_ A small tree, rarely attaining the height of 30 or 40 feet, and 12—15 

 inches in diameter, with scattered, tough, flexible and smooth branches. 

 Leaves, as m all of the genus linear, acute, 1—2 inches long, united in pairs 

 meach seath. Cone ovate, about 2 inches long; spines near the summit 

 ot the scales subulate, straight, acute. 



This is a scrubby species of pine, and its wood is said to be of little value. 

 It IS said by Pursh to grow in Carolina; and it is probably one of the 2-leav- 

 ed species desciibed by Walter. I have, however, never seen it in the low 

 country of Carolina or Georgia, 



Grows in dry gravelly soils.
