Yery near Asplenium ensiforme WALL. (HooK. et GE. Ic. Fil. t. 71) and 

 Asplenium apoense COPELAND, but differs from them by the entire involucres 

 and in having fronds which are sometimes 2-4-lobed at the apex. The sori 

 of this fern are usually of the Asplenium-ijpe, but sometimes are of the 

 Diplazium-or Scolopendrium-iype.
