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.

This species is classed as NEAR THREATENED in the Red Data List of Vascular Plants 2016.

These photographs were all taken using a long zoom lens, it was a windy day and I didn’t have a tripod with me. To get any closer to the flowers would have meant climbing over a barbed-wire fence, crossing about 6 ft of really dense brambles and several other impossible feats of endurance!  All in all, they’re not too bad. Next time I find these plants, I hope they’ll be closer.
