One of a number of species which are difficult to tell apart, this is a plant which is found in brackish, coastal pools. It bears 5-petalled, white, 12-18mm flowers which have deep yellow centres. The 5 sepals are usually blue-tipped. The flowers bloom from April to August. There are two types of leaves – deeply-lobed, floating leaves and thread-like submerged leaves which do not tend to collapse out of water. The nectaries are crescent-shaped. This is a scarce, native annual or perennial and it belongs to the Ranunculaceae or Buttercup family.
I first saw this species near Slade in Co Wexford in 2011 while on a BSBI Field Trip with the Vice-county Recorder for Waterford and Wexford, Paul Green. The photographs were taken in 2012.
