Egeria is a genus of two species of aquatic plants in the family Hydrocharitaceae described as a genus in 1849.[3][2] native to warm-temperate South America.[4]
The genus was formerly included in the related genus Elodea, from which it differs in having the leaves in whorls of four or more, not three, and in having more conspicuous flowers with larger (particularly broader) petals.[5][6]
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.[7]
