peariag naked towards the summit.

Ppduncles 10 — 



lated, glabrous, the lower on petioles 1 — 3 inches long. 

 15 linos long. Calyx at first closely appressed. Petals rather longer 

 thae the calyx. Serrh smooth without a vestige of the style, globose, 

 with a slight longitudinal cicatrice. 



This species which I propose with hesitation, differs from the preceding 

 much in size, and appears to differ in the corolla and seed. It requires 

 however, to be further examined. 



Grows in ditches and wet places. Collected 12 miles from Savannah 

 on the Augusta road. St. John's Berkley. Dr. Macbride.
