Saussurea lyratifolia was placed in S. subg. Frolovia by C. Shih and S. Y. Jin (FRPS 78(2): 58. 1999). As all other former members of this subgenus are now accommodated in different genera, S. lyratifolia is now placed in S. subg. Saussurea. The typical double pappus and the capitula and synflorescence structure leave no doubt that this species belongs to Saussurea s.s. and not to one of the segregates. It is very similar to S. laneana W. W. Smith from India (Sikkim). Further studies are needed to investigate if this is indeed the same species.
