Description
A description of Rhynchospora grayi is provided in The Flora of North America.
Distribution
Ecology
R. grayi was a species identified as indicating a recovered condition and perhaps high quality groundcover.[1]
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 (Archer et al. 2007).[2] It can also be found in sands of powerline corridors, and sandy fallow fields. 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. [2]
Soil types include dry sand, wet peaty soil, coarse sand, Humaqueptic Psammaquents, and sandy xeric soils. [2]
Phenology
Flowers and fruits April through July. [2]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by being consumed by vertebrates (being assumed). [3]
Conservation and management
Cultivation and restoration
