Douglas fir / Pseudotsuga menziesii and Pseudotsuga macrocarpa
(see fact sheet for synonyms)
5" x 5" flat cut, 5" x 5" quartersawn, 3/4" wide end grain, and a 1/4" x 1/4" end grain closeup.
This softwood does have resin canals and rays are visible at 10X. Growth ring boundary are very obvious and the transition from light earlywood to a darker latewood is abrupt. Swirly face grain is common on flat cut. Plywood using rotary cut veneer face has very swirly and irregular grain.
NOTE: To be technically correct, the name of the wood is "Douglas-fir"; capitalized and with a hyphen. It is not used that way in common usage, so although "douglas fir" is incorrect, that is the way it is normally used. Also, these two species are NOT firs at all, nor are they spruce or pine ... they are "Douglas-fir (not actually a fir)" and nothing else thanks to the U.S. Forest Service.
A sampling of other English language common names: black fir, blue Douglas-fir, coast Douglas-fir, Colorado Douglas-fir, common Douglas-fir, cork-bark Douglas spruce, inland Douglas-fir, Oregon Douglas-fir, Rocky Mountain Douglas-fir, yellow Douglas-fir, Oregon pine, red pine, Oregon spruce, red spruce.
Pseudotsuga macrocarpa is generally called "big-cone Douglas-fir" or sometimes "bigcone spruce" (although it is not a spruce)
