base narrowed gradually into the stipe, the edge narrowly revolute. Texture 

 rigidly coriaceous; surfaces naked; colour yellow-greenish; costa prominent, 

 stramineous: veins hidden. Sori oblong, rather large, submarginal, impressed, 

 with a space less than their own length between them, the higher ones 

 protruded beyond the margin.

Rhizome wide-creeping, very strong, the scales short, furfuraceous. Fronds 

 subsessile, usually in distant pairs, uniform, entire, + 7^2 — IS c.M. long, 

 1 — S'/j c.M. broad, narrowed towards both ends, the point often blunt. 

 Texture coriaceous; surfaces naked; areolae copious, small, with numerous

 long. Fronds simple, lanceolate-oblong, + 15 c.M. long, 2^2 — 4 c-M. broad,

Rhizome creeping, slender, clothed with scattered, brown, membranaceous, 

 lanceolate, acuminate scales. Fronds sessile, remote, imbricating, simple. 

 Barren fronds suborbicular, entire, cordate at the base. Texture membrana- 

 ceous; veins anastomosing irregularly; arreolae large, enclosing smaller ones 

 with few free veinlets ; costa disappearing + towards the centre of the frond. 

 Fertile fronds similar but the apex suddenly produced into a long, narrow, 

 linear-lanceolate fertile part several times longer but much narrower than the 

 barren part, with the costa distinct quite to the point. Sori ± oblong, in 

 1 — 2 rows on each side of the costa.
