Salvinia minima is a species of aquatic, floating fern that grows on the surface of still waterways. [1] It is usually referred to as common salvinia or water spangles . Salvinia minima is native to South America, Mesoamerica, and the West Indies and was introduced to the United States in the 1920s–1930s. [ 2 ]
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.

S. minima and S. natans have four free standing hairs connected at a single base. The Giant Salvinia , as well as S. auriculata, and other closely related species, display the most complex hairs: four hairs grow on a shared shaft; they are connected at their tips. These structures resemble microscopic eggbeaters and are therefore referred to as ...
Cyrtobagous salviniae is a species of weevil known as the salvinia weevil. It is used as an agent of biological pest control against the noxious aquatic plant giant salvinia (Salvinia molesta). The adult weevil is about 2 millimeters long. It is brown in color during its first few days of adult life and soon turns shiny black.
Salvinia molesta, commonly known as giant salvinia, or as kariba weed after it infested a large portion of Lake Kariba between Zimbabwe and Zambia, is an aquatic fern, native to south-eastern Brazil. [1] It is a free-floating plant that does not attach to the soil, but instead remains buoyant on the surface of a body of water.
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 ...
Salvinia stem-borer moths lay their eggs on water plants like Azolla caroliniana (water velvet), Pistia stratiotes (water lettuce), and Salvinia rotundifolia (water fern). [4] Larval feeding on host plants causes plant death, which makes S. multiplicalis a good candidate for biological control of weedy water plants like Salvinia molesta , an ...
