| Description | The genera Mohria and Anemia (Anemiaceae: Pteridophyta) can be separated on both their sporangia and spores. In Mohria the capsule is globose with an apical annulus but in Anemia it is ovate-globose to cylindrical with a subapical annulus. The spores of both genera are radially symmetrical, tetrahedral and trilete with near parallel muri. The exinal sculpture in Mohria is cicatricose and in Anemia it can be canaliculate or cicatricose. In both genera the mural sets anastomose to form common muri that extend from near the distal pole to the equatorial radial region. The muri in Mohria are hollow and differ from those in Anemia which are solid or microporate. Supramural sculpturing in Mohria and Anemia is perinous. Spores of the other schizaealean ferns show no or little taxonomic affinities with Mohria and Anemia. In Actinostachys and Schizaea the spores are monolete and in Lygodium trilete but the exinal sculpture is smooth. | |
