Fructijications paaiioulats on the lower (pair of) branches of a 

 branched frond, the branches erecfc contracted rachiform decom- 

 pound, the segments unilaterally sporangiferous. Spore-cases 

 oval, having a many-rayed apical ring, sessile, bi-serial on the 

 ultimate segments. Veins parallel-forked, from a central oosta ; 

 vewules irregularly anastomosing in narrow oblique elongated 

 areoles. 



Fronds pinnate, the fertile always temately branched, the two 

 lateral branches distinct erect fertile, the terminal one spreading 

 sterile. Rhizome short erect. — The reticulated venation distin- 

 guishes this genus from Anemia. Probably all the so-called 

 species should be considered as varieties of one species.

 pinnules. Spore-cases scattered or sub-solitary, sub-globose.
