Rhizome short. Stipes approximate. Fronds 75-135 cm. long. Pinnae 

 2-3'/2 cm. broad, the lovver stalked, with the stalk winged by the nar- 

 rowly cuneate, dentate base of the pinna, the lowest whether or not 

 somewhat reduced ; suprabasal pinnae largest, 20—30 cm. long. Lobes straight 

 or somewhat falcate, the largest with ± 20 veins on a side; veins oblique, 

 straight or slightly curved, the lower strongly upcurved from a subhori- 

 zontal base, the lowest whether or not meeting in the sinus but not 

 anastomosing. Spores provided with small, roundish, tuberculiform or short, 

 irregularly ruguliform projections.
