Stratiotes is a genus of submerged aquatic plant commonly known as water soldiers, [3] described as a genus by Linnaeus in 1753. [4] [5] Several specific names have been coined within the genus, but at present only one is recognized: Stratiotes aloides. native to Europe and NW Asia.
When referring to plants, the term describes land plants whose roots have adapted well to tolerate regular, prolonged submersion in water, as well as emergent and (occasionally) floating-leaved aquatic plants that are only partially immersed in water. Examples of semi-aquatic animals and plants are given below.
Fine-leaved water-dropwort is a hairless, annual to perennial herb about 150 cm tall. Young plants have tubers, which disappear by mid-summer.The stem is hollow and striated, normally about 1 cm in diameter but exceptionally reaching 8 cm, [2] erect or sprawling, rooting at the nodes of any submerged sections.
Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles. Most of these plant species are found either partially or fully submerged in their natural habitat. Although there are a handful of obligate aquatic plants that must be grown entirely underwater, most can grow ...
Nymphoides, or floatingheart, [1] is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface.
Ceratophyllum demersum, commonly known as hornwort (a common name shared with the unrelated Anthocerotophyta), rigid hornwort, [2] coontail, or coon's tail, [3] is a species of flowering plant in the genus Ceratophyllum. It is a submerged, free-floating aquatic plant, with a cosmopolitan distribution, native to all continents except Antarctica.
Stratiotes aloides, commonly known as water soldiers [2] or water pineapple, is a submerged aquatic plant native to Europe and northwestern Asia. In Britain it was once common in East Anglia and still is in many places, particularly wet ditches and healthy ponds. It is the only species in the genus Stratiotes.
In aquatic plants diffuse boundary layers (DBLs) around submerged leaves and photosynthetic stems vary based on the leaves' thickness, shape and density and are the main factor responsible for the greatly reduced rate of gaseous transport across the leaf/water boundary and therefore greatly inhibit transport of carbon dioxide.
