elliptic, narrowly margined, 2 lines long. Confined to northern and central 

 Coast Ranges of southern Oregon and northern California. — Introduced 

 to Great Britain about 1848 by Hartweg. In the East it is probably not 

 hardy north of Virginia. It is a handsome tree with spreading branches 

 and yew-like dark green foliage. It holds the record as the tallest tree in 

 the world, at least so far as actual measurements have been made, one 

 specimen in Humboldt County, California, measuring 340 feet, according 

 to Sargent. Greater heights assigned to species of Eucah'ptus were 

 erroneous. It reproduces by seeds and by stump-sprouts, the latter numer- 

 ous and remarkably persistent, often producing merchantable lumber. 



Var. adpressa, Carr. (var. albo-spica, Hort.). Smaller tree with shorter 

 branches: leaves shorter and broader, slightly appressed; young leaves and 

 tips of branchlets creamy-white, glaucescent when older. 



Var. glauca, R. Smith. Blue Redwood. Foliage with a decidedly bluish 

 cast. 



2. S. gigantea, DC. (S. Washingtonia, Sudw. S. Wellingtonia, Seem. 

 Wellingtonia gigantea, Lindl. Washingtonia calif ornica, Winslow). Giant 

 Sequoia (California Big Tree). Fig. 57. Tree 150- 

 275, rarely to 325 feet high, with trunk 10-30 feet in 

 diameter; crown pyramidal on young trees, rounded 

 at summit or much broken in age; bark cinnamon- 

 red, 1-2 feet thick, divided into rounded ridges 4-5 

 feet wide, corresponding to the lobes of the buttressed 

 base and separating into loose fibrous scales; branches 

 pendulous, cord-like: leaves scale-like, 3^-H inch 

 long, sharp-pointed, adherent to the 

 stem which they thickly clothe, the tip 

 free: cone ovoid, 2-3^:^ inches long, 

 13^2~2 inches broad, opening only 

 slightly, maturing the second summer, 

 persistent; scales 25-45; seeds oblong 

 or somewhat ovate, wing-margined, 

 2} 2-3 lines long. Western slopes of 

 Sierra Nevada, California. — Introduced 

 in 1853 by Wm. Lobb to Great Britain. 

 In the East it is not reliably hardy 

 north of Philadelphia, although in 

 southern and western New York trees 

 have occasionally reached a fair size 

 and in the neighborhood of Boston have 

 survived ordinary winters for a number
