Alismataceae genera

Alisma is a genus of flowering plants in the family Alismataceae, members of which are commonly known as water-plantains. The genus consists of aquatic plants with leaves either floating or submerged, found in a variety of still water habitats around the world (nearly worldwide). The flowers are hermaphrodite, and are arranged in panicles, racemes, or umbels. Alisma flowers have six stamens, numerous free carpels in a single whorl, each with 1 ovule, and subventral styles. The fruit is an achene with a short beak.

Sagittaria is a genus of about 30 species of aquatic plants whose members are referred to by the Native American word wapato () and a variety of other common names, including arrowhead, duck potato, swamp potato, tule potato, and katniss. Most are native to South, Central, and North America, but there are also some from Europe, Africa, and Asia.

Echinodorus, commonly known as burhead, is a genus of plant in the family Alismataceae. It contains a single species, Echinodorus berteroi, which is native to the Americas. The name is derived from Ancient Greek '''' 'rough husk', and '''' 'leathern bottle', alluding to ovaries, which in some species are armed with persistent styles, forming prickly head of fruit.

Luronium natans is a species of aquatic plant commonly known as the floating water-plantain. It is the only recognized species in the genus Luronium, native to western and central Europe, from Spain to Britain to Norway east to Ukraine.

Damasonium is a genus of six species of flowering plants in the family Alismataceae, commonly known as starfruit and by the older name thrumwort. The genus has a subcosmopolitan but very patchy distribution.

Hydrocleys is a genus of aquatic plants in the Alismataceae, native to the Western Hemisphere, though one is naturalized elsewhere and sold as an ornamental for decorative ponds and artificial aquatic habitats. At present (May 2014), five species are recognized: {| class="wikitable" |- ! Image !! Scientific name !!

Caldesia is a genus of aquatic plants. It includes three living species widespread across Europe, Asia, Africa and Australia. The genus "has an extensive Oligocene through Pleistocene fossil record in Eurasia," and has been found in fossil strata of the United States (Idaho and Vermont) as well. Ten fossil species have been described for the genus.

Baldellia is a genus of aquatic plants commonly known as lesser water-plantains. It includes three species found across much of Europe and the Mediterranean from Ireland and the Canary Islands to Turkey and Estonia. The genus is named in honor of the Italian nobleman Bartolommeo Bartolini-Baldelli. Baldellia is very closely related to Echinodorus.

Helanthium is a genus of plants in the Alismataceae, native to the Western Hemisphere. At present (May 2014), three species are recognized:

Limnocharis is a genus of plants in the family Alismataceae, native to Mexico, Central America, the West Indies and South America, but naturalized in China, India, and Southeast Asia as well. Two species are recognized as of May 2014:

Ranalisma is a genus in the family Alismataceae. It includes two species; one from tropical Africa (R. humile) and the other (R. rostrata) from southeast Asia.

Wiesneria is a genus in the family Alismataceae. The plant usually lives in natural temporary water pools on lateritic plateaus. Wiesneria triandra was first described in the south of the Indian state of Maharashtra. They are well spread out over the regions they occupy and have no common uses, making them of least concern.

Limnophyton is a genus in the family Alismataceae. It includes five species from the Old World tropics. Three species are recognized as of May 2014:

Albidella is a genus of flowering plants in the family Alismataceae. It includes four species native to the tropics.

Butomopsis is a genus of plants in the family Alismataceae. It contains only one species, Butomopsis latifolia. native to tropical Africa (from Senegal to Sudan to Mozambique), South Asia (India, Nepal, Bhutan, Bangladesh), Southeast Asia (Java, Burma, Laos, Thailand, Vietnam, Yunnan) and northern Australia (Queensland and Northern Territory).

Burnatia is a genus in the family Alismataceae. It includes only one currently recognized species, Burnatia enneandra. It is native to tropical and southern Africa from Senegal to Tanzania to South Africa. Among genera of the Alismataceae, it can be distinguished by not having a differentiated perianth (in Burnatia the petals are reduced), and being dioecious, with male and female flowers on separate individuals. Male flowers have 6 to 9 stamens and female flowers have many carpels and up to 2 staminodia.

Astonia is a monotypic genus in the Alismataceae family, containing the sole species Astonia australiensis found in Queensland, Australia. It is sometimes included in the genus Limnophyton and was named in honour of Australian botanist Helen Aston.
