Sori round, placed in 1—4 rows on each side of th^ midrib. Indusium

Rhizome oblique, decumbent. Stipes not articulate to the rhizome. Fronds 

 pinnate; pinnae articulate to the rachis; veins free, erecto-patent, forked or 

 branched, bearing the sori dorsal or sometimes terminal. Diels, in Engl. &

Rhizome strong; the scales subulate, dense. Stipes approximate or scat- 

 tered, 10—30 c.M. long, fibrillose at the base. Fronds 60—100 c.M. long, 

 20 — 30 c.M. broad, oblong, acuminate, simply pinnate. Pinnae close, articulate, 

 not rarely contiguous, sessile or subsessile, 1^2 c.M. broad, + falcate, acute 

 or acuminate, the edge nearly entire, the base truncate or cordate. Texture 

 papyraceo-herbaceous or subcoriaceous ; surfaces naked; rachis more or less 

 scaly ; veins pinnate, the lower ones ending short from the margin. Sori in 

 1 — 4 rows on each side, the inner row the most constant and regular, often 

 close to the midrib or nearly so. 



Var. crenata : Superior base of the pinnae. broadly cuneate, lower 

 one variable. 



Var. jinbclimorpha : Pinnae of fertile fronds distant, very narrow. 



War. HLingii: Small form. Pinnae blunt, the base bluntly rounded. 

 Sori in 1 row.
