Description
Distribution
Ecology
Habitat
In the Coastal Plain region, R. reniformis can be found in burned longleaf pine-wiregrass stands, burned upland longleaf pine forests, loamy sands of longleaf pine-oak scrubs, sandhills, savannas, sandy open areas, sandpine flatwoods, pineflatwoods on limerock, recently burned scrubs of cutover pinewoods, and turkey oak sand ridges (FSU Herbarium, Nelson 2005). 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).
Soil types include dry sand, sandy loam, loamy sand, limerock and gravelly sand (FSU Herbarium).
Phenology
It inconsistently flowers 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). 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).
