Hong et al. (Acta Phytotax. Sin. 32: 349–355. 1994) recognized two species of Paeonia in Xinjiang: P. anomala (including in synonymy P. intermedia ) and P. sinjiangensis (including in synonymy P. altaica ). In fact, P. sinjiangensis and P. altaica are both synonyms of P. anomala, whereas P. intermedia is a distinct species.
