Cedar Key Scrub State Reserve is located along the Gulf coast of Florida just north of Cedar Key and encompasses 2,020 ha (4,988 acres). Along with scrub, which is situated along ancient sand dune ridges, several other plant communities are distinguished; these are flatwoods, marshes, hardwood swamps, cypress domes, salt marshes, and ruderal habitats. Collections of vascular plants and bryophytes were made from March 1990 to December 1992. A total of 449 vascular plant species was collected representing 103 families and 274 genera. There were also 55 bryophytes, 26 mosses, 28 liverworts, and 1 hornwort.
