Maple - Japanese maple

Japanese: ウリカエデ - うりかえで

A deciduous shrub or small tree of the maple family (APG classification: Sapindaceae). Also known as the Meurinoki. The bark is green like that of the Melon Maple, but the wood and leaves are small. The leaves grow opposite each other, with petioles 1.5-3 cm long and blades 4-8 cm long and 3-6 cm wide, ovate, often shallowly divided into three lobes and with fine sawtooth edges. The winter buds have two pairs of scales. Dioecious. The flowers are small, pale yellow flowers, and about 10 flowers bloom in a raceme in April. They are distributed in temperate to subtropical mountain areas from Fukushima Prefecture west of Honshu, Shikoku, and Kyushu, and are often found on sunny roadsides and secondary forests.
