Rhizome firm, short-creeping, the scales linear-lanceolate, squarrose, brown-

 c.M. long, either simple, lanceolate, 1 — 4 c.M. broad, or 3-fid with the lateral 

 lobes erecto-patent, similar to the terminal one but smaller, or the fronds pin- 

 natifid with 2 — 4 pairs of lateral lobes below the terminal one; lobes 

 elongate, 7 — 15 c.M. long, 1 — S'/j c.M. broad, narrowed gradually towards 

 the acute or acuminate point, the margin subentire or slightly crenate to 

 repand; lowest lobes sometimes forked, slightly decurrent on the stipe. 

 Texture thinly coriaceous; surfaces naked, the lower pale-green; main veins 

 distinct, straight, parallel ; areolae with free veinlets. Sori round, large, super-
