Tecticornia is a genus of succulent, salt tolerant plants largely endemic to Australia. Taxa in the genus are commonly referred to as samphires. [1] In 2007, the genus Halosarcia, along with three other Australian genera (Pachycornia, Sclerostegia and Tegicornia) was incorporated into the genus.

The species of Tecticornia grow as annual or perennial herbs, subshrubs or small shrubs. Stems are branched, glabrous and appear jointed. The opposite leaves are fleshy, glabrous, connate in the lower part and cup-like or collar-like stem-clasping, with minute (0–3 mm long) two-lobed to triangular leaf blades. [2]

The spike-shaped inflorescences consist of opposite bracts, mostly connate and stem-clasping, free in some species. Their blades are cup- or collar-like or deltoid to semi-circular scales. In the axil of each bract, there are three to five (rarely one or seven) flowers, free or sometimes fused to each other, to the bract, and to the inflorescence axis. The flowers are hermaphrodite, rarely unisexual. They consist of a 2-3-lobed perianth of connate tepals, one stamen, and an ovary with two stigmas. [2]

In fruit, the perianth remains membranous or becomes crustaceous, spongy, or horny. The fruit wall (pericarp) may be membranous, fleshy, crustaceous, or woody. The seed is disc-shaped or wedge-shaped, its seed coat with smooth or reticulate, tuberculate or longitudinally ribbed surface. The seed contains the curved embryo and copious perisperm (feeding tissue). [2]

Distribution

All species of Tecticornia are distributed in Australia. Only one species, Tecticornia indica (Syn. Halosarcia indica, Arthrocnenum indicum) has a wider range outside this continent along the tropical coasts of the Indian Ocean to eastern and western tropical Africa. [2]

Systematics

The first publication of Tecticornia was made in 1880 by Joseph Dalton Hooker. [3] The type species of this genus is Tecticornia cinerea(F. Muell.) Baill, [4] which is a synonym of Tecticornia australasica . Tecticornia used to be a small genus with just three species, until in 2007, the genera Halosarcia, Pachycornia, Sclerostegia and Tegicornia were included. [5]

Phylogenetical research of the subfamily Salicornioideae revealed that the Tecticornia/Halosarcia/Pachycornia/Sclerostegia/Tegicornia lineage is a sister group of Sarcocornia/Salicornia . [2]

In 2016, Tecticornia comprises about 44 species, [6] eleven species were described recently. [7] [8] [9] [10] [11] [12] (distributions as given by Australian Plant Census (2008). [6]

Uses

Young twigs of Tecticornia indica can be cooked and eaten as a vegetable. In Madagascar, they are pickled in vinegar and used as a spice. [17]

<i>Salicornia</i> Genus of flowering plants in the family Amaranthaceae

Salicornia is a genus of succulent, halophyte flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. Salicornia species are native to North America, Europe, South Africa, and South Asia. 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 "titines 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, usually as 'sea beans' or samphire greens or sea asparagus.

Samphire

Samphire is a name given to a number of succulent salt-tolerant plants (halophytes) that tend to be associated with water bodies.

<i>Sarcocornia</i>

Glasswort list of plants with the same or similar names

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.

<i>Atriplex cinerea</i> Species of plant

To others, it is called “saltwort.” It grows in various zones of intertidal salt marshes, on beaches, and among mangroves.
