Suaeda is a genus of plants also known as seepweeds [1] and sea-blites. Most species are confined to saline or alkaline soil habitats, such as coastal salt-flats and tidal wetlands. Many species have thick, succulent leaves, a characteristic seen in various plant genera that thrive in salty habitats (halophile plants).
There are about 110 species in the genus Suaeda. [2]
The most common species in northwestern Europe is S. maritima. It grows along the coasts, especially in saltmarsh areas, and is known in Britain as "common sea-blite", but as "herbaceous seepweed" in the USA. It is also common along the east coast of North America from Virginia northward. One of its varieties is common in tropical Asia on the land-side edge of mangrove tidal swamps. Another variety of this polymorphic species is common in tidal zones all around Australia (Suaeda maritima var. australis is also classed as S. australis). On the coasts of the Mediterranean Sea a common Suaeda species is S. vera. This is known as "shrubby sea-blite" in English. It grows taller and forms a bush.
The name Suaeda comes from an oral (non-literary) Arabic name for the Suaeda vera species transliterated as suaed, sawād or suēd, [3] and it was assigned as the genus name by the 18th century taxonomist Peter Forsskål during his visit to the Red Sea area in the early 1760s. [2] [4] Forsskål's book, Flora Aegyptiaco-Arabica, published 1775, in Latin, declares Suæda as a newly created genus name, with the name taken from an Arabic name Suæd and presents the species members of the new genus. [5]
The genus includes plants using either C3 or C4 carbon fixation. The latter pathway evolved independently three times in the genus and is now used by around 40 species. S. aralocaspica, classified in its own section Borszczowia, uses a particular type of C4 photosynthesis without the typical "Kranz" leaf anatomy. [6] [7] [8]
In the medieval and early post-medieval centuries suaeda was harvested and burned, and the ashes were processed as a source for sodium carbonate for use in glass-making; see glasswort.
In Mexico, some species such as Suaeda pulvinata, called romeritos, are cooked in a traditional festive dish called either revoltijo or romeritos . It is also eaten as wild greens (quelites), or as edible herbs grown as part of the crop-growing system called milpa.
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus Amaranthus. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales.
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl was a Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus.
The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included – together with other subfamilies – in the family Chenopodiaceae, or goosefoot family, in the Cronquist system.
Chenopodium is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoot, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus Chenopodium is the namesake member of the subfamily Chenopodioideae.
The sea beet, Beta vulgaris subsp. maritima, is a member of the family Amaranthaceae native to the coasts of Europe, northern Africa, and southern Asia.
British NVC community SM10 is one of the salt-marsh communities in the British National Vegetation Classification system. This community is found in coastal areas in the Solway Firth, south Cumbria, Lancashire, west and south Wales, Hampshire, The Wash and north Lincolnshire. There are no subcommunities.
Utricularia inflexa is a medium to large sized suspended aquatic carnivorous plant that belongs to the genus Utricularia. It is probably a perennial plant. U. inflexa is endemic to Africa and the Indian subcontinent.
Suaeda australis, the austral seablite, is a species of plant in the family Amaranthaceae, native to Australia. It grows to 10 to 90 cm in height, with a spreading habit and branching occurring from the base. The leaves are up to 40 mm in length and are succulent, linear and flattened. They are light green to purplish-red in colour.
Suaeda esteroa is a species of flowering plant in the family Amaranthaceae known by the common name estuary seablite. It is a yellow-green to reddish subshrub with fleshy, succulent leaves. It is native to the estuaries and salt marshes of coastal southern California and Baja California.
Suaeda aralocaspica is a species of plant in the family Amaranthaceae that is restricted to the deserts of Central Asia. It is a halophyte and uses C4 carbon fixation but lacks the characteristic leaf anatomy of other C4 plants (known as kranz anatomy). Carrying out complete C4 photosynthesis within individual cells, these plants instead are known as single‐cell C4 system or SCC4 plants. This makes them distinct from typical C4 plants, which require the collaboration of two types of photosynthetic cells. SCC4 plants have features that make them potentially valuable in engineering higher photosynthetic efficiencies in agriculturally important C3 carbon fixation species such as rice. To address this, the 467 Mb genome of S. aralocaspica has been sequenced to help understanding of the evolution of SCC4 photosynthesis and contribute to the engineering of C4 photosynthesis into other economically important crops.
Suaeda calceoliformis is a species of flowering plant in the family Amaranthaceae known by several common names, including Pursh seepweed and horned seablite.
Suaeda californica is a rare species of flowering plant in the amaranth family known by the common name California seablite. It is now endemic to San Luis Obispo County, California, where it is known from a few occurrences in the marshes around Morro Bay, historical populations around San Francisco Bay have been extirpated.
Suaeda nigra, often still known by the former name Suaeda moquinii, is a species of flowering plant in the amaranth family, known by the vernacular names bush seepweed or Mojave sea-blite.
The Suaedoideae are a subfamily of plants in the family Amaranthaceae.
Suaeda vera, also known as shrubby sea-blite, shrubby seablight or in the USA sometimes as alkali seepweed, 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.
Suaeda maritima is a species of flowering plant in the family Amaranthaceae known by the common names herbaceous seepweed and annual seablite.
Galium paschale is a species of flowering plant in the genus Galium found in south-eastern Europe and Turkey.
Aber Taf is a large Site of Special Scientific Interest (SSSI) in Carmarthenshire, Wales, and forms part of the Carmarthen Bay and Estuaries Special Area of Conservation.
Suaeda pulvinata is an endemic seepweed from Mexico. It lives in the shores of Lake Texcoco and Lake Totolcingo. It lives underwater as an aquatic plant for half of the year and on dry land as a terrestrial plant for the other half due to the changing levels of the lakes that it inhabits. It is a perennial flat herb with prostrate stems. Its leaves and inflorescences are green to reddish in color.
Cleome angustifolia, known as golden cleome, yellow cleome or yellow mouse whiskers, is an African species of plant in the Cleomaceae family. It is common along roadsides and in disturbed areas and is eaten as vegetable locally. Swedish naturalist Peter Forsskål described C. angustifolia in 1775. It is one of three species in genus Cleome (the others being C. gynandra and C. oxalidea) that independently acquired the C4 pathway of carbon fixation. A species close to C. angustifolia, Cleome paradoxa, is C3–C4 intermediate.
