Yunnan pine, Pinus yunnanensis, is found at lower elevations in Tibet, between 1,800 and 9,000 feet. The long, bright green needles can reach 1 foot in length and grow in clusters of two or three. The tree has a conical shape in youth that later matures into a flat-topped shape with a bare trunk.
Because of low winds in its native range, Yunnan pine can reach 80 feet in height. Its range overlaps with chir pine and Himalayan pine, making it a transitional species between the lowlands and upper plateaus. (info source: ehow.com)
