AbstractSeven species are reported here for the first time for South Georgia. Two of these were already known from Tierra del Fuego,Acrolophozia fuegianaSchust. andMarsupella sprucei(Limpr.) H. Bern., butAcrolophozia sulcataHässel,Marsupella austrogeorgicaHässel, andMarsupella minutulaHässel are described as new. The additional two species which are described,Austrolembidium crassumHässel andGreeneothallus gemmiparusHässel, also required the creation of two new genera. The total number of liverwort species now known to be present on South Georgia is sixty-six.
