The Chinese record of Lotus frondosus (Freyn) Kuprianova from Xinjiang (FRPS 42(2): 224, 226. 1998) is based on a misidentification of L. krylovii, as were the records from the former Soviet Union by Kuprianova (Fl. URSS 11: 295. 1945). Lotus corniculatus var. fron­dosus Freyn was described from Turkmenistan and is distributed also in Afghanistan, Pakistan, Uzbekistan, and SW Asia (Iran and Iraq).
