''Chamaecyparis obtusa'' (Japanese cypress, hinoki cypress or hinoki; (日本語:檜 or 桧, ''hinoki'')) is a species of cypress native to central Japan. It is a slow-growing tree which grows to 35 m tall with a trunk up to 1 m in diameter. The bark is dark red-brown. The leaves are scale-like, 2-4 mm long, blunt tipped (obtuse), green above, and green below with a white stomatal band at the base of each scale-leaf. The cones are globose, 8-12 mm diameter, with 8-12 scales arranged in opposite pairs. The related ''Chamaecyparis pisifera'' (sawara cypress) can be readily distinguished in its having pointed tips to the leaves and smaller cones.〔〔 == Spreading and uses == The plant is spread in Japan. A similar cypress found on Taiwan is treated by different botanists as either a variety of this species (as ''Chamaecyparis obtusa'' var. ''formosana'') or as a separate species ''Chamaecyparis taiwanensis''; it differs in having smaller cones (6-9 mm diameter) with smaller scales, and leaves with a more acute apex.〔〔 It is grown for its very high quality timber in Japan, where it is used as a material for building palaces, temples, shrines, traditional ''noh'' theatres, baths, table tennis blades and masu. The wood is lemon-scented, light pinkish-brown, with a rich, straight grain, and is highly rot-resistant. For example, Horyuji Temple and Osaka Castle are built from hinoki wood. The hinoki grown in Kiso, used for building Ise Shrine, are called 御神木 ''go-shin-boku'' "divine tree". It is also a popular ornamental tree in parks and gardens, both in Japan and elsewhere in temperate climates, including western Europe and parts of North America. A large number of cultivars have been selected for garden planting, including dwarf forms, forms with yellow leaves, and forms with congested foliage. It is also often grown as bonsai. Hinoki (and sugi) pollen is a major cause of hay fever in Japan. 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「Chamaecyparis obtusa」の詳細全文を読む スポンサード リンク
