Khizome wide-creeping, wiry, clothed with long, crowded, deciduous, 

 ferrugineous hairs. Stipes scattered, wiry, + 7 — 10 cm. long, deciduously 

 long-hairy, 2-marginate towards the frond, the hairs ferrugineous. Fronds 

 4 — 5-pinnate towards the base, ovate, + 12 cm. long, 9 cm. broad, the 

 rachises winged, and beneath hairy like the stipe, the wings entire. 

 Pinnulae ovate or ovate-lanceolate, imbricate. Ultimate segments copious, 

 to 2'/j mm. long,' ± '/a i^™- broad, blunt at the apex, the edges hardly 

 crisped, remotely and shortly serrulate. Texture firm-membranaceous ; 

 surfaces naked; a central vein in each ultimate segment. Sori on short 

 lobes, occupying the anterior side of the pinnulae, near the base, at best 

 1 to a pinnule ; indusium oblong, the lower half narrowly obconical, 2- 

 marginate, longitudinally crested at the base, the upper half 2-valved, 

 the lobes subtriangular-oblong, entire or obsoletely repand; receptacle 

 included, columnar-filiform.
