WOOLLY LARCH—Laiix Lyallii Parlatore This tree, also called LyaU's larch, Mountain larch, Larch, and Tamarack, is an alpine species, growing only near the timber-line of mountains between the altitudes of 1350 and 2400 meters, being known from Montana, Oregon and Wash- ington to Alberta and southern British Columbia; its maximum height is 25 meters, with a trunk diameter of Fig. 41. — Woolly Larch. The branches are usually very irregularly divided, in rather remote whorls, elongated, pendulous or the upper ascending, forming a very irregular head. The bark on old trees is to 2 cm. thick, shaUowly fissured into irregular plates composed of loose dark red scales; on younger trees it is thin, smooth, somewhat shining, and yellowish gray. The stout twigs are thickly coated with brown hairs, becoming smooth and nearly black after several years and armed with stout blunt branchlets to 2 cm. long. The winter buds are characterized by the white matted hairy margins of their scales. The four-sided leaves are slender, needle- hke, , to 4 cm. long, and hght green. The staminate flowers are oblong, short-stalked, and pale yellow. The pistillate flowers are ovoid-oblong to ovoid, yellowish green tinged with purple. The cones are short- stalked, oblong, to cm. long, 2 cm. thick, somewhat pointed at the apex, and fall off during the first winter; their numerous scales are thin, oblong to obovate, reddish or sometimes green, their margins toothed, and more or less fringed with hairs; when mature the scales spread widely from the stout hairy axis; the bracts are large and much exserted beyond the scales, long, slender- tipped and purphsh. The seed, which is shed during the first autumn, is ob- hquely oblong, 3 mm. long, half the length
