Echinodorus, commonly known as burhead[1] or Amazon sword,[citation needed] is a genus of plants in the family Alismataceae, native to the Western Hemisphere from the central United States to Argentina.[2][3] Its scientific name is derived from Ancient Greek echius – "rough husk" - and doros – "leathern bottle" - alluding to ovaries, which in some species are armed with persistent styles, forming prickly head of fruit. Some of the species are commonly cultivated in artificial aquatic habitats.
