breadth at the widest part. Seeds about the size of those of the common 



spruce ; with the wing, -| in. long, and f in. broad. A pyramidal drooping- 



branched tree. Himalayas, in Kamaon and Sirmore. Height 50ft. Intro- 



duced in 1818. The tree has not yet flowered in England. 



Varieties. Dr. Royle observes that the leaves in his figure are much narrower 



than those of A. Smithidna in Wallich's figure; and that the plants may 



probably be different species or varieties. Judging from the leaves, the tree 



in the Horticultural Society's Garden appears to be Dr. Royle' s tree. 



The rate of growth of this tree in British gardens is almost as rapid as that 



of the common spruce, to which it bears a very close resemblance, but the 



leaves are longer and paler. It is readily propagated by cuttings, and abundance 



of seeds have lately been imported. Some doubts having been expressed as to 



whether this plant is the A. Smithidna of Wallich (see Bot. Reg. for 1841), 



but none as to its being the P. Khutrow of Royle, we have in this edition 



preferred the latter name. 



ii. Leaves flat, generally glaucous beneath^ imperfectly 1-rowed. 



D. Natives of North America.

Spec. Char., $c. Leaves flat, blunt, entire, pectinate, silvery beneath. Cones 

 ovate-oblong. Bracteas elongated, linear, 3-pointed. (D. Don.) Leaves 

 from I in. to lin. long. Cones from 3|in. to 4 in. long, and lin. to If in. 

 broad ; scales, without the bractea, li in. long, and the same broad ; with 

 the bractea, If in. in length. Seed, with the wing, -|in. long, and fin. 

 broad ; without the wing, in. long, and ^ in. broad. The seeds are about 

 the same size as those of Picea pectinata, but more oblong. Cotyledons, ?. 

 A tall tree. North-west coast of North America, in forests. Height 100 ft. 

 to 180ft. Introduced in 1826- It flowers in the climate of London in 

 May, and its cones are matured in the June or July of the following year. 



Varieties. Cones of different sizes, and somewhat different in the shape and 

 size of the scales, have been sent home by Hartweg and others ; because, 

 doubtless, this species of spruce is liable to vary as well as every other ; 

 and the slightest variation in any species of plant which is comparatively 

 rare is immediately constituted a named variety. Only one variety, that we 

 have heard of, deserves notice. 



A. D. 2 tajcifolia. Stem and side branches straight 

 Douglasz'z they are always, 

 when young, more or less in 

 a zigzag direction, though 

 they become eventually 

 straight. Leaves twice the 

 length of those of A. Dou- 

 glas^, and of a much deeper 

 green. Fig. 1932. is from a 

 specimen and a sketch re- 

 ceived from Mr. M'Nab, 

 showing the foliage and 

 manner of branching of A. 

 Douglass in the Caledonian 

 Horticultural Society's Gar- 

 den, and which corresponds 

 exactly with the trees of this 

 name in the Chiswick Garden 1932. A. D. <a
