BRITISH FERNS 



Fig. 74- A.f.f. Elworthii sphndens (pinna). 



E. splendens (Fig. 74). — A percristate form similar to Elworthii, 

 found in the same locality by the same finder ; but this has the 

 pinnules more acutely serrate, and is, therefore, more delicate- 

 looking. 



Excurrens (truncatum). — All terminals, even of the pinnules, 

 abruptly squared, and midrib projecting as a thorn.
