SAND PINE — Pinus clausa Chapman A tree of both coasts of Florida and the coast of southern Alabama, usually on sand dunes, and reaching a maximum height of 24 meters, with a trunk diameter of dm. The trunk is often clothed to the ground with spreading slender branches, forming a dense, sometimes flat-topped tree. The bark is about 10 mm. thick, deeply but narrowly fissured into irregular, oblong plates with close light reddish brown scales; on small stems it is thin, smooth, and gray. The twigs are slender, tough and pUable, smooth and yellowish green, becoming reddish brown and finally gray, and roughened by remnants of the bud-scales. The branch-buds are ob- long-cylindric, about 6 mm. long, with a rounded apex, the pointed brown scales shining and margined with pale green hairs. The leaves are in sheathed fascicles of 2, deep green, 4 to 9 cm. long, .75 mm. thick, very slender and flexible, minutely toothed, sharply short callous-tipped, marked with 10 to 20 rows of stomata and containing 2 resin-ducts, one of which is in the pulpy part of the leaf, and 2 fibrovascular bun- dles; they are rather Crowded and persist for three or four years. The staminate flowers are in elongated, crowded clusters, cylindric, 10 mm. long; their anthers are yellowish brown. The pistillate flowers are lateral, short-stalked, subglobose or oval, their scales ovate and long-pointed. The cones, maturing the second autumn, are short-stalked, usually clustered around the twig, conic when closed, ovoid when open, to 6 cm. long, mostly obUque at the base and dark reddish brown, sometimes opening at maturity, but usually remaining closed for three or four years, becoming hght gray; some remain closed and persist, becoming encased by the bark or wood growing around them. Their scales are conca
