A small, rosette-forming perennial herb of oligotrophic lakes with acidic substrates. It is slow-growing, with little ability to withstand shade or competition and is therefore confined to shallow water less than 2 metres deep. Reproduction and dispersal is by seed, which can remain viable for thirty years. 0–745 m (Llyn Bâch, Caerns.).
