Near D. truncata O. KtzE., but cliffere from it by the mucli more smooth 

 stipes and much more truncate lobes of the pinnpc. Also near Nephrodium 

 eusormn (Bedd. Fern. Brit. Ind. t. 130), but dififers from it by the less divided 

 or lobed pinnse and far much smaller form of the fronds. It beai-s some 

 rosemblance to Ncpli. extensum Blume Tar. minor (Bedd. Fem. Brit. Ind. t. 

 201), but distinguishable from it by the trimcately lobed pinna'.
