Acer griseum (Paperbark Maple; Template:Zh) is a species of maple native to central China, in the provinces of Gansu, Henan, Hubei, Hunan, Shaanxi, Shanxi, and Sichuan, at altitudes of 1,500–2,000 m.[1]
It is a small to medium-sized deciduous tree, reaching 6-9 m (20-30 ft) tall, 5-6 m (15-25 ft) wide, with a trunk up to 70 cm (2 ft) diameter.[2] The bark is smooth, shiny orange-red, peeling in thin, papery layers; it may become fissured in old trees. The shoots are densely downy at first, this wearing off by the second or third year and the bark exfoliating by the third or fourth year. The leaves are compound, with a 2–4 cm petiole with three leaflets, each 3-10 cm long and 2-6 cm broad, dark green above, bright glaucous blue-green beneath, with several blunt teeth on the margins. The flowers are androdioecious, produced in small corymbs in spring, the fruit being a paired samara with two winged seeds about 1 cm long with a 3 cm wing.[1][3]
Paperbark Maple is widely grown as an ornamental plant in temperate regions. It is admired for its decorative exfoliating bark, translucent pieces of which often stay attached to the branches until worn away. It also has spectacular autumn foliage which can include red, orange and pink tones.
Recent attempts have been made to acquire new seed stock from wild populations in China because it is believed that the current gene pool of cultivated specimens is very small. Propagation of Acer griseum is somewhat difficult as seeds have the same parthenocarpic tendencies as those of Acer maximowiczianum.[4]
