 auricle often free or truncate with a subtriangular auricle 

 sometimes the piiuia? are deeply pinnatifid in a regular man-

 the piimules various in shape entire or serrated, veins oblique 

 once or twice forked, sori oblong generally copious arranged 

 in two series between the costa and margin often confluent, 

 indusium rigid-membranaceous of the same colour as the
