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

 the receptacles punctiform at the apex of the Teins, 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, 



Bhizome extensively creeping.— Somewhat wanting in technical 



differences from both CheilantAes and Adianfopsis, 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," (Mk.J : 

 punctiform distinct, fex Icon. Fee) : combining the venules, 

 ('ex Icon. Metten.J 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; 

 vemiles free. 



JVonds coriaceous, tripartite pinnate or bi-pinnate. Stipes 

 and raohis ebeneous. Ehizome short, horizontal. — A well- 

 marked genus, essentially distinguished by the somewhat intra-
