This plant can be found in soggy areas of "dry" land as well as floating on the water. This one was floating on the water some distance away from the bank so this is an image using the hand held zoom lens at maximum (x10). The water plant submerged near the surface is Ceratophyllum demersum (Rigid Hornwort).

Apart from some high mountain regions in Wales and the north of Scotland this plant can be found all over the British Isles and Ireland.
