• The Saussurea nipponica complex was examined with enzyme electrophoresis. Earlier morphological evidence suggested that the complex comprises S. sugimurai and seven subspecies of S. nipponica. Electrophoretic evidence supports the separation of the two species and the subspecies classification of S. nipponica. Nei's genetic distance (D=0.19) between S. sugimurai and S. nipponica exceeds the estimated infraspecific level. Saussurea nipponica is newly defined as a species composed of seven infraspecific taxa which have their own distribution ranges and habitats. They are in a very early stage of differentiation. The extensive morphological diversity in S. nipponica is presumed to be a result of geographical isolation under strong environmental selection.
