Taxonomic notes


A description of Rhynchospora harveyi is provided in The Flora of North America.




In the Coastal Plain in Florida and Georgia, R. harveyi can be found in longleaf pine forests, drying sandy loam of open pine-oak woodlands, and on dry wiregrass/longleaf pine sandhills.[1] It can also occur in cutover pinewoods with Fimbristylis and Cyperus, sandy loam on pond margins, roadsides, and partially cutover upland longleaf pine savannas.

R. harveyi became absent in response to soil disturbance by agriculture in southwest Georgia savannas. It has shown resistance to regrowth in reestablished savanna habitat that was disturbed by agricultural practices.[2]

Associated species include Pinus palustris, Aristida stricta, Quercus, and Fimbristylis, Cyperus.[1]


This species has be observed to flower in August[3] and fruits May through September.[1]

Seed dispersal

This species is thought to be dispersed by gravity.[4]

Fire ecology

Populations of Rhynchospora harveyi have been known to persist through repeated annual burns.[5][6]

Conservation, cultivation, and restoration

R. harveyi should avoid soil disturbance by agriculture to conserve its presence in pine communities.[2]
