This study is a compilation of vascular flora data from previous reports and current findings from 1965 through 2003 of Fort Bragg Military Reservation and Weymouth Woods Sandhills Nature Preserve, located in the Sandhills region of North Carolina. Vascular plants are divided into four major groups: Pteridophytes, Gymnosperms, Angiosperms (monocots) and Angiosperms (dicots). Reported for the study area are 143 families, 490 genera, and 1,206 species and infraspecific taxa, of which 203 (16.8%) are alien or adventive. Sixty one species are rare, of which three are federally endangered: Lysimachia asperulifolia, Rhus michauxii, and Schwalbea americana. The following five species are currently known in North Carolina only from study area populations: Carex tenax, Hypericum fasciculatum, Pteroglossaspis ecristata, Rhynchospora crinipes, and Warea cuneifolia. This study documents the importance of Fort Bragg Military Reservation and Weymouth Woods Preserve in contributing to the floristic diversity of the longleaf pine-wiregrass ecosystem.
