Pinus monticola

Western White Pine (Pinus monticola; family Pinaceae) is a species of pine that occurs in the mountains of the western United States and Canada, specifically the Sierra Nevada, the Cascade Range, the Coast Range, and the northern Rocky Mountains. The tree extends down to sea level in many areas, particularly in Oregon and Washington. It is the state tree of Idaho, and is sometimes known as the Idaho Pine. Western White Pine is a large tree, regularly growing to 30-50 meter and exceptionally up to 70 meter tall. It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves (‘needles’) are in fascicles (bundles) of five, with a deciduous sheath. The needles are finely serrated, and 5-13 centimeter long. The cones are long and slender, 12-32 centimeter long and 3-4 centimeter broad (closed), opening to 5-8 centimeter broad; the scales are thin and flexible. The seeds are small, 4-7 millimeter long, and have a long slender wing 15-22 millimeter long.
