Tetroncium

Tetroncium is a genus of plants in the Juncaginaceae described as a genus in 1808.^[2][3] 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.^[1][4][5][6] The plant got the name magellanicum because the original description was describing the sample found near the Strait of Magellan.^[7]
