No specimens of this species from China have been seen by the authors. It is likely that all the specimens, including the lectotype of Hedysarum falconeri (Falconer 441), that were cited as being from "West Tibet" by Baker (Fl. Brit. India 2: 146. 1846) and by H. Ohashi and Tateishi (Fl. E. Himalaya, 3rd. Rep. 377. 1975) are actually from the Karakoram mountains in NW Pakistan.
