Near Cystopteris /rayilis BERNH., but differs from it by the broader, shorter 

 fronds with more obtusely lobed pinnules. Also near (7. tennis (LowE Brit. 

 Exot. Fern. Yol. VH. p. 35) from which this differs by the triangular bipinnate 

 fronds ; from C. movpinensis (FRANCHET PI. DAYID. II. p. 149), this is separable 

 in the bipinnate (but not tripinnate) fronds.
