gigantic stature, but also in regard to its symmetrical growth, 

 rich deep green incurved foliage, and large erect cones. In 

 young trees the rigid crowded spreading incurved leaves arc 

 linear, lenticular, rather thick, about 1^ inch long, obtuse 

 or slightly pointed, of a glaucous bluish green on both sides at 

 first, ultimately assuming a darker hue. Cones sessile, 6 to 9 

 inches long, with large reflexed acuminate bracts, and large 

 broad and entire scales. This was discovered and introduced 

 by Douglas. It is a native of Northern California, and appears 

 to be perfectly hardy in this country, where there are already 

 many handsome specimens of considerable size. 



14. A. Nordmanniana. A magnificent tree, contrasting 

 well with the last. It grows from 80 to 100 feet high, and is 

 of quite regular growth, but the branches are less stiff and 

 formal, and the foliage is of a dark very glossy green above and 

 silvery beneath. Leaves on young trees spreading in two 

 ranks, with a half-twist at the base, about an inch long, rigid, 

 linear, flat, and minutely bifid at the apex. Cones pedunculate, 

 4 to 6 inches long, with cordate-acuminate recurved bracts and 

 large entire scales. This beautiful hardy tree is a native of 

 the Crimea and other countries bordering the Black Sea. 



15. A. bracteata. A tall slender tree with rigid linear flat 

 distichous leaves from 2 to 3 inches long, bright glossy green 

 above, and glaucous beneath. Cones about 4 inches long, re- 

 markable for the large coriaceous 3-lobed and fringed bracts 

 which greatly exceed the scales. Unfortunately this handsome 

 species starts into growth so early in Spring that the young- 

 shoots are almost invariably injured by the late frosts, and 

 therefore, as we have so great a choice, this should be rejected. 

 It is a native of California. 



A. religidsa is a handsome though tender Mexican species. 



* * Species in which the bracts do not exceed the scales of 

 the cones. 



16. A. Pinsapo. A most magnificent species in the regu- 

 larity and symmetry of its habit, attaining a height of 50 to 70 

 feet. The branches are dense and rigid, and very densely 

 clothed with thick linear lenticular, mucronate leaves enlarged 

 at the base, from 6 to 10 lines long, and regularly disposed all 

 around the branches, and at right angles with them. The 

 foliage is of a yellowish green hue, with glaucous stripes. 

 Cones sessile, oval or oblong, 4 to 5 inches long ; scales broad,
