Near (7. japonica LEUES., but differs from it by the more hairy fronds ; 

 still nearer (7. setosa (BEDD.) (BEDD. Fern. Br. Ind. t. 312 and Lastrea seiosa 

 BEDD. Fern. Brit. Ind. t. 262), from winch this differs by the oblong nearly 

 orbicular indusium with glanduliferous margin and by the very much smaller 

 fronds. Perliaps a smaller form of C. setosa.
