|Best Time to See|
A simple water plant with whorls of narrow leaf-like branches along its length.
It is fairly robust with short ‘leaflets’ as well as long fronds in each whorl.
It can be found at about six sites, scattered across southern England.
Shallow, slowly moving water such as ditches and rivers in chalk or limestone areas.
Classified as Endangered.
Smothering by stronger water plants is probably its main threat, although another is nutrient enrichment of the water from fertilisers.
