Despite its name, this is not such a common species as some other water-crowfoots.
It has both floating, lobed leaves and submerged finely dissected leaves. It is found in ponds, drains and slow-moving streams.
All names: Ranunculus aquatilis L.; Ranunculus aquatilis sens. str. L.; Ranunculus aquatilis ssp. aquatilis L.; Ranunculus heterophyllus Weber; Ranunculus radians Revel
