3 to 9 lines long, 8 to 4 lines broad near the base, where the upper half is truncate 

 and parallel with the rhachis, while the lower halt is obliquely cut away nearly to 

 the midrib ; the apex obtuse or on the upper segments or pinnsB nearly acute, 

 margins crenate. Costa very slender, veins distant, simple or forked, very 

 oblique'. Sori rather long, distant from the costa but approaching the margin.—
