Family: Pinacea
Genus: Pseudotsuga
The Douglas Fir is a native of north-western America and Canada. It is capable of growing to a great height. The species to which it is usually referred is (Pseudotsuga Menziesii), which has several varieties, and there are two or three other minor species.

The needles are flattened and grow all round the twig, attached by tiny stems (petiole), which leave a raised leaf scar when the needle falls. The bark is deeply fissured, often with an orangey tinge inside the line of the fissure. The cones have three-pronged bract protruding from the scales. It is grown in this country on fertile, well-drained sites, where it does well.

In converted timber the rings are a dark and lighter reddish brown. After drying out, the lighter coloured "summer wood" tends to shrink back, giving a the wood a "washboard" texture, particularly on fast-grown timber. Where sizes have been large enough, the logs were favoured for being rotary cut and manufactured into plywood.
