segments 5 — 8 c.M. long and 6 — 7 m.M. broad at the middle, tapering

Stipes ± 40 c.M. long, red-brown, ± densely clothed with small, 

 ferrugineous hairs, + rough below, slightly canaliculate. Fronds ± 48 

 C.M. each way, deltoid-ovate, 2-pinnatifid. Terminal pinna deeply pinnatifid, 

 the lobes + falcate, entire, acuminate, the lowest lobe bluntly lobed; 

 below this 2 pairs of lateral pinnae, which are + falcate, acuminate, with 

 the lower side more or less deeply lobed, the lobes blunt or acumi- 

 nate, falcate, lowest pinnae on stalks ± 5 c.M. long. Texture papyraceous; 

 rachis, costae and main veins hairy like the stipe; main veins distinct 

 nearly or quite to the edge; areolae moderately large, with free veinlels.

 Fronds 15 — 45 c.M. long, 10 — 30 c.M. broad, subdeltoid, the apex deeply

 deeply pinnatifid pinnulae, the higher ones less divided. Texture papyraceo- 

 herbaceous; surfaces naked or somewhat puberulous; main veins distinct; 

 areolae rather large, with free veinlets. Sori large, in rows near the main
