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.

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

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 roembrana' 

 ceous ; veins anastomosing irregularly ; i areolae 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.
