Varies greatly according to exposure and soil conditions. In the sterile, dry soil 

 of the pine barrens the pubescence is fine and close, the leaves narrowly lanceolate, 

 smoothish, and slightly denticulate. In the nu)iintains on shaded bonlers of woods 

 and in thickets of a richer soil forms prevail with the stem sparingly hairj' and the 

 intlorescence as well as the leaves viscidly hirsute, the latter more broadly sinuate 

 or repand-de.iticulate, agreeing closely with the type described by Willdenow. 

 (Specimens from Cullman County belong here.)
