Douglas Fir

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. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas fir. The massive mega-genome of Douglas fir has been sequenced in 2017 by the large PineRefSeq consortium revealing a specialized photosynthetic apparatus in the light harvesting complex genes.
