PLATE XXXIX, 



Sphenopteris. Sp. 



A variety belonging to the elegant group of linear 

 ferng, of which Sphenopteris affinis and Sphenopteris linearis 

 may be regarded as the type. It is in some respects 

 not unlike Sphenopteris arguta ( u Fossil Flora/' Plate 

 CLXVIII.) We have unfortunately no information of 

 any kind respecting this beautiful specimen. 



Probably from Yorkshire. 



The Plate is reduced one-fourth of the original drawing.
