The sea beet, "Beta vulgaris" subsp. "maritima" ((L.) Arcangeli.), is a member of the family Amaranthaceae, previously of the Chenopodiaceae. Carl Linnaeus first described "Beta vulgaris" in 1753; in the second edition of "Species Plantarum" in 1762, he divided the species into wild and cultivated varieties, giving the name "Beta maritima" to the wild taxon. The sea beet is native to the coasts of Europe, northern Africa, and southern Asia.
