POLYPODIACE/E. 



Near D. truncata O. KTZE., but differs from it by the much more smooth?! 

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

 eusorum (BEDD. Fern. Brit. Ind. t. 130), but differs from it by the less divided 

 or lobed pinnae and far much smaller form of the fronds. It bears some 

 resemblance to NepJi. extensum BLUME var. minor (BEDD. Fern. Brit. Ind. t| 

 201), but distinguishable from it by the truncately lobed pinnae.
