Two additions to the moss flora of the South Shetland Islands in the maritime Antarctic
Tortella fragilis (Drumm.) Limpr. (Pottiaceae) and Bryum nivale Müll. Hal. (Bryaceae) are recorded for the first time from the South Shetland Islands in the northern maritime Antarctic. They were discovered in the Admiralty Bay area on King George Island, the largest island of this archipelago. The...
