184 0. Feistmantel — A sketch of the history of the [No. 3, 



Lindl. and Hutt., (Katrol group, Jabalpur group and Rajmahal group), 

 and Hymenopliyllites bunburyanus* Oldh. and Morr. sp. (Rajmahal 

 group). Of more importance is the following. 



Pecopteris lobata, Oldh. and Morr. 



1877. Pal. Gondwana Flora Vol. I, p. 92. 



1881. Rec. Geol. Survey India, Vols. XIV, p. 149, figures. 



This species I have quite recently united with DicJcsonia also. 

 Upper Gondwdnas : Bdjmahdl group in the Rajmahal hills. 



Order Polypodiaceae. 

 Type Asplenium, Lin. 

 Asplenium whitbyense, Heer. 

 1876-79. Pal. ind. Gondwana Flora, Vols. I and II. 

 1880. Pal. ind. Gondw. Flora, Vol. Ill, p. 52. 



This species was at first described as an Alethopteris, but the discovery 

 of specimens with fructification, caused it to be placed with Asplenium. 



Upper Gondwdnas : Umia group, Katrol group (Kach.) ; Jabalpur 

 group (Satpura and S. Rewah basin) ; Sripermatur (Vemdveram) group. 



Lower Gondwdnas : Raniganj group, Raniganj coalfield ; Jharia coal- 

 field ; S. Rewah basin. To this very probably also belongs : 



Alethopteris^ indica, Oldh. and Morris. 

 1862-79. Pal. ind. Gondwana Flora Vol. I. 

 Upper Gondwdnas : Jabalpur group (S. Rewah basin); Sripermatur 

 group (Sripermatur area ; S. Kistna area ; Utatur plant beds) ; Bdjmahdl 

 group. 



Alethopteris medlicottiana,% Feistm. 

 1877. Pal. ind. Gondwana Flora, Vol. IX, p. 87. 

 This form has probably also to be classed with this group. 

 Upper Gondwdnas : Jabalpur group (Satpura aud S. Rewah basin). 



Type Polypodium, Linn. 

 Alethopteris lindleyana,§ Royle. 

 1869. Royle, I. c, Tab. II, fig. 4. 



Although the appearance of the fronds would place this form in proxi- 

 mity with Aspl. whitbyense and Asp) I. indicum, yet, fructificating specimens, 



* 1877. Pal. ind. ib. p. 88. 



f Alethes (gr) = true, and pteris = true fern.
