The larch's tree crown is sparse and the branches are brought horizontal to the stem, even if some species have them characteristically pendulous. Larch shoots are dimorphic, with leaves borne singly on long shoots typically 10 to 50 cm (4 to 20 in) long [ 2 ] : 47 and bearing several buds , and in dense clusters of 20–50 needles on short ...

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.
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).
The Pinaceae (/ p ɪ ˈ n eɪ s iː ˌ iː,-s i ˌ aɪ /), or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces.
Pinus ponderosa is a large coniferous pine tree. The bark helps distinguish it from other species. Mature to overmature individuals have yellow to orange-red bark in broad to very broad plates with black crevices. [14] Younger trees have blackish-brown bark, [14] referred to as "blackjacks" by early
