Rhynchospora macra (C.B. Clarke) Small. Southern White Beaksedge. Phen: Jul-Sep. Hab: Sphagnum bogs in frequently-burned streamhead pocosins, and in sandhill seepage bogs. Dist: Sc. NC south to ne. FL, FL Panhandle, and west to se. TX; Nicaragua; Puerto Rico.

Origin/Endemic status: Native

Other Comments: R. macra is a robust southern relative of R. alba. Like R. alba and R. pallida, it has scales which are at first bright white, "fading" in age to a medium tan or light brown. These three species are thus superficially most distinctive (from other Rhynchospora) in June, July, and August. The occurrence of this species in NC and SC is discussed by Sorrie et al. (1997).
