Abstract
Summary: Until recently names accepted by Rehder and Wilson (1913) for Magnolia species in Japan have commonly been followed. Magnolia obovata Thunb., which has been applied to the Japanese Umbrella Tree, is rejected as a superfluous, illegitimate name for M. denudata Desr. (=M. heptapeta) and M. liliiflora Desr. (=M. quinquepeta), and Magnolia hypoleuca Sieb. et Zucc. is accepted as the correct name.
