Rhizome creeping or erect, scaly. Stipes 20 — 30 c.M. long, winged often 

 nearly or quite to the base. Fronds 60 — ^120 c.M. long, 30 — 60 c.M. broad, 

 cut down to a winged rachis into 3 — 8 pairs of entire, repand or sinuate 

 linear-oblong, acuminate laciniae 15 — 30 c.M. long, 2 — 6 c.M. broad, terminal 

 segment sintilar, the lowest ones often bifurcate. Texture herbaceous or 

 subcoriaceous ; surfaces naked; main veins distinct to the edge, connected by 

 copious areolae with free veinlets. Sori rather large, in 2 rows between the 

 main veins; indusiura persistent. — Resembling A, vaslum, Bl.
