Sori non-indusiate, large, rotundate, or by confluence elon- 

 gated, sometimes immersed; the receptacle produced on the 

 points where several reticulated veins join, i.e., compital. Veins 

 pinnate prominent, from a central costa ; venules compoundly 

 anastomosing in two or three series of irregular quadrate areoles, 

 within the ultimate of which are produced free divaricate sterile 

 veinlets. 



Fronds pinnatifid or pinnate, dimorphous, the sterile short
