The report of Taraxacum platypecidum for a number of additional provinces and for Korea and Japan (FRPS 80(2): 43 1999; Higher Pl. China 11: 778. 2005) is probably incorrect. However, although not yet seen by the authors among the specimens studied, the species should be looked for in the mountainous provinces adjacent to Hebei and Shanxi.
