"The genus Atriplex, commonly called orache, atriplex or saltbush, of the family Chenopodiaceae (the goosefoot family), comprises nearly 200 species. The genus has a worldwide distribution, occurring on all continents except Antarctica. Most of the species are halophytes of coastal or inland saline habitats; a few are widespread ruderals of disturbed ground." (Bassett et al. 1983).
