from which it is distinguislied chiefly by 

 tlie very hard and tougli calyx, and unthvided petals, whose 

 teeth moreover, when present, are ])eculiarly horny and sharp, 

 unbke those of any other phuits of tliis natural order ; but they 

 are wanting in our only liritish species. 



This weed sliouUl be eradicated hv hand before flowering.
