''Pinus armandii'' (family Pinaceae), the Armand pine or Chinese white pine, is a species of pine native to China, occurring from southern Shanxi west to southern Gansu and south to Yunnan, with outlying populations in Anhui. It grows at altitudes of 2200–3000 m in Taiwan, and it also extends a short distance into northern Burma. In Chinese it is known as "Mount Hua pine" (华山松). It grows at 1,000-3,300 m altitude, with the lower altitudes mainly in the northern part of the range. It is a tree reaching height, with a trunk up to in diameter. ==Description== 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. They are 8–20 cm long. The cones are 9–22 cm long and 6–8 cm broad, with stout, thick scales. The seeds are large, 10–16 mm long and have only a vestigial wing; they are dispersed by spotted nutcrackers. The cones mature in their second year, this is a juvenile female cone: ;Varieties The species has two or three varieties: *''Pinus armandii'' var. ''armandii''. All the range except for the populations below. *''Pinus armandii'' var. ''mastersiana''. Mountains of central Taiwan. *''Pinus armandii'' var. ''dabeshanensis''. The Dabie Mountains on the Anhui-Hubei border. Alternatively, this variety may be treated as a separate species, ''Pinus dabeshanensis'' ("Dabie mountains pine"). To add further confusion, ''Flora of China'' lists this as ''P. fenzeliana'' var. ''dabeshanensis''. IUCN has listed var. ''dabeshanensis'' (assessed as ''Pinus dabeshanensis'') as vulnerable and var. ''mastersiana'' as endangered. ''Pinus armandii'' has also been reported in the past from Hainan off the south coast of China, and two islands off southern Japan, but these pines differ in a number of features and are now treated as distinct species, Hainan white pine ''Pinus fenzeliana'' and Yakushima white pine ''Pinus amamiana'' respectively. 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 armandii」の詳細全文を読む スポンサード リンク
