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.
