a species of trees of the genus Maple (Acer) of the family Sapindaceae. Naturally grows in China (Anhui, Hubei, Hunan, Jiangxi, Sichuan, Zhejiang) and Japan (Honshu, Kyushu, Shikoku)
The species is named after Karl Ivanovich Maksimovich (1827-1891), a Russian botanist, academician of the Imperial St. Petersburg Academy of Sciences, a researcher of the flora of the Far East and Japan. Slender deciduous tree, reaching 15-20 m in height, usually shorter.
The bark is dark gray with a black tint.
The leaves have petioles 3-5 cm long and three leaflets; leaflets with smooth edges, oblong, 5-15 cm long and 3-6 cm wide, densely covered with soft down. Fruits are hard, horizontally outstretched double lionfish, 3.5-6 cm long and 1.2 cm wide, and are often barren, like the Gray Maple
This three-leafed maple is related to such species as the Three-flowered Maple and the Gray Maple and belongs to the Trifoliata section, but differs from them in that its bark does not flake off.
Many old texts describe this species under the synonymous name A. nikoense Maxim., But since Maksimovich also used the name Negundo nikoense Miq. in synonyms, the modern name is recognized as the one that this species calls the MCBN. Mikel pointed out that his Negundo nikoense is not the same plant that Maksimovich called by this name and therefore gave A. nikoense Maxim. new name in honor of Maksimovich The Maksimovich maple was first introduced into cultivation in 1881 when its seeds were brought to the Veitch nursery in England after the maple trees were discovered in the forests of Hokkaido by Charles Maryse. These maples are rarely seen in culture outside of arboretums. The largest specimen in England has a height of up to 17 m and a trunk of 70 cm in diameter
