The size and outline of this Fern is normal, sometimes, 

 however, as in the Oldstead examples, being widest at the 

 centre of the frond. 



The margin (and more especially in the upper portion) is 

 distinctly crenato-lobate, and occasionally sub-undulated. 



Sori abundant and prominent beneath, and distinctly supra- 

 soriferous above, the latter often large. 



Length of frond from twelve to fifteen inches. 



The specimen illustrated was found at Oldstead, Yorkshire, 

 and communicated by Mr. C. Monkman, of IMalton.
