Abstract
Saussurea pseudogracilis Kitam. Is characterized by its slender leaves, small involucre and small number of involucral bracts compared to Saussurea gracilis Maxim. But some taxonomists insist that it is hard distinguih s. pseudogracilis from S. pseudogracilis. We tried to discern taxonomic identification of S, pseudogracilis by measuting and analyzing 45 qualitative characters on 165 spec-imen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters on 165 spec-imen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters but also by quan-titative characters even on statistical analysis(PCA). Therefore, S. pseudogracilis is not independent taxonomic species and it is proper to consider S. pseudogracilis as synonym of S. gracilis.
