 and irregularly crenate to toothed at the margin, sometimes once forked, the 

 stipes varying from short to 6 c.M. long, often slightly winged. Texture co-

Rhizome wide-creeping, the scales dense, with an oblong, peltate, ad- 

 pressed base and a long, linear-subulate, recurved or spreading, shortly ciliate 

 or finely toothed point. Stipes 1 — 4'/2 c.M. long, 1 — 3 c.M. apart. Fronds 

 dimorphous, the barren ones lanceolate, 6 — 16 c.M. long, 1 '/j — 3'/j c.M. 

 broad, the apex acute, the edge entire or slightly crenate, the base more or 

 less suddenly narrowed or rounded and then often decurrent so as to^orm 

 a long, narrow wing to the stipe. Cexture coriaceous, rigid; surfaces naked; 

 veins commonly once or more times forked. Fertile fronds narrower, deeply 

 pinnatifid into blunt, entire or broadly toothed lobes 3 — 4 m.M. broad. Sori 

 2 — 10 to a lobe, often close; indusium transversally oblong. 



War. nervosa: Fronds crisped; veins more conspicuous.
