Rhynchospora globularis (Chapman) Small. Globe Beaksedge. Phen: Jun-Sep. Hab: Sandy or peaty depressions, wet ditches, powerline corridors, pine savannas, inland in acidic seeps and flatwoods. Dist: DE south to s. FL and west to c. TX and OK; north in the interior to nc. TN; disjunct around the Great Lakes.

ID notes:Both R. globularis and R. pinetorum tend to produce shorter plants with smaller glomerules than R. recognita. Occasional achenes of R. globularis exhibit the wide alveoli of R. pinetorum near the base or summit, with little or no horizontal ridging, but centrally have narrow alveoli with pronounced horizontal ridges. The opposite condition occasionally occurs in R. pinetorum achenes, with narrow alveoli and horizontal ridging basally or at the summit, but wide alveoli and little or no ridging centrally.

Origin/Endemic status: Native
