The Douglas fir (Pseudotsuga menziesii)[3] is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir,[4]Douglas spruce,[5]Oregon pine,[6] and Columbian pine.[7] There are three varieties: coast Douglas-fir (P. menziesii var. menziesii), Rocky Mountain Douglas-fir (P. menziesii var. glauca) and Mexican Douglas-fir (P. menziesii var. lindleyana).[8]
Despite its common names, it is not a true fir (genus Abies), spruce (genus Picea), or pine (genus Pinus). It is also not a hemlock; the genus name Pseudotsuga means "false hemlock".
