Plant megafossils are described and illustrated from several localities and stratigraphic levels within the Ellsworth Mountains. The flora is dominated by various species of Glossopteris foliage and also includes sphenophyte stems and leaf sheaths, glossopterid reproductive organs, Gangamopteris leaves, and Vertebraria-type axes. The plants are preserved as impressions in fine-grained shale within the Polarstar Formation. Based on comparisons with other Antarctic and Gondwana floras, a Middle to Late Permian age is suggested.
