Feistmantel has distinguished as G. major some spathulate leaves 

 in which the basal portion is longer and narrower than in the 

 commoner examples of this genus, and has comparatively few 

 nerves (Text -fig. 21b). These differences appear to me to be 

 hardly sufficient to warrant specific rank ; the frond in other 

 respects, especially in its general nervation, being closely similar 

 to the more lanceolate forms of G. cyclopteroides (cf. Feistmantel 

 (79 1 ), pi. xiv, fig. 1). Feistmantel has compared these leaves with 

 McCoy's G. spatulata. This variety is known from the Karharbari 

 and Talchir Series in India, and from the Permian of Russia.
