NATIVE AMERICAN SPECIES OF PRUNUS. 58 
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 twigs glabrous, dark reddish brown, and marked 
with oval or round lenticels. 
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 localities the fruit is commonly

Fic. 3.—Outline map of the United States, showing the distribution of native American species of 
Prunus: Alleghaniensis, umbellata, gravesii, maritima, gracilis, and venulosa, 
yellowish. Dr. Hugh M. Niesler, writing from Taylor County, Ga., 
in 1860, says: 
_ The fruit is much smaller [than P. angustifolia] and exceedingly sour, its color 
yellowish red—the yellow predominating, but still a color which I have never seen 
approached very closely byany 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.
