Sori indefinite, covering the whole under surface of the much contracted, 

 nearly linear fertile fronds. 



Rhizome creeping. Fronds scattered, not articulate to the rhizome, di- 

 morphous. Barren fronds simple or more generally 2-fid, the lobes sometimes 

 2-lid again; main ribs 2 or more in each lobe, uniting towards the apices 

 of the segments; veins anastomosing copiously. Diels, in Engl, k Prantl, Nat.
