This is assuredly the most elegant of the genus Davallia, 

 so narrow in its segments that they seem to be composed 

 of the midrib with a very narrow herbaceous margin. The 

 apices of the fertile segments which are very copious have the 

 appearance of being unequally 2-lipped : the segment itself 

 being much dilated, and the involucre, an oblong or tongue- 

 shaped scale, is appressed to it, quite concealing the sorus 

 or cluster of capsules in its axis.
