Pseudotsuga menziesii is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is known as Douglas fir,^[2] Douglas-fir,^[3] Oregon pine,^[4] and Columbian pine.^[5] There are two varieties: coast Douglas-fir (P. menziesii var. menziesii), and Rocky Mountain Douglas-fir (P. menziesii var. glauca).  The common name honors David Douglas, a Scottish botanist and collector who first reported the extraordinary nature and potential of the species. The common name is misleading since it is not a true fir, i.e., not a member of the genus Abies. For this reason the name is often written as Douglas-fir (a name also used for the genus Pseudotsuga as a whole).  The specific epithet menziesii is after Archibald Menzies, a Scottish physician and rival naturalist to David Douglas. Menzies first documented the tree on Vancouver Island in 1791. Colloquially, the species is also known simply as Doug fir^[5] or Douglas pine^[5] (although the latter common name may also refer to Pinus douglasiana).^[8] Other names for this tree have included Oregon pine,^[4] British Columbian pine,^[5] Puget Sound pine,^[5] Douglas spruce,^[5] false hemlock,^[4] red fir,^[4] or red pine^[4] (although again the latter may refer to a different tree species—Pinus resinosa).  One Coast Salish name for the tree, used in the Halkomelem language, is lá:yelhp.  From: https://en.wikipedia.org/wiki/Douglas_fir.
