Snakebark maples are maples belong to the taxonomic section ''Acer'' sect. ''Macrantha''. The section includes 18–21 species, and is restricted to eastern Asia (the eastern Himalaya east to Japan) with the exception of one species in eastern North America.〔Flora of China (draft): (Aceraceae )〕〔Maple World: (Classification of maples )〕〔van Gelderen, C. J. & van Gelderen, D. M. (1999). ''Maples for Gardens: A Color Encyclopedia''.〕〔Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins ISBN 0-00-220013-9.〕 The various species of snakebark maples are most easily distinguished from other maples by their distinctive bark, smooth (at least on young trees), and usually patterned with vertical dark green to greenish-brown stripes alternating with stripes of light green, pinkish or white, sometimes with a bluish tone. Other characters include stalked buds with just one pair of scales, and flowers on arching to pendulous racemes. The samaras are small, and often numerous. They are small deciduous trees, typically 5–15 m tall, rarely to 20 m tall, fast-growing when young but soon slowing down with age, and often short-lived; they typically occur as understorey trees in mountain forests, often along streamsides.〔〔〔 ;Species: * ''Acer capillipes'' - Kyushu Maple, Red Snakebark Maple * ''Acer caudatifolium'' * ''Acer crataegifolium'' - Hawthorn-leaf Maple * ''Acer davidii'' (syn.

All are relatively hardy compared to many other species of maples, and many are widely cultivated as ornamental trees for their bark. Several cultivars and hybrids have been developed in cultivation. == See also == *List of Acer species 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「snakebark maple」の詳細全文を読む スポンサード リンク
