Darcea Sori oblong; veins mostly simple hi the (usually) unisoriferous

 both ends ; fronds 2- 3- pinnate.

Sori indusiate, short oblong-luuate, 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 Asplenium, 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 of Lastrea. 

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

 but are often continued some distance down the opposite side.
