Rhizome creeping, the scales short, ovate-lanceolate, short-acuminate. Sti- 

 pes 1 — 7 c.M. long, firm, often dark-coloured like the costa. Fronds 15 — 45 

 c.M. long, 1 — 3 c.M. broad, linear-lanceolate, the lower part narrowed very 

 gradually, the edge entire, or slightly and irregularly undulate, the upper part 

 more or less suddenly narrowed into a linear, contracted apex 1 — 15 c.M. 

 long, 2 — 4 m.M. broad, with the unaltered edge much recurved, quite enclos- 

 ing the sori when young. Texture rigid, chartaceous; surfaces naked; costa
