Rhizome not very wide-creeping. Stipes ± 60 c.M. long, dark-yellow, 

 smooth, clothed near the base with ovate, acuminate, broad, brown scales, 

 the rest sparingly scaly and hairy like the rachis. Fronds 35 — 40 c M. long, 

 ovate-oblong, + 15 c.M. broad, not narrowed towards the base. Pinnae erecto- 

 patent, 20 — 25 on each side, sessile, not adnate, 10 — 25 c.M. long, + \\ 

 c.M. broad, linear-lanceolate, caudate-acuminate, the point nearly entire, the 

 margin cut '/3-way down to the costa into numerous (+ 30 on each side), 

 truncate, coarsely crenate lobes + 5 m.M. broad. Texture flaccido-herbaceous ; 

 costae and main veins naked or slightly hairy; main veins pinnate in the 

 lobes; veins simple, the lower ones anastomosing. Sori medial on the veins; 

 indusium rudimentary, thin, fugacious, not rarely wanting.
