Figure 61.Hemlock (Tsuga canadensis)
Abies canadensis Michx.
Hemlock spruce, weeping spruce, spruce pine, tanbark
The hemlock tree is found in forests from Ontario south to Virginia and Alabama and west to Michigan and Wisconsin.
This tall forest tree, which at times attains a height of 110 feet and a trunk diameter of 4 feet, is well known throughout its range as a source of tanbark. Its lower branches are somewhat drooping, and the dense, rather delicate foliage is deep green above and silvery beneath. The flat, narrow leaves are from one-half to three-fourths of an inch long and less than one-twelfth of an inch wide. The hanging cones are as long as or slightly longer than the leaves.
