GENUS TSUGA. 153 



Lindley ; A. Albertiana, Murray.) Alaska, British Columbia, 

 Oregon. 185 1. — Both as an ornamental tree and for its 

 rapid growth, this species can well hold its own with any 

 other that has yet been introduced. It is of erect growth 

 with a stout, leading shoot, that usually keeps well ahead of 

 the surrounding branches, the latter being long, lithe, and of 

 irregular lengths, while the branchlets are distinctly pendulous 

 and feathery. The foliage is two-ranked, and spreading hori- 

 zontally, or nearly so, each leaf \ an inch long, and of a dark 

 shade of green. Cones are plentifully produced in this 

 country, they resembling those of T. canadensis, but having 

 more elongated scales and longer wings to the seeds. 



The tree, when favourably situated, is of rapid upward 

 growth, the average of fifteen specimens that I measured being 

 15 inches per year. By far the finest specimen that I have 

 measured is growing amongst the Welsh hills at Hafodunos, 

 and which produced in thirty-five years 48^ feet of wood, or 

 fully 1 5 feet per annum. I have experimented with the timber 

 of twenty-five years' growth, and though it is hard, not heavy, 

 and of a pleasing light brown colour, yet the lasting properties 

 were not remarkable, but the partial immaturity of the wood 

 would to some extent account for this. This species is worthy 

 of trial for afforesting purposes.

 South California. — A distinct and ornamental small-growing 

 tree that is at once distinguished from any other species by 

 the nearly erect thickly scattered leaves, which are not two- 

 ranked and horizontally arranged as in most species. Each 

 leaf is I of an inch long, and either keeled and convex or 

 furrowed in the centre. The cones are about 2 inches long, 

 cylindrical-oblong, the scales becoming reflexed when quite 

 ripe or after the cones have fallen from the tree ; while the 

 beautiful lilac catkins are produced in such quantities as to 

 render the tree very conspicuous during early spring. 



In this country T. Pattoniana is of slow growth, but neat and
