Saltwort

Saltwort, a name strictly applied to Salsola Kali, a British seaside plant belonging to the order Chenopodiaceae, but often extended to the allied genus Salicornia. They take the name from growing upon "saltings," and were formerly largely used III the preparation of the ash known as barilla, an impure sodium carbonate used in the manufacture of glass and of soap, but now in the main superseded by the introduction of soda made from common salt.
