Rhizome wide-creeping, woody, the scales lanceolate, dull-brown, deciduous. 

 Stipes 10 — 20 c.M. long, erect, slightly scaly below. Fronds 15 — 30 c.M. long, 

 5 — 8 c.M. broad, the point acute or acuminate, the edge entire, the base 

 rounded to decurrent. Texture firm-herbaceous; both surfaces naked; main

Rhizome creeping, blackish when dry, the scales adpressed, lanceolate, 

 brown, not dense. Stipes 5 — 20 m.M. apart, 7 — 40 c.M. long, the unwinged 

 portion often short, + scaly below, those of the fertile fronds the longest. 

 Fronds lanceolate, entire, 20 — 60 c.M. long, 4 — 12 c.M. broad, the apex acute, 

 the base gradually or rather suddenly decurrent, so as to form a long, narrow 

 wing to the stipe. Texture thin, herbaceous; surfaces naked; costa conspicu- 

 ous; main veins distinct to the edge; veins forming copious areolae with free 

 veinlets. Sori scattered irregularly, roundish or elliptical, often confluent.

 very gradually to both ends. Texture rigidly coriaceous; surfaces naked; 

 main veins zigzag, reaching 7* on the way to the edge; veins fine, hidden; 

 areolae copious, minute, with numerous free veinlets. Sori round, superficialj 

 crowded, filling up the upper 72 of ^3 of the frond, distinctly visible on the 

 upper surface.
