more than Vs mm. broad, passing gradually into the stipe, nearly 

 semiterete, the under surface rather flat, the upper surface convex, 

 sulcate in the lower half, the apes blunt. Texture coriaceous; surfaces 

 naked ; costa slightly prominent beneath, decurrent upon the stipe ; veins 

 invisible. Fertile fronds oblong or linear-oblong, decurved, naked, semi- 

 terete, 3 — 10 mm. long, + 2 mm. broad, + 1 mm. thick, the base 

 cuneate, the sides parallel, the apex narrowed, the point bluntish, the 

 under surface rather flat, the upper surface convex, grooved in the lower 

 half, the costa somewhat prominent beneath, decurrent upon the stipe. 

 Sori oblong, 1 — 6 on each side of and parallel to the costa, medial, 

 alternate, deeply immersed, at length prominent and confluent, occupying 

 the whole under side of the frond except the narrowed base and the 

 apex; sporangia sparingly setulose. — Very remarkable by its fertile 

 fronds resembling the long-stalked sporocarps of a moss.

 Fronds + 20 cm. long, 8— 9 mm. broad, obtuse, entire, narrowed gradually 

 towards the base. Texture rigidly coriaceous; surfaces nearly glabrous. 

 Sori in 1 row on each side of the costa, occupying the upper half of the

Rhizome creeping, scaly; scales squarrose, crowded, triangular-oblong,

 occupying the upper part of the frond, placed on the lowest anterior 

 veinlets, slightly immersed.
