A floristic study of Iowa pteridophytes is presented based upon extensive herbarium and field work. Historical notes are included on the principal collectors, along with a summary of the accumulation of floristic records. Taxonomic notes are presented on seven taxa new to the state and on six excluded taxa. A flora of 57 species and 3 hybrids is recognized. Floristic notes are presented on the status of the state flora and county floras. The addition of 402 new county records increases the total of county occurrences by 47%. Statements of habitat and distribution are presented with dot maps for the entire flora. Records requiring new collections are identified, along with counties needing further field study and species that require special attention.
