Douglas-fir

Douglas-fir is the English name applied in common to evergreen coniferous trees of the genus Pseudotsuga in the family Pinaceae.
== Summary ==
There are five species, two in western North America, one in Mexico, and two in eastern Asia. The Douglas-firs gave 19th century botanists problems due to their similarity to various other conifers better known at the time; they have at times been classified in Pinus, Picea, Abies, Tsuga, and even Sequoia. Because of its distinctive cones, Douglas-firs were finally placed in the new genus Pseudotsuga (meaning "false Tsuga") by the French botanist Carrière in 1867. The genus name has also been hyphenated as Pseudo-tsuga.Wikipedia
Douglas firs were common on Reach, likely transplanted to the Earth colony by UNSC terraforming teams during its colonization.Halo: First Strike, page 27
