Fredda D. Reed was one of the first students of Adolph Noé and was responsible for some of the early work on Carboniferous coal-ball plants in North America. As a faculty member for 35 years at Mount Holyoke College, she touched the lives of generations of students through her strong work ethic, tenacity for detail, and unending sense of humor.

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.
