apices slender caudate pinnatifid, ultimate pinnules rather 

 long-petiolulate from a cuneate base rhomboid-truncate or 

 acuminate variously incised or pinnatifid in the upper half 

 and dentate, veins pinnated not extending to the margin dis- 

 tant, sori linear in two oblique series or rows, in the broader 

 pinnules remote from the margin, in the narrow segments 

 dareoid, involucres pale brown, rachises slender almost fili-
