  1. Larix occidentalis

    Western Larch is a species of larch native to the mountains of western North America, in Canada in southeastern British Columbia and southwestern Alberta, and in the United States in eastern Washington, eastern Oregon, northern Idaho and western Montana. It is a large deciduous coniferous tree reaching 30–60 m tall, with a trunk up to 1.5 m diameter. The largest known Western larch is 153 ft. tall, 22 ft. in circumference, with 34 ft. crown, located at Seeley Lake, Mt. The crown is narrow conic; the main branches are level to upswept, with the side branches often drooping. The shoots are dimorphic, with growth divided into long shoots and bearing several buds, and short shoots only 1–2 mm long with only a single bud. The leaves are needle-like, light green, 2–5 cm long, and very slender; they turn bright yellow in the fall, leaving the pale orange-brown shoots bare until the next spring. The seed cones are ovoid-cylindric, 2–5 cm long, with 40-80 seed scales; each scale bearing an exserted 4–8 mm bract. The cones are red when immature, turning brown and the scales opening flat or reflexed to release the seeds when mature, 4–6 months after pollination. The old cones commonly remain on the tree for many years, turning dull gray-black.
