(Fagus crenata)
Fagus crenata, known as the Japanese beech, Siebold's beech, or buna, is a deciduous tree of the beech genus, Fagus, of the family Fagaceae. It is native to Japan, where it is widespread and often one of the dominant trees of Japan's deciduous forests. It is found from the Oshima Peninsula in Hokkaid? south to the ?sumi Peninsula in Ky?sh?. In north-east Honsh? it grows in large stands from sea level up to 1,400 metres (4,600 ft) but in the south-west of its range it is restricted to mountainous areas and occurs in small, isolated populations. It grows in well-drained, loamy or sandy soils. It reaches 35 metres (115 ft) in height. The crown is rounded and the bark is smooth and grey. The simple leaves are arranged alternately along the branch. They are broadest towards the base and have 7 to 11 pairs of veins. The nut has a short thick stalk, 15 millimetres (0.6 in) long. There are flattened green whiskers at the base of the husk of the nut. The flowers are wind-pollinated. The young leaves and seeds are edible.
