. 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. Western Larch 51 are globose, dark red, and shining. The leaves are pale green, filiform, triangu- lar, rounded above, keeled below, i to 2.5 cm. long, numerous in each cluster, terminating branchlets about 4 mm. long; they fall off in the autumn. The staminate flowers are sessile, subglobose, and light yellow; the pistillate flowers are borne on the lateral branchlets of the previous year, are short-stalked, oblong, and reddish. The cones, which are borne on short, stout branchlets, are ovoid, blunt, 12 to 20 mm. long, light brown, shedding their' seed during the autumn and early winter, and fall off the next spring and summer; the scales are nearly orbicular, slightly longer than wide, concave, slightly irregularly toothed or entire; those near the middle of the cone are the largest, those towards each end smaller; the bracts are about half the length of the scales and abruptly tipped; the brown seed is about 3 mm. long, one third the length of its wing. The wood is hard, strong, compact but coarse-grained, Ught brown, and durable; its specific gravity is about 0.62. It is largely used in ship-building; also for telegraph poles and railroad ties. The bark and the resinous exudation therefrom are reputed to be of some medicinal value. As an ornamental tree it is the most desirable of the Larches for planting in the northern States, growing very rapidly and retaining its symmetry of form longer than any other. The Alaska larch, Larix alaskensis W. F. Wight, very recently described, is said to differ from the Tamarack by shorter leaves, relatively longer cone- scales, and bracts not abruptly tipped.. Fig. 39.— Tamarack. '2. WESTERN LARCH — Larix occidentalis Nuttall This, the largest known species of its genus, is also called Red American larch. Great Western larch, and Western tamarack. It
