I have cones of different sizes of this Pine, and I think ther6 

 exist several varieties of it.

 hardly exceeding a foot in diameter ; dry ridges and slopes at an

 P. inops var. clausa, Chapman. 



Habitat. — Florida, shores of Pensacola Bay, south, generally within 

 30 miles of the coast, to Pease Creek, and occupying a narrow ridge 

 along the east coast south of St. Augustine. 



A tree 70-80 feet in height, with a trunk 2-2^ feet in diameter, or 

 on the west coast rarely 20-30 feet in height ; barren, sandy dunes 

 and ridges ; most common, and reaching its greatest development, 

 about the head of Halifax Bay. 



Wood light, soft, not strong, brittle ; bands of small summer cells 

 broad, very resinous, conspicuous, resin passages numerous, prominent; 

 medullary rays numerous, thin ; colour light orange or yellow, the thick 

 sapwood nearly white ; specific gravity, 0*5576 ; ash, 0"31 ; occasionally 

 used for the masts of small vessels (C. S. Sargent). 



This species m.ay not yet be introduced into the northern parts 

 of Europe. I possess typical cones of it in my collection.
