 stipe, which is somewhat chaffy. Sterile frond deeply pinnatifid ; the segments 8 - 12 on 

 each side, alternate, about 3 inches long and three-fourths of an inch wide, of a thin and 

 membranaceous texture, distinctly and sharply serrulate ; the veins much reticulated. Fertile 

 frond with the pinnas 2-4 lines wide, remotely and obscurely denticulate ; the margin often 

 revolute : veins few and slightly reticulated. Sori 3-4 lines long, prominent, in pairs which 

 are parallel with and near the midrib. Involucre with the free edge folded inward upon itself.
