The species of the subfamily Laricoideae are evergreen or deciduous trees that can reach the greater heights in the Pinaceae family (over 100 meters with Pseudotsuga menziesii var. menziesii [2]). The leaves are needle-like [ 1 ] and have primary stomatal bands only on the abaxial surface (below the phloem vessels).
Larix lyallii, the subalpine larch, or simply alpine larch, is a deciduous, coniferous tree native to northwestern North America. It lives at high altitudes, from 1,500 to 2,900 meters (4,900 to 9,500 ft), [3] in the Rocky Mountains of Idaho, Montana, British Columbia, and Alberta. There is a disjunct population in the Cascade Range of Washington.
