Pulsatilla chinensis var. kissii (Mandl) S. H. Li & Y. H. Huang (Fl. Pl. Herb. Chinae Bor.-Orient. 3: 162. 1975) has been proposed for plants growing on dry slopes in S Liaoning. The basionym Pulsatilla ´ kissii Mandl (Oesterr. Bot. Z. 71: 178. 1922) was originally described as a hybrid between P. chinensis and P. cernua which it seems quite likely to be.

Pulsatilla chinensis is used medicinally.
