Varies greatly according to exposure and soil conditions. In the sterile, dry soil 
of the pine barrens the pubescence 1s fine and close, the leaves narrowly lanceolate, 
smoothish, and slightly denticulate. In the mountains on shaded borders of woods 
and in thickets of a richer soil forms prevail with the stem sparingly hairy and the 
inflorescence as well as the leaves viscidly hirsute, the latter more broadly sinuate 
or repand-deaticulate, agreeing closely with the type described by Willdenow.
