The specific epithet was spelled both "qinghaiensis" and "qing­nanensis" in the protologue (heading and figure caption on p. 36, Feb 1997). Later, in the same volume, this was corrected to Oxytropis qing­nanensis (p. 223, Jun 1997). The name O. nangqianensis X. Y. Zhu (Cathaya 11-12: 154. 2000) was published as a nomen novum in the mistaken belief that its replaced synonym was an illegitimate later homonym of O. qinghaiensis Y. H. Wu (1996); see the comments under that species (p. 475). In fact, the name O. nangqianensis was nomen­claturally superfluous when published and is therefore illegitimate.
