 transverse anastomosing veins. Involucre involute, vaulted. — Frond pinnate or bipinnatifid ; 

 the fertile often contracted, serrulate or spinulose on the margin : veins reticulated ; the

 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 pinnae 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.
