Ecology
A rhizomatous perennial herb with submerged but no floating leaves, P. lucens grows in relatively deep, calcareous water in lakes, larger rivers, canals, flooded chalk- and gravel-pits and major fenland drains. It is found in clear, nutrient-poor, unpolluted waters as well as more eutrophic and turbid sites. 0?380 m (Malham Tarn, Mid-W. Yorks.).
Status
Native
Trends
P. lucens remains frequent in some areas of England and Ireland, although there is evidence for decline in Surrey since 1930 and at the northern edge of its English range. It has declined more markedly in E. Scotland, apparently being more susceptible to eutrophication there.
