Hydrocharitaceae genera

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 and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water. An older name for this genus is Anacharis, which serves as a common name in North America.

Vallisneria (named in honor of Antonio Vallisneri) is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Australia, Europe, and North America.

Najas, the water-nymphs or naiads, is a genus of aquatic plants. It is cosmopolitan in distribution, first described for modern science by Linnaeus in 1753. Until 1997, it was rarely placed in the Hydrocharitaceae, and was often taken as constituting (by itself) the family Najadaceae.

Hydrocharis is a genus of aquatic plants in the family Hydrocharitaceae described as a genus by Carl Linnaeus in 1753. Species range across much of Europe and Asia, northwestern and central Africa, New Guinea, and the Americas from the eastern and central United States to Argentina and Chile. Species are naturalized in parts of California, northeastern North America, southern tropical Africa, and Australia.

Hydrilla (waterthyme) is a genus of aquatic plants, usually treated as containing just one species — Hydrilla verticillata, but some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa, and Australia, with a sparse, scattered distribution; in Australia it occurs from the Northern Territory to Queensland and New South Wales.

Stratiotes is a genus of submerged aquatic plant commonly known as water soldiers, described as a genus by Linnaeus in 1753. Several specific names have been coined within the genus, but at present only one is recognized: Stratiotes aloides. native to Europe and NW Asia.

Blyxa is a genus of an aquatic plant of the family Hydrocharitaceae described as a genus in 1806.

genus of plants in the family Hydrocharitaceae

Enhalus is a monotypic genus of marine flowering plants. The sole species is Enhalus acoroides. Enhalus is a large seagrass native to coastal waters of the tropical Indian and Western Pacific Oceans. It is the only species of seagrass that does aerial surface pollination in which the pollen and the styles remain dry. Enhalus is surface pollinated with male flowers that detach from the plant to float on the surface until they reach a female flower where pollination can occur. Enhalus acoroides is considered a slow-growing, "climax" species.

Halophila is a genus of seagrasses in the family Hydrocharitaceae, the tape-grasses. It was described as a genus in 1806. The number of its contained species, and its own placement in the order Alismatales, has evolved.

Lagarosiphon is a genus of aquatic plants described as a genus in 1841. It is native to Africa and Madagascar. It is dioecious, with male and female flowers produced on separate plants.

Ottelia is a genus of an aquatic plant family Hydrocharitaceae described as a genus in 1805. The genus is native to tropical and subtropical regions of Africa, Asia, South America, and Australia.

Nechamandra is a monotypic genus of an aquatic plant family Hydrocharitaceae. The sole species is Nechamandra alternifolia. It is found in slow moving fresh water.
