Collections of three fossil floras have been made recently by the British Antarctic Survey. They include Lower Permian material from the Theron Mountains, Coats Land, Antarctic Mainland, Mid-Upper Triassic material from Livingston Island in the South Shetlands and Tertiary material from King George Island in the South Shetlands. Each collection is described in detail systematically and is discussed with reference to its composition, comparison with other floras, age and possible palaeoenvironment.
