This species resembles the preceding very much in habit and in its 
flowers, it appears however to be sufficiently distinct ; Mr. Nuttall re- 
marks that it is always smaller, the leaves invariably smooth and rather 
thick, while the rest of the plant is covered with a viscid pubescence, and 
that 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.
