General: Douglas Fir (Pseudotsuga menziesii) is a coniferous (cone-bearing) tree with flat needles that radiate in all directions around the twigs. The cones are cylindrical with three-pointed bracts that emerge from between the cone scales.

In southern Nevada, Douglas Fir is a rare component of the montane vegetation in the Canadian (Pine-Fir Forest) life zone in the Virgin Range (south of Mesquite, Nevada). The Virgin Range is the only place in southern Nevada where this species can be found; it is, however, more common in the northern states and is one of the main species cut for lumber in the western U.S. This species can also be found along the south rim of the Grand Canyon over the edge below Grandview Point.

Family: Pine (Pinaceae).
