Note	Some Japanese authors strongly believe that Lysionotus apicidens (Hance) Yamazaki is not a synonym of Lysionotus pauciflorus Maximowicz and that Lysionotus pauciflorus Maximowicz (var. pauciflorus) is endemic to Japan. Also some Japanese authors believe that Lysionotus warleyensis Willmott is not a synonym of Lysionotus pauciflorus Maximowicz. However non-Japanese authors may not agree such an opinion. This argument should be settled only based on scientific DNA analysis but not on outlook of the plant.
