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, Douglas-fir, Oregon pine, and Columbian pine. Despite
its common name, it is not a true fir (i.e. it is not a member of the
genus Abies). 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).The massive mega-genome of Douglas fir was sequenced in
2017 by the large PineRefSeq consortium, revealing a specialized
photosynthetic apparatus in the light-harvesting complex genes.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). Douglas fir Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
