Hydromystria
''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.Roberts, M. L., R. L. Stuckey, and R. S. Mitchell. 1981.

Hydrocharis Laevigata
''Hydrocharis laevigata'' is a floating aquatic plant, and is a member of the family Hydrocharitaceae. Common names include West Indian spongeplant, South American spongeplant and Amazon or smooth frogbit. This plant was introduced to North American waterways through use in aquariums and aquascapes. Plant origin and distribution Spongeplant originates from fresh water habitats of tropical and subtropical Mexico Central America, the Caribbean, and South America. It has been introduced to other parts of the world including California, France, Spain, Sweden, Poland, Japan, western and eastern Australia, Zambia, Zimbabwe, and Java. In California it has been introduced as an ornamental pond plant, and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento River delta and the San Joaquin River, and ponds and irrigation canals. It is an invasive species in Chile where it has been found from Elqui River in the north to Carlos Anwandter Natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocharitaceae
Hydrocharitaceae is a flowering plant family which includes 14 accepted genera and a total of ca 135 known species (Christenhusz & Byng 2016). The family holds a number of species of aquatic plants, including tape-grass, the well-known Canadian waterweed, and frogbit. The family includes both freshwater and marine aquatics. They are found throughout the world in a wide variety of habitats, but are primarily tropical. Description The species are annual or perennial, with a creeping monopodial rhizome with the leaves arranged in two vertical rows, or an erect main shoot with roots at the base and spirally arranged or whorled leaves. The leaves are simple and usually found submerged, though they may be found floating or partially emerse. As with many aquatics they can be quite variable in shape – from linear to orbicular, with or without a petiole, and with or without a sheathing base. The flowers are arranged in a forked, spathe-like bract or between two opposite bracts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydrocharis Morsus-ranae
''Hydrocharis morsus-ranae L.'' is a species of the genus ''Hydrocharis'' known by the common name European frog-bit. It is a free-floating flowering plant that bears small white flowers. ''"Morsus-ranae"'' means "frog bite" in Latin, and it is part of this species' scientific name because frogs might seen as biting on the leaves. European frog-bit is often mistaken for an American frog-bit (''Limnobium spongia'') due to their similar looks and floating freely. It usually displays invasive behavior in Canada and North America, having a major impact on native ecosystems. However, European frog-bit is efficient in accumulating high concentrations of heavy metals and chemicals, removing waste from water. Description ''Hydrocharis morsus-ranae'' is a perennial plant with a stoloniferous growth, reaching a diameter of 0.1 to 1.5 meters. It forms individual rosettes ranging from 1 to 30cm. While mainly having separate male and female plants, it sometimes shows both sexes on different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aquatic Plants
Aquatic plants, also referred to as hydrophytes, are vascular plants and non-vascular plants that have adapted to live in aquatic environments ( saltwater or freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.Sculthorpe, C. D. 1967.

Hydrocharis Spongia
''Hydrocharis spongia'', commonly known as American frogbit, is a species of flowering plant in the family Hydrocharitaceae. It is native to the central and southeastern United States, where it grows in the Lower Mississippi Valley as far north as Illinois, and on the Southern Coastal Plain from Texas to Delaware.
