Distribution. Valley of the Chetco River, Oregon, 8 miles north of the California state line, southward near the coast to Monterey County, California; rarely found more than twenty or thirty miles from the coast, or beyond the influence of the ocean fogs, or over 3000° above the sea-level; often forming in northern California pure forests occupying the sides of ravines and the banks of streams; southward growing usually in small groves scattered among other trees; most abundant and of its largest size north of Cape Mendocino.
Often cultivated as an ornamental tree in the temperate countries of Europe, and occasionally in the southeastern United States.
2. [Sequoia gigantea] Decne. Big Tree.
Sequoia Wellingtonia Seem.
Leaves ovate and acuminate, or lanceolate, rounded and thickened on the lower surface, concave on the upper surface, marked by bands of stomata on both sides of the obscure midrib, rigid, sharp-pointed, decurrent below, spreading or closely appressed above the middle, ⅛′—¼′ or on leading shoots ½′ long. Flowers opening in late winter and early spring; male in great profusion over the whole tree, oblong-ovoid, with ovate acute or acuminate connectives; female with 25—40 pale yellow scales slightly keeled on the back and gradually narrowed into long slender points. Fruit maturing in the second year, ovoid-oblong, 2′—3½′ long, 1½′—2¼′ wide, dark reddish brown, the scales gradually thickened upward from the base to the slightly dilated apex, ¾′—1¼′ long, and ¼′—½′ wide, deeply pitted in the middle, often furnished with an elongated reflexed tip and on the upper side near the base with two or three large deciduous resin-glands; seeds linear-lanceolate, compressed, ⅛′—¼′ long, light brown, surrounded by laterally united wings broader than the body of the seed, apiculate at the apex, often very unequal.
A tree, at maturity usually about 275° high, with a trunk 20° in diameter near the ground, occasionally becoming 320° tall, with a trunk 35° in diameter, much enlarged and buttressed at base, fluted with broad low rounded ridges, in old age naked often for 150° with short thick horizontal branches, slender leading branchlets becoming after the disappearance of the leaves reddish brown more or less tinged with purple and covered with thin close or slightly scaly bark and naked buds. Bark 1°—2° thick, divided into rounded lobes 4°—5° wide, corresponding to the lobes of the trunk, separating into loose light cinnamon-red fibrous scales, the outer scales slightly tinged with purple. Wood very light, soft, not strong, brittle and coarse-grained, turning dark on exposure; manufactured into lumber and used for fencing, in construction, and for shingles.
Distribution. Western slopes of the Sierra Nevada of California, in an interrupted belt at elevations of 5000°—8400° above the level of the sea, from the middle fork of the American River to the head of Deer Creek just south of latitude 36°; north of King’s River in isolated groves, southward forming forests of considerable extent, and best developed on the north fork of the Tule River.
Universally cultivated as an ornamental tree in all the countries of western and southern Europe; and occasionally in the middle eastern United States.
