most wretched-looking specimens. This is due to its being 
Spring-tender as a small plant. 
There are several Japanese species of somewhat recent in- 
troduction we may mention here: A. firma, A. microspérmu, 
A. Aleoquidna, and A. Jezoénsis. The hardiness of some of 
these species has not yet been proved. 
6. A. Dougldsii.—_This is a magnificent and very lofty tree 
in its native habitat, where it occasionally attains a height of 
300 feet. leaves flexible, spreading, in two ranks, flat, linear, 
scarcely pointed, bright glossy green above, and more or less 
glaucous beneath, from 1 to 14 inches long. Cones about 3 
inches long, with broad rounded scales and conspicuous pro- 
jecting deeply-toothed bracteoles. A native of North-western 
America, introduced about the year 1826. Unfortunately, this 
beautiful ornamental tree, though perfectly hardy, will not 
flourish in an exposed situation, or the immediate vicinity of 
the sea. It is a fast-growing specics, with somewhat pendent 
symmetrically disposed branches and reddish brown shining 
bark. The variety taxvifolia is of smaller growth, with longer 
darker green leaves; and Standishirtiuw has large glossy dark 
ereen leaves distinctly silvery below. 
7. A. Canadénsis. Hemlock Spruce.—This is a very distinct 
species and very beautiful as a small tree. In its native 
country it grows from 50 to 80 feet high, with slender 
pendulous branches. Leaves linear, flat, obtuse, about 6 lines 
long, dark green above, silvery beneath. Cones less than an 
inch Jong, with oblong rounded entire scales. An extremely 
elegant hardy evergreen, flourishing well in damp situations. 
North America. 
8. A. Albertina, syn. al. Williamson and A. Mertensirina 
of gardens.—This is very like the last, and is often confounded 
with it; but the leaves are shorter, slenderer, and the branches 
hairy. The true Mertensiana is said to be distinct, but we 
do not know it, though A. Hovkerianw bears that name in some 
gardens. 
A. Brunonidna from North India, and 4. Tsiiga from Japan, 
are allied species. 
9. al. Hookerina, syn. A. Puttoniane of gardens.— A very 
distinct tree of large size. In a young state it has somewhat 
the habit of a Juniper, the leaves being linear, mucronate and 
erect, of a pale slightly glaucous tint. It is a very hardy 
species, forming an erect deusc much-branched shrub.
