 naked; veins indistinct. Sori on the lobules, round or oblong, deeply

 linear-oblong, l'/^— 2 cm. broad, entire, obtuse; fertile pinnae lanceolate, 

 to 1 cm. broad, deeply crenate (toothed?), the teeth retroflexed (turned 

 back on the upper surface of the pinnae.). Texture thin ; under surface
