Abstract
The specimens assigned to the genus Dryopterites Berry were reexamined and details of the reproductive characters including the spores are described for the first time. Based upon this new information about the ferns, two species have remained in the genus Dryopterites with one designated as the type species (D. virginica) and a lectotype for this species is chosen: one species (D. dentata) has previously been reassigned to the family Schizaeaceae, and the remaining species (D. macrocarpa, D. elliptica, D. cystopteroides) have been assigned to the genus Delosorus in the family Matoniaceae. This new information and comparisons with Sporae Dispersae suggest a later Cretaceous occurrence of ferns related to the modern dryopterids.
