Fructifications paniculate on the lower (pair of) branches of a 

 branched frond, the branches erect 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 costa ; 

 venules irregularly anastomosing in narrow oblique elongated 

 areoles. 



Fronds pinnate, the fertile always ternately branched, the two 

 lateral branches distinct erect fertile, the terminal one spreading 

 sterile. Ehizome 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,
