Leaves abruptly narrowed and obtuse at apex, straight or slightly incurved, rounded and obscurely ridged and dark green and lustrous on the lower surface, flattened and conspicuously marked on the upper surface by 4 or 5 rows of stomata on each side of the prominent midrib, ¾′—1⅛′ long, 1/16′—1/10′ wide. Flowers: male dark purple; female oblong-cylindric, with obovate scales rounded above and reflexed on the entire margins, and oblong bracts laciniately divided at their rounded or acute apex. Fruit ellipsoidal, gradually narrowed from the middle to the ends, acute at apex, rather oblique at base, suspended on straight slender stalks, deep rich purple or green more or less tinged with purple when fully grown, becoming light orange-brown, 2′—4′ long, with thin broadly ovate flat scales longer than broad, rounded at apex, opening late in the autumn after the escape of the seeds, often becoming strongly reflexed and very flexible; usually remaining on the branches until their second winter; seeds acute at base, full and rounded on the sides, ⅛′ long, dark brown, and about one quarter the length of their wings broadest toward the full and rounded apex. A tree, usually 80°—100° high, with a trunk 2°—3° in diameter above the swelling of its enlarged and gradually tapering base, and furnished to the ground with crowded branches, those at the top of the tree short and slightly ascending, with comparatively short pendulous lateral branches, those lower on the tree horizontal or pendulous and clothed with slender flexible whip-like laterals often 7°—8° long and not more than ¼′ thick and furnished with numerous long thin lateral branchlets, their ultimate divisions slender, coated with fine pubescence persistent until their third season, bright red-brown during their first winter, gradually growing dark gray-brown. Winter-buds conic, light chestnut-brown, ¼′ long and ⅛′ thick. Bark ½′—¾′ thick, broken into long thin closely appressed scales dull red-brown on the surface. Wood heavy, soft, close-grained, light brown or nearly white, with thick hardly distinguishable sapwood. Distribution. Dry mountain ridges and peaks near the timber-line on both slopes of the Siskiyou Mountains on the boundary between California and Oregon, forming small groves at elevations of about 7000° above the sea; on a high peak west of Marble Mountain in Siskiyou County, California; on the coast ranges of southwestern Oregon at elevations of 4000°—5000°. 7.
