Description
R. corniculata is a perennial graminoid of the Cyperaceae family native to North America.[2]
Distribution
R. corniculata is found in the southeastern corner of the United States.[2]
Ecology
Habitat
R. corniculata proliferates in pondcypress savannas in Carolina bays, swamp forests, and other wetlands.[1] Specimens have been collected from moist loam, shaded mucky soil, floodplain swamp, shaded river bank, bottomland woods, marshy creekbed, edge of water in dense pine canopy, and upper tidal swamp of mixed forest.[3]
Rhynchospora corniculata is an indicator species for the Panhandle Seepage Savannas community type as described in Carr et al. (2010).[4]
Phenology
R. corniculata has been observed flowering in July and September.[5]
Fire ecology
R. corniculata is not fire resistant, but has a medium fire tolerance.[2] Populations have been known to persist through repeated annual burning.[6]
Conservation, cultivation, and restoration
R. corniculata is listed as threatened by the Indiana Department of Natural Resources Division of Nature Preserves, and as a weedy or invasive species by the Southern Weed Science Society.[2]
