in a narrow dentate point; segments oolong, obtuse, slightly falcate and 

 dentate, 6 lines long by 2 lines broad, the sinus wide and rounded at 

 the base. Bhacliis proliferous. Veins pinnate ; venules simple, bear- 

 ing oblong and remote sori, the outer ends of which extend almost to 

 the margin of the segment. Indusium brown, entire, in the dry state 

 hard and recurved. 



This possesses the same form of frond, proliferous rhachis, and 

 venation as Deparia prolifera of Hooker. But the sori are in strict 

 conformity with species forming the present section of Asplenium.

Our specimen is more delicate in texture than the ordinary Euro-

 than in the plant represented at page 63 of Newman's British Ferns.
