edge and the outer half of the lower edge biserrulate or faintly inciso- 
crenate. Veins not close, excurrent, pinnately arranged, nearly all forked, 
but only one or two nearest the base repeatedly so. Sori on the anterior 
fork-branches, distant from each other, at angles of 20—60° with the 
midrib and at some distance from it and the margin, 10—13 on the upper 
half Sigua e near the base) and 6—9 on the lower. — Hook. & Grey
