Abstract
A family of four very distinct, widely distributed genera, primarily of tropical or subtropical areas, except for Mohria, which is limited to southern Africa and adjacent islands. The spores are mostly large and trilete except for the monolete ones of Schizaea. The two-layered, blechnoid exospore forms the largest part of the sporoderm and usually the surface contours. A perispore of one to three layers usually conforms to the exospore but may form a more complex, silica bearing wall in some species of Lygodium. Fossil spores similar to or more elaborate than those of the extant genera are well known especially in Cretaceous deposits, and indicate the family was formerly more abundant and widely distributed.
