Abstract
Over the past 14 years, an effort was made to summarize and improve our knowledge of the Arkansas pteridophyte flora beyond that developed by Taylor and Demaree (1979). They presented a flora of 68 species plus 2 varieties plus 4 hybrids, for a total of 74 taxa vouchered with 1335 county-level occurrence records. Changes in accepted nomenclature, field work, and herbaria searches have added as new to the flora 10 species plus 1 variety plus 7 hybrids, supported with 74 county-level occurrence records. Another 815 county-level occurrence records were added to the known flora. The Arkansas pteridophyte flora now consists of 78 species plus 3 varieties plus 11hybrids, supported with 2224 county-level occurrence records. Achecklist, 92 distribution maps, a history of Arkansas pteridophyte floristics, corrective nomenclatural notes, and a phylogeny based ona recent national treatment on pteridophytes are provided.
