Acer capillipes
''Acer capillipes'' (Kyushu Maple or Red Snakebark Maple; (日本語:ホソエカエデ ''hosoekaede'')), is a maple in the same taxonomic section as other snakebark maples such as ''A. pensylvanicum'', ''A. davidii'' and ''A. rufinerve''. It is native to mountainous regions in Japan, on central and southern Honshū (Fukushima Prefecture southwards), Kyūshū and Shikoku islands, usually growing alongside mountain streams.〔Kanagawa Prefecture trees and shrubs: (''Acer capillipes'' ) (in Japanese; (google translation )).

== Characteristics ==
It is a small deciduous tree growing to 10–15 m (rarely to 20 m) tall with a trunk up to 70 cm diameter, though usually smaller and often with multiple trunks, and a spreading crown of long, slender branches. The bark is smooth, olive-green with regular narrow vertical white stripes and small horizontal brownish lenticels; it retains its pattern to the base even on old trees. The leaves are 10–15 cm long and 6–12 cm broad, with three or five lobes, the basal lobes of five-lobed leaves being small; they have a serrated margin, conspicuous veining, and a reddish 4–8 cm petiole. They are matt to sub-shiny green in summer, turning to bright yellow, orange or red in the autumn. The flowers are small, greenish-yellow, produced on 8–10 cm racemes in late spring, erect at first but becoming pendulous, with male and female flowers on different racemes. The samara nutlets are 5 mm long, with a 2 cm long wing.〔〔〔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.〕
It can be distinguished from the related ''Acer rufinerve'' (Japanese, ウリハダカエデ ''urihadakaede''), with which it sometimes grows, by the reddish petioles, the hairless or only thinly hairy leaves (contrasting with the rufous hairs on the underside of ''A. rufinerve'' leaves), and in flowering later in spring well after the leaves appear.〔
