Fir (Abies) is a genus of 48–55 species of evergreen coniferous tree in the family Pinaceae. It is found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar); Douglas-firs are not true firs, being of the genus Pseudotsuga.

All native species reach heights of 10–80 m (30–260 ft) tall and trunk diameters of 0.5–4 m (2–12 ft) when mature. Firs can be distinguished from other members of the pine family by their needle-like leaves, attached to the twig by a base that resembles a small suction cup; and by erect, cylindrical cones 5–25 cm (2–10 in) long that disintegrate at maturity to release the winged seeds. Identification of the species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the bract scales of the cones are long and exserted, or short and hidden inside the cone.

Famous quotes containing the word fir:

    I remember, I remember
    The fir trees dark and high;
    I used to think their slender tops
    Were close against the sky;
    It was a childish ignorance,
    But now ‘tis little joy
    To know I’m further off from Heaven
    Than when I was a boy.
    Thomas Hood (1799–1845)

    Below me trees unnumbered rise,
    Beautiful in various dyes:
    The gloomy pine, the poplar blue,
    The yellow beech, the sable yew,
    The slender fir that taper grows,
    The sturdy oak with broad-spread boughs.
    John Dyer (1699–1758)

    We had hardly got out of the streets of Bangor before I began to be exhilarated by the sight of the wild fir and spruce tops, and those of other primitive evergreens, peering through the mist in the horizon. It was like the sight and odor of cake to a schoolboy.
    Henry David Thoreau (1817–1862)
