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 Batrachium

Herbs perennial or annual , aquatic or semiterrestrial, with stems and leaves often submersed . Leaves alternate, subsessile to long petiolate , leaf blade usually submersed, 2--5 × dissected , ultimate segments filiform or narrowly linear , sometimes floating and then blade 3-lobed, not finely dissected. Inflorescence a solitary, leaf-opposed flower. Flowers bisexual , actinomorphic . Receptacle conical or subulate . Sepals (4 or) 5, caducous . Petals (4 or) 5, usually white, with yellow base , rarely entirely yellow, obovate , base shortly clawed, with a nectary pit above claw , apex rounded . Stamens few or numerous ; anthers latrorse . Carpels numerous; ovule 1 per carpel. Style with adaxial stigmatic surface. Aggregate fruit ovoid or globose ; achenes obovoid , slightly bilaterally compressed , transversely rugose .

About 20 species: S Africa, Asia, SE Australia, Europe, North and South America; eight species (one endemic) in China.

The separation of Batrachium from Ranunculus is not clear-cut and many botanists prefer to include the former genus within the latter. All species are aquatic or grow on wet mud .[2]
