Description
Distribution
Ecology
In a burning x no shade treatment, R. reniformis was found to have elevated levels of N2-fixation (Hiers and Mitchell 2007). Herbivory damage for R. reniformis does not increase with time since fire (Knight and Holt 2005).
Habitat
It is found in sandhills, savannas, dry woods, and roadsides (Nelson 2005). In the Coastal Plain region, R. reniformis can be found in burned longleaf pine-wiregrass stands, sandy open areas, loamy sands of longleaf pine-oak scrub open woodlands, sandpine flatwoods, recently burned scrubs of cutover pinewoods, burned upland lonleaf pine forest, pineflatwoods on limerock, and turkey oak sand ridges (FSU Herbarium). It can also be found in open powerlines, clobbered slash pine forests, fallow longleaf pine-scrub oaks, and railroad embankments. Associated species include Galactia mollis, Desmodium floridanum, Desmodium strictum, R. tomentosa, Pinus palustris, Aristida stricta, slash pine, sand pine, Lactuca floridana, Serenoa repens, turkey oak, Acanthospermum, Polygala and Onosmodium (FSU Herbarium).
Phenology
It is inconsistently from April to September (Nelson 2005).
Seed dispersal
Seed bank and germination
Fire ecology
R. reniformis is a legume found in frequently burned longleaf pine savannas (Brewer and Cralle 2003, Hiers and Mitchell 2007). It was observed to resprout one month after a fire in July of 1993 (Pavon 1995).
Pollination
Use by animals
Diseases and parasites
