Rhynchospora compressa Carey ex Chapman. Pagoda Beaksedge. Phen: Apr-Aug (-Oct). Hab: Pine savannas. Dist: Se. NC south to Panhandle FL, west to e. LA. This species was reported for SC (Kartesz 1999), based on the South Carolina Plant Atlas (http://cricket.biol.sc.edu/herb/); McMillan (pers. comm.) states that the record is in error, based on a misidentified specimen. The species occurs in sc. GA (Jones & Coile 1988) and has since been found in SC by McMillan (2003) and in NC (Ungberg 2022).

ID notes:While superficially resembling a number of beaksedges, R. compressa has unique achenes that have flattened faces, faces with many strong transverse ridges, and a beak that recalls the roof of an oriental pagoda (triangular, with slightly upturned margin).

Origin/Endemic status: Endemic
