Abstract

Detached fertile scales and bracts of Glossopteris reproductive organs are described here. Eretmonia emarginata comb. nov., incorporating Stereocarpus emarginatus Surange, has been created. A new species of Glossotheca, G. immanis has also been described. The detached scales are referred to Glossopteris fructifications: Eretmonia, Glossotheca, Lidgettonia, Partha, Denkania, Dictyopteridium, Plumsteadiostrobus and Venustostrobus.
