Trunk 1 — 2 M. high, slender. Stipes unarmed, angular, rufo-stramineous, 

 + 10 c.M. long, densely clothed with narrow, subulate, aristate scales provid- 

 ed with a black-brown central line. Fronds 2-pinnate, + 65 c.M. long, 

 ± 25 c.M. broad, ovate, acuminate, narrowed towards the base; rachises 

 scaly like the stipe, but the scales adpressed, shorter and the main rachis 

 clothed on the upper side with short, grey pubesence. Pinnae close, ± 

 15 on each side, broadly oblong; central pinnae largest, ± 15 c.M. long, 

 ± 6 c.M. broad, sessile, acuminate. Pinnulae ± 16 on each side, lanceolate, 

 close, sessile, + ^'/j c.M. long, + 1 c.M. broad, cut to '/g-way down (or 

 rarely nearly) to the costa. Lobes triangular, acute, + 6 on each side, obtuse, 

 entire, ± 3 m.M. each way, the lowest posterior one adnate, the lowest ante- 

 rior overlapping the rachis. Texture coriaceous; surfaces naked, upper 

 black-green, lower paler; main veins pinnate in the lobes; veins ± 3 on 

 a side, distinct, simple. Sori 2—3 to a lobe; indusium persistent, co- 

 riaceous, brown, at length breaking up into irregular pieces. — This
