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. microsperma, 

 A. Alcoquiana, and A. Jezoensis. 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 1 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 species, with somewhat pendent 

 symmetrically disposed branches and reddish brown shining 

 bark. The variety taxifolia is of smaller growth, with longer 

 darker green leaves ; and Stand ishiana has large glossy dark 

 green leaves distinctly silvery below. 



7. A. Canadensis. 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 long, with oblong rounded entire scales. An extremely 

 elegant hardy evergreen, flourishing well in damp situations. 

 North America. 



8. A. Albertiana, syn. A. Williamsdnii and A. Mertensiana 

 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. Hoolceriana bears that name in some 

 gardens. 



A. Brunoniana from North India, and A. Tsuga from Japan, 

 are allied species. 



9. A. Hookeriana, syn. A. Pattoniana 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 dense much-branched shrub.
