Based on the few differences in ITS sequences and outer morphological traits between Papaver miyabeanum of the Kuril Islands and P. fauriei (Papaveraceae) of Rishiri Island, Hokkaido, the two species are treated as conspecific. However, because of the stable differences in ITS sequences, a tendency toward smaller dimensions in all morphological features, and the somewhat isolated geographical distribution of P. fauriei, we regard the differences to be recognizable at the subspecific level. We therefore propose the name Papaver fauriei (Fedde) Fedde ex Miyabe et Tatew. subsp. shimshirense (Miyabe et Tatew.) Hideki Takah., comb. & stat. nov. for P. miyabeanum of the Kuril Islands.
