The '''Red Fir''' or '''Silvertip fir''' (''Abies magnifica'') is a western [[North America]]n [[fir]], native to the [[mountain]]s of southwest [[Oregon]] and [[California]] in the [[United States]].
Red Fir. Tree, 200-250 ft.: trunk 6-10 ft. in diam.: lvs. quadrangular, bluntly pointed on sterile and acute on fertile branches: cones oblong-cylindrical, purplish brown, 6-9 in. long; bracts much shorter than the scales. Sierra Nevada of Calif.; gregarious and forming great forests. —Wood occasionally manufactured into lumber. Less hardy in the eastern states than A. nobilis.}}
It is a large [[evergreen]] [[tree]] typically up to 40-60 m tall and 2 m trunk diameter, rarely to 76 m tall and 3 m diameter, with a narrow conic crown. The [[bark]] on young trees is smooth, grey, and with [[resin]] blisters, becoming orange-red, rough and fissured on old trees. The [[leaf|leaves]] are needle-like, 2-3.5 cm long, glaucous blue-green above and below with strong [[stomata]]l bands, and an acute tip. They are arranged spirally on the shoot, but twisted slightly s-shaped to be upcurved above the shoot. The [[conifer cone|cones]] are erect, 9-21 cm long, yellow-green (occasionally purple), ripening brown and disintegrating to release the winged [[seed]]s in fall.

==Varieties==
==Varieties==
*Var. shastensis, of S. Ore. and N. Calif., cones somewhat smaller, with bracts as long as or longer than the scales.
There are two, perhaps three varieties{{wp}}:
* ''Abies magnifica'' var. ''magnifica'' ('''Red Fir''') - cones large (14-21 cm), cone bract scales short, not visible on the closed cones. Most of the species' range, primarily in the [[Sierra Nevada (U.S.)|Sierra Nevada]]{{wp}}.
* ''Abies magnifica'' var. ''shastensis'' ('''Shasta Red Fir''') - cones large (14-21 cm), cone bract scales longer, visible on the closed cone. The northwest of the species' range, in southwest Oregon and [[Shasta County, California|Shasta]], [[Siskiyou County, California|Siskiyou]] and [[Trinity County, California|Trinity]] Counties in northwest California{{wp}}.
* Trees on the eastern side of the southern Sierra Nevada also have long bracts, and additionally have smaller cones, 9-15 cm long. These trees, possibly a third variety, have not been formally named{{wp}}.
Red Fir is very closely related to [[Noble Fir]] (''Abies procera''), 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. Some botanists treat ''Abies magnifica'' var. ''shastensis'' as a natural hybrid between Red Fir and Noble Fir{{wp}}.
