The elongate crenate terminal leaflets offer a curious superficial resem- 

 blance in outline to the leaves or leaflets of some species of Asplenium (A . pinna- 

 tifidum Nutt. etc.) . In shape of leaves, length of petioles, habit of inflorescence, 

 number of capitula, proportionate length of exterior involucral bracts, and

various other respects, this species is sharply separate from B. Stokesii.
