The Chir Pine (Pinus roxburghii) named after William Roxburgh, is a pine native to the Himalaya. The range extends from northern Pakistan (North-West Frontier Province, Azad Kashmir), across northern India (Jammu and Kashmir, Himachal Pradesh, Uttaranchal, Sikkim) and Nepal to Bhutan. It generally occurs at lower altitudes than other pines in the Himalaya, from 500-2000 m, occasionally up to 2300 m. The other Himalayan pines are Blue Pine, Bhutan White Pine, Chinese White Pine, Chilgoza Pine and Sikang Pine.


Male conesIt is a large tree, reaching 30-50 m tall and with a trunk diameter of up to 2 m, exceptionally 3 m. The bark is red-brown, thick and deeply fissured at the base of the trunk, thinner and flaky in the upper crown. The leaves are needle-like, in fascicles of three, very slender, 20-35 cm long, and distinctly yellowish green. The cones are ovoid conic, 12-24 cm long and 5-8 cm broad at the base when closed, green at first, ripening glossy chestnut-brown when 24 months old. They open slowly over the next year or so, or after being heated by a forest fire, to release the seeds, opening to 9-18 cm broad. The seeds are 8-9 mm long, with a 40 mm wing, and are wind-dispersed.
