Appearance
The plant has a stem reaching up to 80 centimetres in height. Its basal roots are buried in the underlying mud, while other silvery, shiny roots dangle freely in the water. The leaves are deeply divided as far as the central vein, like the teeth of a double comb, and are completely submerged, but can surface after a drastic fall in water level. The leaves are alternate or connected to the stem in more or less regular whorls. The flowers are hermaphrodite and pollinated by insects and cleistogamy; they appear from May to June. The plant is self-fertile.Distribution
Featherfoil is found in Europe and northern Asia. The species epithet "palustris" is Latin for "of the marsh" and indicates its common habitat.References:
