Taraxacum grypodon was also reported from E Xizang (FRPS 80(2): 42. 1999; Higher Pl. China 11: 777. 2005), but a revision of the material is required.
As there are no ripe achenes in the authentic material of Taraxacum grypodon, their description is compiled on the basis of Anonymous 8486 (PE, no. det. 22956), from Qinghai.
