Callitriche antarctica
Antarctic water-starwort is a small, mat-forming aquatic or wet-ground herb with tiny yellow flowers, native to cold subantarctic islands and southern South America. It needs cold, wet, open conditions and is not a typical garden or houseplant.
Callitriche antarctica, commonly known as the Antarctic water-starwort, is a small, prostrate plant with tiny yellow flowers in the family Plantaginaceae (though sometimes placed in its own family – Callitrichaceae). It is found in wet places on many subantarctic islands and has a wide circumantarctic distribution, something reflected in its specific epithet.
The starwort occurs on Campbell, Heard and Macquarie Islands, the Auckland, Antipodes, Kerguelen, Prince Edward, Crozet and Falkland Islands, as well as on South Georgia and Tierra del Fuego. The plant may be locally common, especially in boggy areas, along streams and around freshwater pools.
