Ecology
This is our most widespread and frequent floating aquatic plant, often abundant on a wide variety of still or slowly flowing, mesotrophic or eutrophic waters. It also occurs terrestrially on exposed mud, or damp stonework and rocks. Plants rarely flower and reproduction is by vegetative budding. 0-500 m (Brown Clee Hill, Salop).
Status
Native
Trends
There is no evidence that the distribution of this species has changed since the 1962 Atlas, as the overall range is similar and the extra squares in which the species is known have almost certainly resulted from more detailed recording.
World Distribution
Circumpolar Southern-temperate element; widely naturalised outside its native range.
