Stems 5–30 (50) cm tall. Basal leaves develop at the end of flowering, long-petiolate, with lamina more or less rounded, palmately dissected into three sessile share; parts of lamina are twice-thrice dissected into dentate lobes of the second order (in number 18–40) 2–4 mm wide.

Fruitlets pubescent with long pinnate aristae 2.5–3.5 cm long (Figure 1, B).

Relationship. This taxon differs from closely related species Pulsatilla patens s.str. by yellowish, less open flower, tepals broader and abruptly pointed or obtuse; from Pulsatilla uralensis (Zämelis) Tzvelev by narrower segments sessile leaves; from Pulsatilla angustifolia Turcz. by wider and not numerous, sessile leaf lobes, later development of leaves; from all these species by the range (from the Altai in the west to the Transbaikalia in the east and from Tuva in the south to the latitude of NizhnyayaTunguska river in the north) and attraction to steppe habitats.
