"Egeria" is a genus of two species of aquatic plants in the family Hydrocharitaceae, native to warm-temperate South America.

The genus was formerly included in the related genus "Elodea", from which it differs in having the leaves in whorls of four to five or more, not three, and in having more conspicuous flowers with larger (particularly broader) petals.Flora of North America: [http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=111329 "Egeria"] ] Huxley, A., ed. (1992). "New RHS Dictionary of Gardening". Macmillan ISBN 0-333-47494-5.]

"Egeria" is found in many temperate and subtropical regions throughout the world as an introduced, or "alien," species, meaning a species that does not originate from the area in which it is found. In many places, particularly in Europe, fast-growing, adaptable plants such as "Egeria" can spread quickly and cause major damage to native plants and wildlife. [Hisock, Peter. (2005). "Aquarium Plants (Mini Enyclopedia)," p. 146. NY: Barrons. ISBN 0764129899.]
