long. A talltree. North of California. Height,?. Introduced in 1831. 
There are only small plants in British gardens. 
A tree with the general appearance of A. Douglasi. Branches and branchlets 
tubercled. Buds ovate, acute, covered with resin. Leaves turned in every 
direction, resupinate from being twisted at the base, linear, mucronulate, in- 
curved ; silvery beneath, articulated with an elevated tubercle, very short, 
not more than 2in. long, rigid, rather sharp-pointed, and very soon falling off 
the dried specimens. Cones pendulous, cylindrical, 3in. long. Only a very 
few plants of A. Menziésii were raised in the Horticultural Society’s Garden 
in the year 1832; so that the species is at present extremely rare in this 
country. Readily propagated by cuttings.

The hemlock spruce, in Europe, is a most elegant tree, from the symme- 
trical disposition of its branches, which droop gracefully at their extremities, 
and its light, and yet tufted, foliage. When the tree is young, the branches 
are quite pendulous, and remarkably elegant. The rate of growth, in the 
climate of London, is rather slow ; but plants, in 10 years, will attain the 
height of 6 or 8 feet; and, in 20 years, of 15 or 20 feet. The wood of the hem- 
lock spruce is less valuable than that of any other of the large resinous trees 
of North Am:rica; but the bark is inestimable, in that country, for the pur-
