A survey of the vascular flora of Dale County, AL, was conducted from August 1999 through December 2000. Dale County consists of 145,039 ha in the southeastern section of Alabama and occurs entirely within the Coastal Plain Province. Plants were collected from all major habitats within the county, including xeric and mesic woods, fields, floodplains, and swamps. Additionally, a search of the pertineant literature was conducted, and the herbaria at Troy University (TROY), Auburn University (AUA), and The University of Alabama (UNA) were searched for taxa not collected during this study. A total of 921 species, representing 458 genera and 142 families, were found within the county. The largest families were Asteraceae (121 species), Poaceae (94 species), and Fabaceae (75 species). Twenty-one of the taxa documented for this study are globally or state ranked for rarity of occurrence.
