Picea Dougiasn. va] q e fy (A. Smiihiana ), will apply. Plants 
with us, in low, damp ground, suffer occasionally in color, if 
not in loss of leader, while those grown in the shade, or on an 
exposed hill-side, in poor, slaty soil, succeed admirably. This 
is also the case near Boston, at “ Wellesley” (Mr. Hunne- 
well’s), where trees, two years planted, are five feet high, and 
do admirably in the shade ; while at Mr. Reid’s, at Elizabeth- 
town, it loses its leader in severe winters ; and near Phila- 
delphia, Mr. Meehan reports : “ that so far it has not been 
satisfactory.” At Washington, perfectly hardy ; at Newport, 
it wont stand; though at Augusta, Ga., and Cincinnati, it 
thrives well. The variety originates in the north-western 
part of North America, and along the banks of the Columbia 
River, where it is found in immense forests, and also on the 
Rocky Mountains, on the top of which, it rarely is more than 
a small bush, but becomes larger and more stately as it 
descends, until it reaches the altitude of one hundred and 
fifty to two hundred feet. Its foliage is very dark, and the 
tree generally resembles a superb balsam fir. 
A. Jezoensis (the Jezo fir), found in China, and the Island of

decidedly. It is quite striking. There has been 
a good deal of confusion in its classification, as to whether it is 
a spruce or Silver fir, and it would seem to be intermediate, 
though we believe with persistent cones. Our specimens, 
which are small, seem quite hardy, and are not very unlike in 
their general appearance, the Torreya , and also the Cephalo- 
taxus. 
Araucaria. 
This extraordinary and most distinguished genus of plants 
derives its name from Araucanos, a people of Chili, where the 
species known as imbricata greatly abounds, its seeds being 
used for food.
