Rhynchospora solitaria R.M. Harper. Common name: Autumn Beaksedge. Habitat: Wet, sandy/peaty depressions. Distribution: Known from a few sites in the Gulf Coastal Plain of GA (Colquitt, Irwin, Tift, and Turner counties) (Sorrie 1998b) and SC (Berkeley County) (McMillan & Porcher 2005). It should be sought in seepage bogs in the Fall-line Sandhills of the Carolinas and in wet pine savannas of the outer Coastal Plain.

ID notes: Rhynchospora solitaria resembles a delicate R. ciliaris; its distinctiveness is well described in Bridges & Orzell (1992).

Other Comments: This is the rarest species of Rhynchospora in the southeastern United States. Live plants (outside of the only known cultivated plants at SC Botanical Gardens) have not been seen since 2004.
