Sporangia in a single sorus or in several sori elongate along the lateral veins in a groove opening towards the costa, protected by 2 equal or unequal narrow industial flaps of tissue the same textrue as the lamina, one produced on the costa, the other on or beyond the soriferous veins, sporangia on 3-seriate, apically widened stalks; paraphyses filiform, annulus longitudinal, interrupted, of 14 -16 thickened cells.
