breadth at the widest part. Seeds about the size of those of the common 
spruce ; with the wing, Zin. long, and 2in. 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. Smithiana 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.

Spee. Char., §c. Leaves flat, blunt, entire, pectinate, silvery beneath. Cones

from Lin. to IL in. long. Cones from 32 in. to 4 in. long, and 12 in. to 12 in. 
broad ; scales, without the bractea, 12 in. long, and the same broad ; with 
the bractea, 13in. in length. Seed, with the wing, Zin. long, and 3 in. 
broad ; without the wing, 1in. long, and 3,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 180 ft. 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. 
2 A. D. 2 taxifolia.— Stem and side branches straight ; while in A. 
Douglas? 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- 
glisi, 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. 
Douglas# 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. taxifoha.
