Family: Hydrocharitaceae.

Native of North America.

Occurrence: A widespread weed of still and flowing water, growing in water to a depth of up to 3 metres or more.

Identification:

Although an introduced plant, it is usually beneficial. The coating of bacteria, algae etc help remove toxins and impurities from the water. In cold climates it is usually not a problem plant. In New South Wales it may clog water channels. It spreads from fragments of the plant. The small flowers are on long slender stalk.
