This is a perennial with a thin – sometimes non-developing – rootstalk. The straight, round and branchy stem is light in color. All of the submerged thin linear dark green leaves are obtuse with pointy tips. The inflorescence is patchy, composed of several closely-seated few-flowered whorls on a thin peduncle, which rises above the water when flowering.
It occurs at smaller depths, and mainly at the littoral oozy bed deposits in smaller lakes, bays of big lakes, quiet rivers and ponds. It often forms big beds along shores.
