ABSTRACT A floristic survey was conducted of Crowders Mountain State Park for all vascular species from 2010–15. Crowders Mountain State Park was established in 1974 to protect a geologically unique North Carolina Piedmont site. In addition, it is known for its rare plant species. A total of 420 taxa was collected in this study, representing 418 species in 280 genera from 103 families. This includes 267 previously undocumented species for the park. Nine species are listed as either endangered, rare, of special concern, threatened, or watch-listed for North Carolina.
