POLYPODIACEiE. 187 



Hab. Luzon, in the neighbourhood of Banos, Philippine Islands. 



Stipe slender, about a span long, nearly round, sidcate in front, 

 and covered with a short brown pubescence. Fronds membranaceous, 

 about 10 inches in length, of an oblong form, pinnate. Pinnae sessile, 

 alternate and divaricate, the inferior two pairs deflexed, linear-lanceolate, 

 acuminate, pinnatifid about half way down to the costa, the base 

 truncate-cuneate, the point entire for about half an inch. Segments 

 oblong, obtuse, slightly falcate. Rhachis, costa and veins hairy on both 

 sides with a short, brown pubescence. Sori large, arranged in a single 

 row about half-way between the costa and margin of the segments, 

 having a Iddney-shaped, hairy indusium. 



In many respects this is very closely related to the N. molle of 

 Schott. ; but it has a much smaller frond, a shorter and more slender 

 stipe, and narrower pinnae, the two inferior pairs considerably de- 

 flexed.
