 t. 293. Open woods, &c, upper country of Alabama and Carolina 

 along the Alleghanies to Huntingdon Co., Penn. f Porter. — P. ovata 

 is the earlier name (although rendered somewhat obscure by the char. 

 " floribus solitariis," which was taken from Plukenet's figure), and is 

 the more to be preferred as the original of P. Carolina is one of those 

 forms which seem to pass gradually into P. glaberrima. The Carolin- 

 ian specimens of " Gray and Carey," referred in the Prodromus to 

 P. glaberrima, are clearly of the present species.
