Sori indusiate, short oblong-lunate, or unequally or sometimes 

 equally hippocrepiform ; the receptacles on the anterior or some- 

 times also crossing and returning along the posterior side of the 

 veins, Indusium of the same form, often lacerate- fimbriate. 

 Veins simple or forked from a central costa ; venules free, some- 

 times pinnate. 



Fronds herbaceous, bi-tri-pinnate. Sori more or less generally, 

 the basal ones usually, rarely nearly all, arcuate. Rhizome short, 

 erect or creeping. — Neither the short sori, nor the fringed indusia 

 of this genus, though sometimes relied on, are sufficient to dis- 

 tinguish it from Asplemmnj the latter being too trivial, and the 

 former too variable and indefinite a feature, unaccompanied 

 moreover by any fixed habit. But the occurrence of hippo- 

 crepiform sori, more or less numerous, is abundantly distinc- 

 tive, and indicates a tendency towards the structure oi JOastrea. 

 The curved sori sometimes only just cross the vein at one end, 

 but are often continued some distance down the opposite side.
