Taxonomy
Acer pictum is taxonomically complex species, showing morphological variation that corresponds to different geographic regions. Treatments of this variation have ranged from recognizing entities at the species level, to uniting them all under an undivided A. pictum. Further taxonomic study of this group is needed. Five subspecies are provisionally recognized in the Flora of China. These are:
 * Acer pictum subsp. macropterum - China
 * Acer pictum subsp. mono - China, Japan, Korea, Mongolia, and east Russia
 * Acer pictum subsp. pictum - Japan and Korea
 * Acer pictum subsp. pubigerum - China
 * Acer pictum subsp. tricuspis - China
