A small annual or perennial which grows in shallow, still or very slowly flowing water. It is most frequent in ponds, dune-slacks and drainage ditches, but it is also found in larger sites if they are sheltered. It tolerates a range of water chemistry but is most frequent in mesotrophic or eutrophic water. 0-310 m (Alston Moor, Cumberland).
The aquatic Ranunculus species are difficult to identify, and this early-flowering plant is easily overlooked. Under-recording rather than decline may therefore be the reason for the concentration of pre-1970 records in some areas as there is little evidence of decline in neighbouring counties.
Circumpolar Wide-boreal element.
