Douglas-fir

Description:

Douglas-firs are medium-size to extremely large evergreen trees, 20–120 metres (70–390 ft) tall (although only Coast Douglas-firs reach such great height).[6] The leaves are flat, soft, linear, 2–4 centimetres (0.8–1.6 in) long, generally resembling those of the firs, occurring singly rather than in fascicles; they completely encircle the branches, which can be useful in recognizing the species. The female cones are pendulous, with persistent scales (unlike true firs), and are distinctive in having a long tridentine (three-pointed) bract that protrudes prominently above each scale (it resembles the back half of a mouse, with two feet and a tail).
