Family Ranunculaceae

Herbs perennial or annual , sometimes subshrubs or herbaceous or woody vines . Leaves basal and cauline, alternate, rarely opposite or whorled , simple or variously compound , palmately nerved, rarely penninerved , with or without stipules. Inflorescence a simple or compound monochasium, dichasium, simple or compound raceme, or flowers solitary. Flowers bisexual , sometimes unisexual , actinomorphic , rarely zygomorphic, hypogynous. Sepals 3--6 or more, free , petaloid or sepaloid , imbricate or sometimes valvate in bud. Petals present or absent, 2--8 or more, free, usually with nectaries. Stamens numerous , rarely few, free; filaments linear or filiform ; anthers latrorse , introrse , or extrorse ; sometimes some sterile stamens becoming staminodes. Carpels numerous or few, rarely 1, free, rarely connate to various degrees ; ovary with 1 to many ovules. Fruit follicles or achenes, rarely capsules or berries . Seeds small, with abundant endosperm and minute embryo.

About 60 genera and 2500 species: worldwide, but richly represented in N temperate regions , particularly in E Asia; 38 genera (four endemic) and 921 species (604 endemic) in China.[1]

Genus Pulsatilla

Herbs perennial , often covered with long soft hairs . Rhizome erect . Leaves basal, rosulate; petiole long; leaf blade palmately or odd pinnately divided ; veins palmate. Scape with 3 bracts forming a bell-shaped involucre; involucral bracts basally connate and apically ± deeply divided into numerous lobes . Flower solitary, bisexual . Sepals 5 or 6. Petals absent. Stamens numerous, outermost whorl staminodial except in Pulsatilla kostyczewii; anthers yellow or purple, oblong , narrowly ellipsoid , filiform , or linear , with one longitudinal vein . Pistils numerous; ovule 1 per ovary. Styles long linear, pilose , strongly elongated and plumose when mature . Infructescence globose . Achenes small, spindle-shaped , pilose, with a long plumose beak formed by persistent style.

About 33 species: Asia, Europe, North America; 11 species (one endemic) in China.

Although Pulsatilla can easily be distinguished from Anemone by the former having a long, plumose beak on the achenes formed by the persistent style, phylogenetic studies have shown that they are probably congeneric .[2]

Habitat

Biome: Terrestrial [3].

Ecology: The species occurs on dry, grassy sites on limestone and dolomite substrate from the hilly areas to the submontane vegetation belt (Mere?a and Hodálová 2011). This plant grows in the following Habitats Directive listed habitats (Commission of the European Communities 2009):

Notes

A tentatively accepted name in the RHS Horticultural Database.

Where Pulsatilla subslavica occurs with other related species, hybridization takes place: in the southern part of the range with P. grandis, in the northern part with P. slavica. This backcrossing results in transient individuals, even whole populations, which are difficult to identify (Mere?a and Hodálová 2011).[3].
