Scorzonera transiliensis is closely related to S. iliensis and said to be mainly distinguished by its dark orange florets (Lipschitz, Fl. URSS 29: 84. 1964). It is endemic to the Zailiyskiy and Kungey Alatau (SE Kazakhstan, N Kyrgyzstan) and the Ketmen range of the Tien Shan (SE Kazakhstan) and Tian Shan (NW China). It has been listed for Xinjiang by C. H. An (Fl. Xinjiang. 5: 395. 1999), and the above description is based on that work and the original description. The status of this taxon requires further studies.
