Arthrocnemum subterminale

Arthrocnemum subterminale (syn. Salicornia subterminalis) is a species of flowering plant in the Amaranth family known by the common name Parish's glasswort. This coastal and inland California native plant is a shrub that is found southerly into the northern states of Mexico, also in both coastal and inland areas, including salt marshes, alkali flats, and other habitats with saline soils.

As a halophyte, capable of growing in substrates with high salt concentrations, this glasswort is a perennial herb or subshrub growing in low clumps up to a meter wide mature plants having woody bases branching into fleshy, jointed green stems. The leaves appear as fused rings around stem, the tip of each individual blade narrowing to a point. The inflorescence is a fleshy, sticklike spike of minute flowers, each flower just a pocket made up of the joined sepals; there are no petals.
