''Abies firma'', the momi fir, is a species of fir native to central and southern Japan, growing at low to moderate altitudes of 50-1600 m. ''Abies firma'' is a medium-sized to large evergreen coniferous tree growing to tall and in trunk diameter, with a broad conical crown of straight branches rising at an angle of about 20° above horizontal. The bark is scaly grey-brown, with resin blisters on young trees. The shoots are grooved, buff to grey-brown, glabrous or finely pubescent. The leaves ("needles") are flattened, long and broad, spread at nearly right angles from the shoot; the apex is sharp, bifid (double-pointed) on the leaves of young trees, single-pointed on mature trees. They are bright green above, and greyish-green below with two broad stomatal bands. The cones are long by wide, green maturing yellow-brown, tapering to a broad bluntly rounded apex. The scale bracts are exserted , triangular. The seeds are long with a wedge-shaped wing long, are released after the cones disintegrate at maturity in October. Momi fir is sometimes, but not commonly, used as an ornamental tree, particularly in warm temperate regions with hot, humid summers such as the southeastern United States. ==References== * *(Gymnosperm Database ) 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「Abies firma」の詳細全文を読む スポンサード リンク
