Picea
To the species and varieties described on pp. 121-3, Vol. III., the following should now be added:
P. alpestris (rock-loving). This resembles P. excelsa, but has the young shoots velvety, with stiffer, shorter, thicker leaves, about 1/2in. to 3/4in. long, and more distinctly four-angled. Swiss Alps.
P. Breweriana (Brewer's). l. five to twelve lines long, one-half to one line broad, rounded or slightly keeled above, stomatose beneath on each side the prominent midrib, obtuse. cones slender, 3in. long, with thin, entire scales. Branchlets long, drooping, whip-like, puberulous. h. 80ft. to 90ft. North California, 1886. This tree somewhat resembles P. excelsa. (G. C. n. s., xxv., pp. 497-8.) P. excelsa virgata (twiggy). This is identical with the form monstrosa. P. Parryana (Parry's). A synonym of P. pungens.
P. pungens. Rocky Mountain Blue Spruce. "White, glabrous branchlets, stouter [than those of P. Engelmanni], in old specimens somewhat flattened, spiny-pointed leaves, blue in young trees and in the young growth of old trees; the cones are much longer and paler [than in Engelmanni], the bark thick, crooked, and greyish; leaves of seedlings somewhat denticulate" (Engelmann). A tall tree. SYN. P. Parryana.
