Tzvelev (Fl. URSS 26: 412. 1961) suggested that this species would have to be removed from Hippolytia. Bremer and Humphries (Bull. Nat. Hist. Mus. London, Bot. 23: 106. 1993) also regarded this species as anomalous, and it was subsequently transferred by Grubov and Filatova to the new genus Poljakovia (Novosti Sist. Vyssh. Rast. 33: 227. 2001).

Filatova (Rast. Tsentral. Azii 14a: 30-31. 2007) treated Hippolytia alashanensis and H. kaschgarica as distinct species in Poljakovia: P. alashanensis with lower cauline leaves and leaves of sterile shoots pinnatisect, lateral segments linear, apex shortly cuspidate; and P. kaschgarica with lower cauline leaves and leaves of sterile shoots pinnatifid, lateral segments oblong-lanceolate, entire, apex subobtuse.
