Pinus koraiensis
Korean pine
An evergreen coniferous tree, capable of reaching 30m (100ft) high with a trunk 1.5m (5ft) in diameter, when mature. The bark is smooth and grey-brown becoming grey-black and peeling in patches over time. The tree forms a broadly conical canopy, with the needles produced in groups of five at the tips of short stems. The needles are approximately 13cm (5in) long and triangular in cross section, being dark green on the outer face and whitish green on the two inner faces. The cones appear in groups of up to 5 and are oval to cylindrical in shape and brown in colour when mature. The cones of this species are one of the main sources of pine nuts which are harvested for commercial use.
