Ruppia
''Ruppia'', also known as the widgeonweeds, ditch grasses or widgeon grass, is the only extant genus in the family Ruppiaceae, with eight known species. These are aquatic plants widespread over much of the world. The genus name honours Heinrich Bernhard Rupp, a German botanist (1688-1719). They are widespread outside of frigid zones and the tropics. Description The leaf is simple and not rhizomatous. They can be annual (commonly) or perennial (rarely); stem growth is conspicuously sympodial, but sometimes is not. These species are adapted to be in brackish water (and salt marshes). The leaves are small or medium-sized. Their disposition can be alternate, opposite, or whorled (usually alternate except when subtending an inflorescence). Even, lamina keep entire and are setaceous or linear. The leaf just shows one vein without cross-venules. Stomata are not present. The mesophyll leaks calcium oxalate crystals. The minor leaf veins do not present phloem transfer cells and leaks ves ...

Ruppia Maritima
''Ruppia maritima'' is an aquatic plant species commonly known as beaked tasselweed, ditch grass, tassel pondweed and widgeon grass. Despite its scientific name, it is not a marine plant; is perhaps best described as a salt-tolerant freshwater species.Kantrud, H. A. (1991)Classification and Distribution - Wigeongrass (''Ruppia maritima'' L.): A literature review. U.S. Fish and Wildlife Service. The generic name ''Ruppia'' was dedicated by Linnaeus to the German botanist Heinrich Bernhard Ruppius (1689-1719) and the specific name (maritima) translates to "of the sea". Distribution It can be found throughout the world, most often in coastal areas, where it grows in brackish water bodies, such as marshes. It is a dominant plant in a great many shoreline regions. It does not grow well in turbid water or low-oxygen substrates.Kantrud, H. A. (1991)Habitat - Wigeongrass (''Ruppia maritima'' L.): A literature review. U.S. Fish and Wildlife Service.

Ruppia Polycarpa (7597050858)
''Ruppia polycarpa'' is a submerged aquatic herb species in the genus ''Ruppia'' found in shallow brackish waters. It is a common submerged herb on Australasian coasts, including Australia (NSW; SA; Vic; WA) and New Zealand (type locality). It was first described in 1967 by Ruth Mason from a specimenCHR 150837B found near the mouth of the Selwyn River, New Zealand, on the riverbed, on 27 February 1966 by J. Clarke. It grows in "fresh to hypersaline coastal lakes, lagoons and estuaries".

Cymodoceaceae
Cymodoceaceae is a family of flowering plants, sometimes known as the "manatee-grass family", which includes only marine species. The 2016 APG IV does recognize Cymodoceaceae and places it in the order Alismatales, in the clade monocots. The family includes five genera, totaling 17 species occurring in tropical seas and oceans (so-called seagrasses). According to thAP-Websiteit is doubtful if the family Ruppiaceae is distinct enough to be kept apart. The inclusion of the sole genus ''Ruppia'' in Ruppiaceae in Cymodoceaceae is being considered. The plants in the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae form a monophyletic group. Its fossil record shows that Cymodoceaceae was established in its current Indo-West Pacific distribution by the early Eocene and perhaps even during the late Paleocene. Fossils of ''Thalassodendron auriculalopris'' den Hartog and ''Cymodocea floridana'' den Hartog (both extant) were also found in west-central Florida and date back to ...

Ruppia Cirrhosa
''Ruppia cirrhosa'' is a species of aquatic plant known by the common names spiral ditchgrass and spiral tasselweed. It is native to the Americas and Europe, where it grows in freshwater bodies, such as lakes. It is a thread-thin, grasslike perennial herb which grows from a rhizome anchored in the wet substrate. It produces a long, narrow inflorescence tipped with two tiny flowers. As the fruit develops the peduncle of the inflorescence curls into a neat spiral. Taxonomy and nomenclature A lectotype for this name is designated and the name is shown to be a homotypic synonym of '' R. maritima''.Ito, Y., T. Ohi-Toma, C. Nepi, A. Santangelo, A. Stinca, N.
