The rare and endangered Miyabe’s maple, named after the Japanese botanist Kingo Miyabe (1860-1951), is native to Japan. The dark green leaves are palmate, with each “finger tip” rounded, distinguishing it clearly from the native Norway maple (A. platanoides). The seeds, or samaras, are joined as in-line pairs, in contrast to many maple species whose samaras are V- or U-shaped.
Miyabe’s maple was planted in the early 1930s at Mustila on the warm, steep Etelärinne (Southern slope), where it is protected from north winds by pine forest. Cold winters have damaged the trees but they have stubbornly survived, though remaining rather small.
