The wing uniting tlie higher, undivided or slightly incised pinnae 

 or pinnulae is broadest medial between the pinnae or pinrmlae, 

 becoming gradually narrower towards the place of union with the pinnae 

 or pinnulae. 



The texture, when seen towards the light (under the lens), is provided 

 with very numerous roundish, oblong or linear, simple or branched, free 

 or confluent groups of darker-coloured cells resembling spurious veins 

 subparallel with the real veins. The sori are placed on laterally compressed 

 increasing of the veins.
