摘要：
Pulsatilla saxatilis (Ranunculaceae), a new species from Fengcheng in Liaoning province, north-east China, is described and illustrated. Gross-morphologically this species is closely similar to P. chinensis in having 3-foliolate leaves, solitary, erect flowers, and persistent, prolonged styles in fruiting period, but differs by having light blue, whitish-blue or white (vs. violet) sepals and persistent styles 2-2.5 cm (vs. 3.5-6.5 cm) long. Pollen morphology also lends strong support for the description of the new species, with P. saxatilis having pantoporate pollen grains while its putative closest ally, P. chinensis, having tricolpate ones.
