Tjiis species resembles the preceding very much in habit and in its 

 nowers, it appears however to be sufficiently distinct ; Mr. Nuttall re- 

 marks that It is alv/ays smaller, the leaves invariably smftoth jand rather 

 Jiiick, while the rest of the jilant is covered with a viscid pubescence, and 

 ttiat the teeth of the calyx are conspicuously awned. 



Grows like the preceeding in dry soils, more common in the middle 

 and upper country of Carolina than along the sea coasts. 



Flowers July— September.
