Salicornia is a

halophytic (salt tolerant) 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.[1] To French speakers in Atlantic Canada
, they are known colloquially as titines de souris ('mouse tits'). 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.

Description

Illustration of Salicornia maritima

The Salicornia species are small annual herbs. They grow prostrate to erect, their simple or branched stems are succulent, hairless, and appear to be jointed. The opposite

leaves are strongly reduced to small fleshy scales with a narrow dry margin, hairless, unstalked and united at the base, thus enclosing and forming a succulent sheath around the stem, which gives it the appearance of being composed of jointed segments.[2]: 522 [3]
Many species are green, but their foliage turns red in autumn. Older stems may be somewhat woody basally.

All stems terminate in spike-like apparently jointed

cyme tightly embedded in cavities of the main axis and partly hidden by the bracts. The flowers are arranged in a triangle, both lateral flowers beneath the central flower. The hermaphrodite flowers are more or less radially symmetric, with a perianth of three fleshy tepals united nearly to the apex. There are 1–2 stamens and an ovary with two stigmas.[3]

The perianth is persistent in fruit. The fruit wall (pericarp) is membranous. The vertical seed is ellipsoid, with yellowish brown, membranous, hairy seed coat. The seed contains no

perisperm (feeding tissue).[3]

Like most members of the subfamily Salicornioideae, Salicornia species use the C3 carbon fixation pathway to take in carbon dioxide from the surrounding atmosphere.[4]

Taxonomy

Salicornia europaea

The genus Salicornia was first described in 1753 by Carl Linnaeus.[5] Salicornia europaea was selected as the type species.[6]

The genus probably originated during the

paraphyletic),[7] the annual, strongly inbreeding and frost-tolerant Salicornia diversified during the late Pliocene to early Pleistocene. By events of intercontinental dispersals, they reached southern Africa twice and North America at least three times. Two tetraploid lineages expanded rapidly, with the ability to colonize lower belts of the salt marshes than their diploid relatives. Inbreeding and geographical isolation led to a large number of reproductive isolated species that are only weakly differentiated.[8]

The taxonomic classification of this genus is extremely difficult (with one paper calling it a "taxonomic nightmare").[8] The determination of species seems almost impossible for non-specialists. The reasons for these difficulties are the reduced habit with weak morphological differentiation and high phenotypic variability. As the succulent plants lose their characteristics while drying, herbarium specimens often cannot be determined with certainty and are less suited for taxonomic studies.[8]

Molecular phylogenetic studies have regularly revised the circumscription of the genus. It was considered distinct from Sarcocornia in 2007 and 2012 studies.[8][9] A 2017 study resulted in Sarcocornia being sunk into Salicornia, substantially increasing the size of the genus, which was divided into four subgenera.[7]

Species

As of April 2022, Plants of the World Online accepted the following species:

Distribution and habitat

Salicornia at Ballona Wetlands, Southern California

The species of Salicornia are widely distributed over the Northern Hemisphere and in southern Africa, ranging from the subtropics to subarctic regions. There is one species present in New Zealand.[10]

They grow in coastal salt marshes and in inland salty habitats like shores of salt lakes.[8] Salicornia species are halophytes and can generally tolerate immersion in salt water (hygrohalophytes).

Ecology

Salicornia species are used as food plants by the larvae of some Lepidoptera species, including the Coleophora case-bearers C. atriplicis and C. salicorniae; the latter feeds exclusively on Salicornia spp.

Uses

Culinary

Salicornia bigelovii

S. europaea is edible, either cooked or raw,

rock samphire); the term samphire is believed to be a corruption of the French name, [herbe de] Saint-Pierre, which means "St. Peter's herb".[13]

In Hawaii, where it is known as 'sea asparagus', it is often blanched and used as a topping for salads or accompaniment for fish.[14][15]

In addition to S. europaea, the seeds of

saponins, which are toxic under certain conditions.[11]

Umari keerai (S. brachiata) is cooked and eaten or pickled. It is also used as fodder for cattle, sheep and goats.[16] In Kalpitiya, Sri Lanka, it is used to feed donkeys.

On the east coast of Canada, the plant is known as 'samphire greens' and is a local delicacy. In southeast Alaska, it is known as beach asparagus. In Nova Scotia, Canada, they are known as crow's foot greens. In British Columbia, they are known as sea asparagus.[17] In the United States, they are known as 'sea beans' when used for culinary purposes. Other names include sea green bean, sea pickle, and marsh samphire.[18]

In India, researchers at the Central Salt and Marine Chemicals Research Institute developed a process to yield culinary salt from S. brachiata. The resulting product is known as vegetable salt and sold under the brand name Saloni.[19]

Dehydrated, pulverized Salicornia is sold under the brand name "Green Salt" as a salt substitute claimed to be as salty in taste as table salt, but with less sodium.[20][21]

Pharmacological research

In South Korea, Phyto Corporation has developed a technology of extracting low-sodium salt from S. europaea, a salt-accumulating plant. The company claims that the naturally derived plant salt is effective in treating

antioxidative and antithrombus polyphenols, claimed to be effective in treating obesity and arteriosclerosis,[24] as well as providing a means to help resolve global food shortages.[25]

Environmental uses

volatilization rates 10–100 times higher than other species.[27]

Industrial use

Historical

The ashes of

LeBlanc process
for industrial production of soda ash superseded the use of plant sources in the first half of the 19th century.

Umari keerai is used as raw material in paper and board factories.[16]

Contemporary

Because S. bigelovii can be grown using saltwater and its seeds contain high levels of unsaturated

shrimp farming) is a suggested use for this purpose.[28]

Experimental fields of Salicornia have been planted in Ras al-Zawr (

Bahia de Kino.[33]

Stems and roots of S. brachiata plants have a high cellulose content (ca. 30 wt. %), whereas tender stem tips exhibit a low cellulose content (9.2 wt. %).[34] S. brachiata revealed the dominance of rhamnose, arabinose, mannose, galactose, and glucose, with meager presence of ribose and xylose in their structural polysaccharide.[35]
