"Jurinea suidunensis" belongs here, but, to our knowledge, has never been validated by a description or diagnosis. When regarded as conspecific with J. dshungarica (e.g., by Tscherneva, Bot. Zhurn. 86 (12): 88-89. 2001), a concept which is followed here, the latter name has to be adopted as the correct one for this taxon.
