Красная пихта Северной Америки (Krasnaya pikhta Severnoy Ameriki)

Species of tree found in North America

Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States. It is a high elevation tree, typically occurring at elevation, though only rarely reaching tree line. The name red fir derives from the bark color of old trees.

Abies magnifica is a large evergreen tree typically up to tall and trunk diameter, rarely to tall and diameter, with a narrow conic crown. The bark on young trees is smooth, grey, and has resin blisters, becoming orange red, rough and fissured on old trees. The leaves are needle like, long, glaucous blue green above and below with strong stomatal bands, and an acute tip. They are arranged spirally on the shoot, but twisted slightly S shaped to be upcurved above the shoot. The cones are erect, long, yellow green (occasionally purple), ripening brown and disintegrating to release the winged seeds in fall.

Red fir is very closely related to Abies procera (noble fir), which replaces it further north in the Cascade Range. They are best distinguished by the leaves; noble fir leaves have a groove along the midrib on the upper side, while red fir does not show this. Red fir also tends to have the leaves less closely packed, with the shoot bark visible between the leaves, whereas the shoot is largely hidden in noble fir. Shasta red fir hybridizes with noble fir, with which it is both chemically and microscopically similar;

The wood is used for general structural purposes and paper manufacture. It is also a popular Christmas tree. Paiute peoples used the foliage of Shasta red fir (or perhaps noble fir) to treat coughs and colds.
