Sori indusiate, transverse marginal, sub-orbicular, distinct ; 

 the receptacles punctiform at the apex of the veius, generally 

 occupying the axils of the lobes. Indusium sub-orbicular, more 

 or less membranaceous, oblique. Veins simple or forked from a 

 central costa ; venules free. 



Fronds generally large, herbaceous, bi-tri-quadri-pinnate. 

 Ehizome extensively creeping. Somewhat wanting in technical 

 differences from both Cheilanthes and Adiantopsis, yet obviously 

 unlike either, and marked by the long creeping rhizomes, and 

 generally by the axillary position of the sori in reference to the 

 segments of the pinnules.

Sori indusiate, transverse, slightly intramarginal, sub-orbicular 

 or elliptic ; generally combined in pairs on the emarginate lobes, 

 single when the lobes or crenatures are entire ; the receptacles of 

 each sorus seated " on the termination of two veinlets," (Sk.) : 

 punctiform distinct, (ex Icon. Fee) : combining the venules, 

 fex Icon. Metten.) Indusium of the same form as the sorus, 

 membranaceous, inserted within the reflexed margin of the 

 soriferous lobes. Veins internal, quite obscure, forked ; in 

 the less divided species proceeding from a central costa; 

 venules free. 



Fronds coriaceous, tripartite pinnate or bi-pinnate. Stipes 

 and rachis ebeneous. Rhizome short, horizontal. A well- 

 marked genus, essentially distinguished by the somewhat intra-
