A large number of impressions of Sphenopteris fronds are described from the Barakar Stage of South Karanpura Coalfield. Their study reveals that Sphenopteris polymorpha Feistm. (1881) and S. hughesi Arber (1905) are one and the same species. S. polymorpha Feistm. is emended and retained on the basis of nomenclatural priority.
