Trees. 46 The Pines The tree, on account of its rapid growth, is very valuable in regions 6i shifting sand, as a binder of the soil. It is also known as Old field pine, Spruce pine, Scrub pine, and Florida spruce pine. 34. JERSEY PINE — Pinus virginiana Miller Pinus inops Alton This tree grows in poor rocky or sandy soil from southern New York to In- diana, southward to Georgia and Alabama, is very abundant in Maryland and Virginia, but reaches its largest size, 36 meters tall, with trunk diameter of i m., in southern Indiana. Its usual height is about 12 meters. The trunk is short, its branches long, spreading or pendulous, in remote whorls forming a broad rather flat-topped conic tree. The bark is up to 12 mm. thick, shaUowly fissured into flat plates with thin close dark brown scales on its surface. The slender twigs are tough and phable, smooth, purple, with a bluish bloom, finally becoming grayish brown, and roughened by the thickened bases of the bud-scales; branch-buds ovoid, 8 to 12 mm. long, sharp-pointed, their scales dark brown with dryish margins. The leaves are in sheathed fascicles of 2, deep green and shining, 4 to 7 cm. long, i mm. thick, rather* stout, soft, flexible and more or less twisted, finely toothed, sharply thick-tipped, marked by many rows of smaU stomata, usually containing 2 resin-ducts and 2 fibrovascu- lar bundles; they are very fragrant, rather closely dispersed on the twigs and persist for three or four years. The staminate flowers are crowded, oblong, about 10 mm. long, their anthers yellow-brown. The pistillate flowers are lateral, near the middle of young shoots, are long- stalked, subglobose, their scales ovate, slender-tipped, pale green with a reddish tinge. The cones are sessile, or nearly so, spreading, narrowly conic when closed, ovoid when open, 4 to 7 cm.
