Tecticornia is a genus of
In 2007, the genus Halosarcia, along with three other Australian genera (Pachycornia, Sclerostegia and Tegicornia) was incorporated into the genus.Description

The species of Tecticornia grow as annual or
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]

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]
