    Alt Name
    Round-leaved Ranunculus
    Description

    The white flowers are typical of other Crowfoots. In Ranunculus omiophyllus they measure about 8 to 12 mm, the petals at least twice as long as the sepals. The leaf lobes are narrowed at the base.

    Habitat

    It grows in shallow water or on wet soil. Typical sites include the margins of ponds and ditches, flushes, damp depressions, gateways and tracks in pastures and on heathland, and the sheltered backwaters of rivers. Unlike Ranunculus hederaceus, it is confined to acidic, mesotrophic or oligotrophic soils.

    Life History

    UK Status

    Ranunculus omiophyllus remains frequent in W. Britain and S. Ireland, where there are many more records than there were in the 1962 BSBI Atlas. The decline at the fringes of its range was already discernible in the 1962 Atlas, and is now much more marked.

    VC55 Status

    Scarce in Leicestershire and Rutland where it is almost confined to the Charnwood area. In the 1979 Flora survey of Leicestershire it was found in 8 of the 617 tetrads.
