saltwort

Salsola kali is the restored botanical name for a species of flowering plants in the amaranth family that has been treated as Kali turgidum. It is native to Macaronesia, and from the Atlantic coasts of Europe to the Baltic Sea and the Mediterranean (although it has been introduced elsewhere). It is an annual plant which grows primarily in the temperate biome, in salty sandy coastal soils. It is commonly known as prickly saltwort or prickly glasswort.

In dry inland places it is replaced by Salsola tragus (syn. Kali tragus or Salsola kali subsp. tragus), which is less tolerant to salty soils, and has spread more widely from Eurasia to other continents. Salsola kali is less widespread as an introduced species in America.
