25 — 30 c.M. broad, ovate-lanceolate, with a long, terminal, pinnatifid pinna. 

 Pinnae erecto-patent, alternate, ± 2^2 — 3 c.M. apart, linear-lanceolate, 15 — 20 

 c.M. long, 15 — .20 m.M. broad, the apex narrowed to an acute point, the 

 margin cut '/s — Vs'^^^Y down into subacute (rather bluntish), slightly falcate 

 lobes, obscurely crenate at the apex. Texture papyraceous ; rachis dark-reddish- 

 brown, slightly canaliculate and hairy and scaly on the upper side, the scales 

 large, pale-brown ; upper surface covered with pale or whitish hairs on the 

 costae and rarely on the costulae and veins; under surface finely glandular; 

 veins + 8 — 10 on each side, only the 3 lowest ones anastomosing. Sori 

 costular, confined to the 4 — 5 lowest veins; indusium very fugacious.

Rhizome strong, erect. Stipes densely tufted, a span or more long. 

 Fronds deltoid or somewhat lanceolate, 30 — 40 c.M. long, 15 — 18 c.M. broad. 

 Pinnae cut down ^/g or more towards the costa into entire, slightly falcate
