Taxonomic note : According to the Flora of China, some individuals of Japan with the deeoly divided leaves are recognized as var. platanifolium in Japan, while some of Korea with relatively thinly divided are treated as var. trilobum (Miq.) Ohwi. The latter taxon has already been synomized by Bloembergen (1939).
