 15 c.M. broad, + 9 c.M. high, covered with several conical or semiglobose 

 protuberances and subulate, simple or branched, scaly prickles (probably redu-

 lanceolate, acute, with the margin lobed with soriferous projections, the lobes 

 (projections) + oblong, oblique, rather distant, obtuse, narrowed at the base, 

 turned back on the upper surface of the frond, with the deeply immersed 

 sori facing upwards. Texture coriaceous; surfaces naked; veins indistinct. 

 Sori rather large, 5 — 6 m.M. long, + oblong, immersed in cavities of the 

 same shape, solitary on and occupying nearly Ihe whole of the lobe-like pro-
