Note	Many non-Japanese authors describe that Sanguisorba hakusanensis Makino is a synonym of Sanguisorba obtusa Maximovicz (syn. Poterium obtusum (Maximovicz) Franchet & Savatier). In fact there is no obvious deference between Sanguisorba hakusanensis Makino and Sanguisorba obtusa Maximovicz except plant size (Sanguisorba obtusa Maximovicz is 30-50cm tall) and their distribution areas. However many Japanese authors may believe that Sanguisorba hakusanensis Makino is different species from Sanguisorba obtusa Maximovicz, and argue that Sanguisorba hakusanensis Makino occurs in limitted high mountains in Central region and Sanguisorba obtusa Maximovicz occurs only in some limitted high mountains in Tohoku region of Honshu. Possibly Sanguisorba hakusanensis Makino will be identified as a synonym of Sanguisorba obtusa Maximovicz Reexamination should be done. Also there is a similar species in Korea - Sanguisorba hakusanensis Makino var. coreana Nakai. However possibly Sanguisorba hakusanensis Makino var. coreana Nakai will be identified as a synonym of Sanguisorba obtusa Maximovicz too.
