Rhizome wide-creeping, stout, the scales minute, lanceolate, castaneous. 

 Stipes slender, brown, naked, + 30 c.M. long. Fronds lanceolale-deltoid, 

 3-pinnatifid, + 45 c.M. long. Pinnae suhsessile, ;icuminate, the lowest the 

 longest, lanceolale-deltoid, the highest lanceolate. Lower pinnulae lanceolate, 

 sessile, deeply pectinato-pinnatifid. Lobes distant, ereclo-patejit, inequilateral, 

 lanceolate. Texture firm; surfaces naked: rachis sparingly scaly; veins 1 to 

 each lobe. Sori small, subterminal ; indusium firm, cuneate, as long as broad.

Rhizome stout, creeping; scales dense, linear-lanceolate, ferrugineous, 

 the base + dilated, peltate, the point long, linear-subulate, crisped, interlaced, 

 short-ciliate, giving the rhizome a woolly appearance. Stipes firm, naked, 

 10—50 c.M. long. Fronds 30—60 c.M. long, 15—40 c.M. broad, deltoid to 

 ovate-lanceolate, 3 — 4-pinualifid; main rachis slightly winged towards the 

 apex. Pinnulae of the lower pinnae + S'/j c.M. broad, deltoid-lanceolate, 

 cut down to the rachis in the lower part with oblong-deltoid, more or less 

 deeply toothed segments, wich are obliquely cuneate at the base. Texture
