Tetroncium is a genus of plants in the Juncaginaceae described as a genus in 1808. It contains only one known species, Tetroncium magellanicum, known from a few sub-Antarctic islands: Tierra Del Fuego (Chile and Argentina), Falkland Islands, and Gough Island.The plant got the name magellanicum because the original description was describing the sample found near the Strait of Magellan.
