''Fagus orientalis'', commonly known as the Oriental beech, is a deciduous tree in the beech family Fagaceae. It is native to Eurasia, in Eastern Europe and Western Asia. ==Description== ''Fagus orientalis'' is a large tree, capable of reaching heights of up to tall and trunk diameter, though more typically tall and up to trunk diameter. The leaves are alternate, simple, and entire or with a slightly crenate margin, long and broad, with 7–13 veins on each side of the leaf (6–7 veins in ''F. sylvatica''). The buds are long and slender, long and thick, but thicker, till , where the buds include flower buds. The flowers are small catkins which appear shortly after the leaves in spring. The seeds are small triangular nuts long and wide at the base; there are two nuts in each cupule, maturing in the autumn 5–6 months after pollination. The cupule differs from that of European Beech in having flattened, slightly leaf-like appendages at the base (slender, soft spines in European Beech). 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「Fagus orientalis」の詳細全文を読む スポンサード リンク
