44 species, see text Tecticornia is a genus of succulent, salt tolerant plants largely endemic to Australia.

The species of Tecticornia grow as annual or perennial herbs, subshrubs or small shrubs.

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.

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.
