Rhizome creeping, densely clothed with subulate-lanceolate, fibrillose scales. 

 Stipes erect, strong, 10 — 30 c.M. long, scaly towards the base. Fronds 

 oblong, 15—40 c.M. long, 7—20 c.M. broad, simply pinnate with 8 — 20 

 short-stalked, erecto-patent pinnae on each side below the terminal one. 

 Pinnae linear, 4 — 20 c.M. long, 3 --10 m.M. broad, acuminate, the base cuneate, 

 the edge slightly crenate or toothed. Texture coriaceous; rachis and sur- 

 faces naked. Sori 1 — 2 to each tooth, more broad than long, sometimes 

 confluent.

Rhizome creeping, densely clothed with small, brown, subulate-lanceolate, 

 fibrillose scales. Stipes ± 5 — 10 m.M. apart, 10—15 c.M. long, densely 

 scaly at the base. Fronds oblong-lanceolate, 20 — ."^0 c.M long, to 17 c.M. 

 broad. Texture coriaceous; rachis and surfaces naked. Sori 1 — 2 to each 

 tooth, the pairs often ± confluent. — Two forms. 



Forma grandidentata : Fronds simply pinnate. Pinnae linear, + 5 — 15 

 m.M. broad, deeply toothed or subpinnatifid, the teeth or lobes broad, obli- 

 quely deltoid, reaching down nearly to the costa. 



Forma dissecta : Fronds pinnate. Pinnae + 2 — 5 c.M. broad, deeply 

 pinnatifid nearly to the costa or pinnate again, the segments linear or oblong, 

 entire or obliquely toothed, the base adnate, decurrent or cuneate. 



Both forms may be found on the same rhizome.
