Abstract

Two hybrid wood ferns (Dryopteris X bootii {Tuckerm.} Underw. and Dryopteris X uliginosa {A. Br.} Deuce) are reported as new to Iowa. An additional 118 county records for 30 species and hybrids are summarized. Observations on possibly extirpated Iowa pteridophytes and on the status of extant populations of the rarest Iowa pteridophytes are reported, including the rediscovery of lsoetes melanopoda, not observed in Iowa since its original discovery in 1863. The Iowa pteridophyte flora, the subject of a decade of field and herbarium study, consists of 57 species and 7 hybrids, supported with 1450 county collections.
