Description
A description of Rhynchospora grayi is provided in The Flora of North America.
Distribution
Rhynchospora grayi is widespread throughout the southeastern Coastal Plain with disjunct populations in western Cuba.[1]
Ecology
R. grayi was a species identified as indicating a recovered condition and perhaps high quality groundcover.[2]
Habitat
In the Coastal Plain in Florida and Georgia, R. grayi can be found in longleaf pine forests, longleaf pine-wiregrass ridges, pine-oak forests, burned pine flatwoods, dry pine barrens, recently burned wiregrass/pinewoods, peaty depressions in flatwoods, sandy lake shores, turkey oak-slash pine woodlands, and sandy xeric bluffs bordering creeks.[2][3] It can also be found in sands of powerline corridors, and sandy fallow fields.[3]
Associated species include Pinus palustris, Aristida stricta, Quercus laevis, Q. geminata, Q. margaretta, Q. incana, Licania, Stillingia sylvatica, Tragia smallii, T. urens, Rhynchosia reniformis, Croton argyranthemus and sand pine.[3]
Soil types include dry sand, wet peaty soil, coarse sand, Humaqueptic Psammaquents, and sandy xeric soils.[3]
Rhynchospora grayi is frequent and abundant in the Peninsula Xeric Sandhills and Panhandle Xeric Sandhills community types as described in Carr et al. (2010).[4]
Phenology
R. grayi has been observed flowering from April through July and in October, and fruiting April through July.[3][5]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates.[6]
Fire ecology
Populations of Rhynchospora grayi have been known to persist through repeated annual burning.[7]
