Saussurea nepalensis is illegitimate because Sprengel cited Centaurea taraxacifolia in synonymy but did not take up the epithet, which was at that time still available in Saussurea. Candolle also should have used the earlier epithet, "taraxacifolia," when he transferred the name to Aplotaxis. When C. B. Clarke validated the nomen nudum S. eriostemon by Wallich, another nomen nudum, S. taraxacifolia, used for a different taxon by Wallich, had already been validated by Candolle, so the earliest epithet "taraxacifolia" was no longer available in Saussurea.
