● Alpine meadows, montane grasslands; 3000-4600 m. Qinghai, W Sichuan, NW Yunnan.

In Qinghai, several specimens have been found that are morphologically intermediate between Saussurea nigrescens and S. tatsienensis. Both species are very common in the high montane grasslands in the NE part of the Qinghai-Xizang Plateau and probably hybridize where they occur together.
