''Pinus squamata'', Qiaojia pine, zh: 巧家五针松) southern lacebark pine, is a critically endangered〔 pine native to a single locality consisting of about 20 trees in northeast Yunnan, China, at about elevation. The Qiaojia pine was discovered in April 1991 by Pangzhao J.Q. It was studied later that year and described the following year by Li Xiang-Wang. It shows similarities to Rzedowski's Pinyon and some other pinyon pines. ==Description== Its mature height is unknown because none of the living trees are yet mature, but they could possibly grow to or greater. Its habitat is open secondary woodland, scrub, and grassland mixed with Yunnan pine. The Qiaojia pine has a conic crown with flaky pale gray-green bark becoming dark brown with age, similar to the closely related Lacebark pine. The shoots are reddish to greenish brown and may be pubescent or glabrous. The leaves are drooping in fascicles of 4 or 5, long by wide, glossy green above with white stomatal bands on the underside. The cones are conic to ovoid, reddish brown, and long by broad when open. They open at maturity in September to October of the second year to release the oblong black seeds, long with a wing.〔Gymnoperm database (2008) (''Pinus squamata'' )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pinus squamata」の詳細全文を読む スポンサード リンク
