Plants from the Permian and Triassic of Allan Nunatak, Victoria Land, East Antarctica, and Triassic plants from Mt Bumstead at the head of the Mill Glacier and from the Shackleton Glacier, are considered along with Jurassic plants from Carapace Nunatak. From the Permian,Glossopteris communisFeistmantel,G. cordataDana, andCistella strictaPlumstead are described; and from the Triassic,Dicroidium odontopteroides(Morris) Gothan,D. feistmanteli(Johnston) Gothan,D. dutoitiisp. nov., cf.Diplasiophyllum acutum(Walkom) Frenguelli, cf.“Johnstonia”trilobitaJones and de Jersey,Xylopteris elongata(Carruthers) Frenguelli, andRissikia media(Tenison Woods) Townrow. Jurassic plants areOtozamites antarcticusPlumstead,Nothodacrium warreniiTownrow,Masculostrobus warreniiTownrow, withTsugaepollenitescf.trilobatus(Balme) Dettmann, and an undescribed species ofBrachyphyllumBrongniart associated with pollen ofClassopollisPflug. It is concluded that the Jurassic plants are probably Middle Jurassic, the Triassic ones Upper or late Middle Triassic, and the Permian ones probably Upper Permian. Attention is drawn to the fact that to date there is no Lower Triassic flora known from Antarctica. The Allan Nunatak succession is compared with the Beardmore — Shackleton Glacier succession, and some similarities with the Tasmanian Triassic are pointed out.
