Acer palmatum
Siebold's Maple is not as rare in cultivation as it seems. Specimens are often mistaken for and mislabeled as similar species in the series "Palmata", such as "Acer japonicum", "Acer shirasawanum" and "Acer palmatum"; it is also sometimes confused with "Acer pseudosieboldianum" (Korean Maple or Keijo Maple), a closely related species from the adjacent mainland of northeastern Asia.
