Fagus japonica, known as the Japanese beech, Japanese blue beech or in Japanese as inubuna ("dog buna") or kurobuna ("black buna"), is a deciduous tree of the beech family Fagaceae.
Description
It reaches 25 metres in height.[2] The growth habit is often multi-trunked.[3] Bark is smooth and grey. The simple leaves are arranged alternately along the branch. They are slightly pubescent and slightly glaucous beneath, with 10–14 pairs of lateral nerves. Fruiting peduncles are 3–4 cm long and glabrous.[4]
Taxonomy
Fagus is subdivided into two subgenera: Engleriana, which are low-branching with yellowish bark, and Fagus, which is high-branching with light-grey bark. Another species of beech is found in Japan, Fagus crenata, which is in subgenus Fagus while F. japonica is in the subgenus Engleriana.[5][6][7]
Distribution and habitat
It is endemic to Japan, where it is one of the main tree species in natural deciduous forests particularly on the Pacific side of the country.[3]
