glaucous ; leaves from short sheaths, scattered, short and rigid, flat on the inner 
face; cones solitary, conical-oblong, mostly reflexed, short-peduncled ; scales 
armed with a straight subulate rigid spine. — Dry sandy or gravelly ridges in

and is distinguished here, as in South Carolina, as the SPRUCE-PINE.
