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.
