The tree is 15 to 20 feet high, forming a compact head; bark of 

 the trunk dark brown, separating into small appressed scales; 

 branches often somewhat spinescent, clothed with dark-brown bark, 

 that of the young twdgs glabrous, dark reddish brown, and marked 

 with oval or round lent ic els. 



The species (fig. 3)^ was originally described from "very dry, 

 sandy soils," in South Carolina and Georgia, and extends southward 

 in Florida to Tampa, and westward at least to the Apalachicola 

 River. In the coast region of eastern Florida it appears to have a 

 larger, more turgid, often more nearly globose stone than in the 

 western part of its range from which material has been seen, but 

 otherwise it does not differ. In some locahties the fruit is commonlv

yeUo'wish. Dr. Hugh M. Niesler, writing from Taylor County, Ga., 

 in 1860, says: 



The fruit is much smaller [than P. angustifoUa] and exceedingly sour, its color 

 yellowi.sh red — the yellow predominating, but still a color which I have never seen 

 approached very closely by any Chicasa plum. I have never seen the tree elsewhere 

 than along the streams and around the fields near Columbus. 



The fruit is occasionally gathered and used for preserves.
