On road sides and in. newly cleared grounds : Canada to 
Carolina. ©. July, Aug. v. v. From two to five 
feet high. This is one of the plants which spring up 
in the most remote western countries, when the land 
is cleared of timber, particularly when the brush- 
wood is burnt on the ground ; from which circumstance 
it is generally known by the name of Fire-weed. I 
have frequently found it covering a square piece of 
cleared land, when there was not a single plant to be 
found in any other place for a considerable distance 
round it.
