description
The scaly bark grows as an evergreen tree that can reach heights of up to 40 meters and diameters of up to 1 meter at chest height . The trunk bark of old trees is divided into rough, square plates. The inner bark is red. Young trees and the branches of old trees have a bark that peels off in irregular, paper-like scales. The smooth or hairy twig bark is initially brown in young trees, from the second to third year it is brownish-gray in color.
The spherical winter buds are resinous. The straight or slightly curved, pointed or blunt needles are 1.5 to 3 centimeters long and around 2 millimeters wide. The top of the needle is dark green in color. There are two white stomatal bands on the underside of the needle . The needles are tightly packed in two rows on the branches.
The upright, short-cylindrical to almost oval cones are 5 to 8 inches long and 2.5 to 3.5 inches thick. When ripe, they are colored purple-brown. The winged, wide, wedge-shaped seeds are around 5 millimeters in size. The seed wing is about the same size as the seed.
