Intermediate Bladderwort

A circumpolar species, usually of alkaline waters: interdunal pools and wet flats, fens, marshes, ponds, rivers, lakes; may grow in water a meter or more deep, but thrives and flowers in shallow water.
The bladders in U. intermedia are as long as 5 mm on some individuals, though usually they are 1–3.5 mm. In shallow water (or very recently exposed wet mud) the green leaves when dense often give a mossy appearance (though actually flat and fan-shaped in outline), while the bladder-bearing branches are buried in the substrate.
