Rhizome short-creeping, the scales brown, somewhat crisped, subulate, 

 entire, filiform -acuminate. Stipes slender, 12 '/j — 25 cm. long, very 

 sparingly scaly towards the base, at length naked. Fronds subdeltoid- 

 ovate, + 9 — 25 cm. each way, the rachis naked. Pinnae 2 — 3 on each 

 side below the terminal one, very sparingly deciduously ciliolated; 

 terminal pinna elongate (ovate or lanceolate), 5 — 15 cm. long, 2 — 4 cm. 

 broad at the subtruncate-rotundate or subtruncate-cuneate base, acuminate) 

 the edge irregularly serrulate to toothed in the upper part., moderately 

 irregularly and shortly lobed in the lower part; lateral pinnae more or 

 less falcate, the higher subsessile, lanceolate-oblong, acuminate, irregularly 

 serrulate to twice serrate, or somewhat lobed and serrate, broadly cuneate 

 or rotundate-truncate at the base, smaller than the terminal one;
