A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes. An example of a halophyte is the salt marsh grass Spartina alterniflora. Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in the halophyte database.
Sodium carbonate is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield alkaline solutions in water. Historically, it was extracted from the ashes of plants grown in sodium-rich soils, and because the ashes of these sodium-rich plants were noticeably different from ashes of wood, sodium carbonate became known as "soda ash". It is produced in large quantities from sodium chloride and limestone by the Solvay process, as well as by carbonating sodium hydroxide which is made using the chloralkali process.
Crithmum is a monospecific genus of flowering plant in the carrot family, Apiaceae. The sole species, Crithmum maritimum, is commonly known as rock samphire, sea fennel or samphire. It is found in parts of the Old World and is edible.
Salicornia is a genus of succulent, halophytic flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. Salicornia species are native to North America, Europe, central Asia, and southern Africa. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in Salicornia. To French speakers in Atlantic Canada, they are known colloquially as tétines de souris. The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus as sea beans, samphire greens or sea asparagus.
Samphire is a name given to a number of succulent salt-tolerant plants (halophytes) that tend to be associated with water bodies.
Saltwort is a common name for various genera of flowering plants that thrive in salty environments, typically in coastal salt marshes and seashores, including:
Soda inermis, the opposite-leaved saltwort, oppositeleaf Russian thistle, or barilla plant, is a small, annual, succulent shrub that is native to the Mediterranean Basin. It is a halophyte that typically grows in coastal regions and can be irrigated with salt water. The plant was previously classified as Salsola soda, now regarded as a synonym.
Salsola kali is the restored botanical name for a species of flowering plants in the amaranth family. It is native to the Northern African and European Atlantic coasts to the Mediterranean. It is an annual plant which grows primarily in the temperate biome.
Barilla refers to several species of salt-tolerant (halophyte) plants that, until the 19th century, were the primary source of soda ash and hence of sodium carbonate. The word "barilla" was also used directly to refer to the soda ash obtained from plant sources. The word is an anglicization of the Spanish word barrilla for saltwort plants.
The glassworts are various succulent, annual halophytic plants, that is, plants that thrive in saline environments, such as seacoasts and salt marshes. The original English glasswort plants belong to the genus Salicornia, but today the glassworts include halophyte plants from several genera, some of which are native to continents unknown to the medieval English, and growing in ecosystems, such as mangrove swamps, never envisioned when the term glasswort was coined.
Salicornia quinqueflora, synonym Sarcocornia quinqueflora, commonly known as beaded samphire, bead weed, beaded glasswort or glasswort, is a species of succulent halophytic coastal shrub. It occurs in wetter coastal areas of Australia and New Zealand.
Tecticornia pergranulata is a succulent halophytic plant species in the family Chenopodiaceae, native to Australia. This plant is commonly tested in labs involving its C3 photosynthesis and its unique resistance to salinity and adversity.
Salicornia bigelovii is a species of flowering plant in the family Amaranthaceae known by the common names dwarf saltwort and dwarf glasswort. It is native to coastal areas of the eastern and southern United States, Belize, and coastal Mexico. It is a plant of salt marshes, a halophyte which grows in saltwater. It is an annual herb producing an erect, branching stem which is jointed at many internodes. The fleshy, green to red stem can reach about 60 cm in height. The leaves are usually small plates, pairs of which are fused into a band around the stem. The inflorescence is a dense, sticklike spike of flowers. Each flower is made up of a fused pocket of sepals enclosing the stamens and stigmas, with no petals. The fruit is an utricle containing tiny, fuzzy seeds. The southern part of the species range is represented by the Petenes mangroves of the Yucatán, where it is a subdominant plant associate in the mangroves.
Salicornia virginica is a halophytic perennial dicot which grows in various zones of intertidal salt marshes and can be found in alkaline flats. It is native to various regions of the Northern Hemisphere including both coasts of North America from Canada to Mexico.
Juncus roemerianus is a species of flowering plant in the rush family known by the common names black rush, needlerush, and black needlerush. It is native to North America, where its main distribution lies along the coastline of the southeastern United States, including the Gulf Coast. It occurs from New Jersey to Texas, with outlying populations in Connecticut, New York, Mexico, and certain Caribbean islands.
Batis maritima, the saltwort or beachwort, is a halophyte. It is a C3-plant, long-lived perennial, dioecious, succulent shrub. The plant forms dense colonies in salt marshes, brackish marshes, and mangrove swamps and frequently is found on the margins of saltpans and wind-tidal flats. Batis maritima is a pioneer plant, covers quickly areas where hurricanes have destroyed the natural vegetation.
Suaeda fruticosa is a species of flowering plant in the family Amaranthaceae. It is a small shrub, with very variable appearance over its wide range. It is a halophyte, and occurs in arid and semi-arid saltflats, salt marshes and similar habitats.
Arthrocaulon macrostachyum, synonym Arthrocnemum macrostachyum, is a species of flowering plant in the amaranth family. It is native to coastal areas of the Mediterranean Sea and the Red Sea and parts of the Middle East, where it grows in coastal and inland salt marshes, alkali flats, and other habitats with saline soils.
Salicornia pacifica, also known as pickleweed, sea asparagus, Pacific swampfire, or glasswort, is a species of low-growing perennial succulent halophyte in the genus Salicornia found in the Pacific coast of North America and California.
Salicornia fruticosa, synonym Sarcocornia fruticosa, is a species of glasswort in the family Amaranthaceae (pigweeds). It is native to southern Europe, north Africa, Western Asia and Yemen. It is a halophyte, a plant that can grow in saline conditions.
