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.
