Ynghylch

Lesser spearwort is a common, hairless perennial of fresh water, such as the edges of ponds, lakes and streams, and in marshes, water meadows and bogs. A member of the buttercup family, it displays the familiar sunshine-yellow flowers that define this group. However, its leaves are undivided and spear-like, hence its name, 'Spearwort'. It has distinctive, scrambling red-tinged stems that can root at leaf junctions.
