In 1849 Professor J. D. Dana described certain leaves from the Illawarra District and Newcastle, New South Wales, occurring in the Upper Coal-measures. To these he gave the name of Noeggerathia spathulata and N. media. Long after, in 1879 to be exact, Dr. O. Feistmantel established his genus Noeggerathiopsis for the reception of similar leaves from the Talchir-Kararbari Beds of the Lower Gondwana System, and from his remarks it may, by inference, be concluded that Dana's were included in the new genus also. This inference is justified by Feistmantel's later definite reference of these leaves to Noeggerathiopsis; at the same time he added another species, N. prisca, from the Lower Coal-measures at Greta. He believed them to be closely allied with Cycadeaceae.
