Adders-tongue, and there is even a closer affinity 

 between the two species of the last-named Fern ; 

 but we have not considered it necessary to place 

 these three species amongst the ' Fern groups' 

 which we shall now proceed to describe. We 

 propose to follow pretty closely the order observed 

 by the botanists arranging the thirty-two Ferns 

 which we have yet to speak of in seven groups. 

 These we shall call the Polypodies, the Shield 

 Ferns, the Bladder Ferns, the Woodsias, the 

 Buckler Ferns, the Spleenworts, and the Filmy 

 Ferns.
