Stipes tufted, castaneous, + 45 c.M. long, with only a few, small, brown, 

 lanceolate scales at the base. Fronds deltoid, 30—40 c.M. long, ralher less 

 broad, with a deeply pinnatilid, large terminal pinna with short, obtuse upper 

 lobes and large, lanceolate lower ones ; below this 2 — 4 lanceolate, free 

 pinnae, the lowest ones unequal-sided and forked at the base on the lower 

 side. Texture moderately firm; both surfaces naked; main veins distinct to 

 the edge, slender, erecto-patent, with very copious areolae between them, 

 with free veinlets. Sori very abundant, minute; indusiuni minute, very 

 fugacious.

Rhizome creeping. Stipes 30 c.M. long or longer, subsLramineous or 

 brownish. Fronds 30 — 90 c.M. long and 20 — 75 c.M. broad, rarely smaller, 

 subdeltoid, with a large, often deeply pinnatifid apex with entire or broadly 

 toothed, lanceolate lobes ; below this 1 — 2 pinnae on each side, the lowest 

 stalked, distant, forked at the base or pinnatifid, the apex lanceolate. Texture 

 herbaceous to semicoriaceous ; surfaces somewhat hairy beneath and on the 

 main veins above; main veins distinct to the edge; areolae fine, with copious 

 free veinlets. Sori often moderately large, confined to the united veins.

Rhizome erect, woody. Stipes 15 — 20 c.M. long, naked or nearly so, 

 winged, the wing + 5 m.M. broad on each side, narrowed gradually towards 

 the base. Fronds 20 — 50 c.M. long, 3 — 5-partite. Terminal (or central) seg- 

 ment oblanceolate, 4 — 5 c.M. broad, acuminate, irregularly serrate or toothed, 

 the teeth — 1 c.M. long, lateral segments smaller, erecto-patent, obscurely 

 serrate. Texture herbaceous; surfaces naked; main veins reaching the margin; 

 areolae irregular, with free veinlets. Sori large, in rows near the main veins; 

 indusium persistent
