Elodea is a genus of eight species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog’s-bit family (Hydrocharitaceae), Elodea is native to the Americas[1] and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water.[2] An older name for this genus is Anacharis, which serves as a common name in North America.[3]
The introduction of some species of Elodea into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem and it is now considered a noxious weed in these areas.
