Salvinia or watermosses [1] is a genus of free-floating aquatic ferns in the family Salviniaceae.The genus is named in honor of 17th-century Italian naturalist Anton Maria Salvini, and the generic name was first published in 1754 by French botanist Jean-François Séguier in Plantae Veronenses, a description of the plants found around Verona.

A third species, the grasshopper Paulinia acuminata, was considered, but not released in Australia. However, this grasshopper has been deliberately released for control of Salvinia molesta in parts of Africa, Sri Lanka and India, and accidentally in Puerto Rico. [13] The giant gourami has long been known to prefer S. molesta and feed on it ...
Salviniales are all aquatic and differ from all other ferns in being heterosporous, meaning that they produce two different types of spore (megaspores and microspores) that develop into two different types of gametophyte (female and male gametophytes, respectively), and in that their gametophytes are endosporic, meaning that they never grow outside the spore wall and cannot become larger than ...

The flood plain in general and associated villus in particular have a high diversity of both smaller and larger plant species. There are 231 plant species that have recorded from Handapan and Bendiya villus and marsh forests, which is the largest villu of 796 hectares (3.07 sq mi) within the Mahaweli River floodplain. Saturated soil and ...
The Salviniaceae contain the two genera Azolla and Salvinia, [4] with about 20 known species in total. [5] The oldest records of the family date to the Late Cretaceous. [ 6 ] Azolla was previously placed in its own family, Azollaceae , but research has shown Azolla and Salvinia to be sister genera with the likely phylogenic relationship shown ...
