Ceratopteris is a fairly popular aquarium plant, often sold under the name "water sprite." It may be grown as an emersed but natant (floating) plant, or as an immersed plant rooted in the substrate. Under the right conditions the plants will grow fully emerse erect leaves.
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.
Neustons can be informally separated into two groups: the phytoneuston, which are autotrophs floating at the water surface including cyanobacteria, filamentous algae and free-floating aquatic plant (e.g. mosquito fern, duckweed and water lettuce); and the zooneuston, which are floating heterotrophs such as protists (e.g. ciliates) and metazoans ...
Other notable invasive plant species include floating pennywort, [58] Curly leaved pondweed, [57] the fern ally Water fern [57] and Parrot's feather. [59] Many of these invasive plants have been sold as oxygenating plants for aquaria or decorative plants for garden ponds and have then been disposed of into the environment. [57]
The plant spreads by the rosettes and fruits detaching from the stem and floating to another area on currents or by fruits clinging to objects, and animals. The unrelated Eleocharis dulcis is also called a water chestnut. [2] It is an aquatic plant, a sedge, whose round, crisp-fleshed corms are common in Chinese food.
Riccia fluitans, the floating crystalwort, [3] is an aquatic floating plant of the liverwort genus Riccia which is popular among aquarists as a retreat for young fry and is used in live-bearing tanks. It can be found floating in ponds, and often forms thick mats on and under the water surface. It normally grows quickly at the surface.
Glyphosate applied to floating leaves after emergence during late spring or summer has been used as a chemical control for N. peltata. [18] Nonetheless, repeated applications are necessary, [18] and spraying floating leaves shows 40-50% control for a single season. [3] Dichlobenil is more effective than glyphosate in controlling N. peltata. [3]
Wolffia are free-floating aquatic plants with fronds that are nearly spherical to cylindrical in shape and lack airspaces or veins. [1] [3] They do not have roots. [1]Their rarely seen flowers originate from a cavity on the upper surface of the frond, and each flower has one stamen and one pistil.
