Sort involucrately-indusiate, globose, marginal; the small 

 punctiform receptacles and pateriform i.e. shallow cup-shaped 

 membranaceous indusia, exserted and stipitate, terminating the 

 veins, which are excurrent in the marginal teeth ; the indusiu/m 

 extrorse-marginal, not recurved. Veins (of segments) simple, 

 rarely forked, from a central costa, free, reaching the margin, 

 beyond which those of the fertile teeth are exserted forming 

 stalks to the sori. 



Fronds herbaceous, pinnato-pinnatifid, proliferous. Ehizome 

 thick, decumbent. The peculiarity of this genus consists in its 

 cup-shaped indusia, standing out direct from the edge of the 

 frond on little stalks, which are variable in length. Sometimes, 

 it appears, the plants bear here and there athyrioid sori, as well 

 as the more abundant deparioid ones ; this probably occurs when 

 the plants are in a less vigorous condition, as we observe, that 

 in cultivation, the earlier fronds have the sori mostly sessile, 

 while afterwards, as the plants acquire vigour of growth, the 

 little footstalks of the sori are more developed.
