Discussion

Distribution for variety ravaudii is based on that given by H. Ando (1973), but it is doubtless infrequently scattered through the range of the species, producing sporophytes in summer. The variety is troublesome to determine because of its lack of the characteristic revolute leaf margins (except sometimes near the base), and the costa is difficult to discern.
