Rhizome wide-creeping, the scales + dense, ferrugineous, lanceolate, long- 

 acuminate, peltate at Ihe base. Stipes scattered, 10 — 50 c.M. long. Fronds 

 30—60 c.M. long, 15 — 40 c.M. broad, deltoid-lanceolate, 4— 5-pinnate. Lowest 

 pinnulae with oblong-rhomboidal divisions, the segments of which are entire 

 or deeply and finely inciso-pinnatifid with sharp teeth. Texture herbaceous; 

 surfaces naked; veins fine, blackish, 1 in each ultimate segment. Sori minute, 

 Solitary near the base of the segments, ± 2 — 6 to each tertiary division, 

 terminal on very short veinlets and therefore often apparently medial on the 

 ultimate veins; indusium broad, semiorbiciilar or subcordate.
