To prior reports on the studies of the Iowa pteridophyre flora, five taxa (Botrychium campestre Wagner & Farrar, Botrychimn matricariifolium A. Braun, CyJtopterislragilis (L) Bernh., Cystopteris laurentiana (Weath.) Blasdell, and Lycopodium inundatum L.) are added, along with 215 new county occurrence records for 39 taxa. Currently, the Iowa preridophyte flora consists of 70 taxa, supported with 1656 county occurrence records; only 72 (4%) of these records are based solely on collections made before 1950.
