This variety was accepted in FRPS (p. 418), with the place of publication cited as “Bull. Bot. Res.[, Harbin] 1(4): 1981,” i.e., without a page number. The name was published nowhere in that journal, and no validating description, diagnosis, nor indication of type was included in FRPS. It is therefore validated here. One of us (Robertson) has seen no specimens of this variety.

Rocky slopes; ca. 1700 m. SC Shaanxi (Zhongnan Shan).
