The fronds are exactly like those of Microlepia Wtlfordii MOORE or M. rhom- 

 boidca (HooK. 2nd Cent. Fern. t. 48), but the fructification is undoubtedly that of 

 Dryopteris. Indusium is generally cordate or sometimes oblong, attaching to the 

 fronds by one side and tends to be like that of Atliyrium. It is especially so towards 

 the apex of the fronds. 

 Near Cystopteris Doii- 

 c/lasn (HooK. Ic. PI. t. 

 955) and Cystoptcrix 

 tasmanica (HooK. Ic. PI. 

 t. 955), but differs from 

 them by the petiolate 

 more deeply lobed or 

 pinnatifid pinnae.
