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. iSubdiuiorplia : Pinnae of fertile fronds distant, very narrow.
