Acer micranthum, the small-leaved maple, is a species of flowering plant in the family Sapindaceae in the snakebark maple group, native to Japan, on Honshū, Kyūshū and Shikoku. Its Japanese name is the Komine maple (Japanese: コミネカエデ, Hepburn: Kominekaede). It is most closely related to Acer tschonoskii, which replaces it further north and at higher altitudes in Japan; they have very similar leaf form. * Tree in cultivation, Denmark * Leaves, Rogów Arboretum, Poland * Illustration by Siebold & Zuccarini
