My specimens of this plant, from the author, will be better 

 understood by the accompanying figures taken from them 

 than by words. The species has the characters in part of 

 Asplenium, of Diplazium, and Anisogonium ; and to those who 

 maintain those genera respectively, it would be difficult to 

 say to which of the three it has the strongest claim.
