Description

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]
