. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. 32 The Pines dark yellow to nearly black, and roughened with the pepistent bases of the bud- scales; branch-buds broadly ovoid, 8 to 12 mm. long, tapering upward to a sharp tip. The leaves are in sheathed fascicles of 3, seldom in 4's, glaucous green, to cm. long, closely and minutely toothed, the tip stiff; they have many rows of deep stomata on all 3 faces and contain 5 to 7 unequal resin- ducts, some of which are in the inner tissue, and 2 fibrovascular bundles. They persist for three or four years. The staminate flowers are in crowded clusters, oblong-cyhndric, to 2 cm. long, their anthers dark reddish- yellow. The pistillate flowers are lateral, in pairs or clusters, short-stalked, ovoid-oblong, their scales gradually tapering to a slender tip. The cones are hori- zontal or slightly drooping, ovoid or globular-ovoid, 4 to 6 cm. long, hght yellowish brown, and remain closed for several years before dropping the seed, after which they still persist for two or three years more; the scales are rounded at the apex and thickened by a dark oblong knob, terminated by a slender, incurved, usually deciduous prickle; seed about 3 mm. long, nearly black, often ridged and usually roughened; wing thin and very deh- cate, striped and shining, narrowly oblong, about 18 mm. long, 3 to 5 mm. wide; cotyledons 4 to 6. The wood is soft, brittle, coarse-grained, dark orange-colored, very resinous; its specific gravity is about ; it is sometimes used for masts and for construc- tion timbers, and occasionally sawed into lumber. The tree is locally tapped for turpentine. It is also known as Loblolly pine, Marsh pine, Bull pine,-Black pine. Bastard pine, Meadow pine, and Spruce Pond Pine. 24.
