Rhizome erect or somewhat creeping. Fronds large, often 120— ISOcM. 

 long, 20—30 c.M. hroad. Pinnae very numerous, cut down ^j — '/j-way 

 towards the costa, the lower ones gradually reduced to hutterfly-like auricles 

 down the base of the stipe. Texture herbaceous; rachis and surfaces not 

 very hairy, often quite glabrous except the costae above ; veins 7 — 8 pair, the 

 2 — 3 lower pair anastomosing. Sori medial, generally on all the veins except 

 the 1 — 2 highest ones.
