Abies magnifica

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 1,400–2,700 metres (4,600–8,900 ft) elevation, though only rarely reaching tree line. The name red fir derives from the bark color of old trees.

Description edit

Abies magnifica is a large evergreen tree typically up to 40–60 metres (130–200 ft) tall and 2 m (6 ft 7 in) trunk diameter, rarely to 76.5 m (251 ft) tall and 3 m (9 ft 10 in) 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, 2–3.5 centimetres (341+12 in) 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, 9–21 cm (3+128+14 in) long, yellow-green (occasionally purple), ripening brown and disintegrating to release the winged seeds in fall.

 
Abies magnifica: Cones stand upright on branches.
 
Abies magnifica: Needle-like leaves bend upward.

Varieties edit

There are two, perhaps three varieties:

  • Abies magnifica var. magnifica, red fir – cones 14–21 cm (5+128+14 in) long, bract scales short, not visible on the closed cones. Most of the species' range, primarily in the Sierra Nevada.
  • Abies magnifica var. shastensis, Shasta red fir – cones 14–21 cm (5+128+14 in) long, bract scales longer, visible on the closed cone; bark 10–15 cm (4–6 in) thick. The northwest of the species' range, in southwest Oregon and Shasta, Siskiyou[2] and Trinity Counties in northwest California.
  • A. magnifica on the eastern slopes of southern Sierra Nevada – possibly a third variety, have not been formally named, also having long bracts, and additionally have smaller cones, 9–15 cm (3+12–6 in) long.

Related edit

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;[2] some botanists treat the former as a natural hybrid between red and noble fir.

First recording edit

This tree was first recorded by William Lobb on his expedition to California of 1849–1853, having been overlooked previously by David Douglas.[3]

Uses edit

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.[2]
