Taxonomic notes
Description
Is strongly paraheliotropic.[1]
Distribution
R. tomentosa was found in the study area “within the Upper Coastal Plain Ecoregion with nearly level to gently rolling topography and a maximum elevation of 240m.” (Archer et al 2007).
Ecology
Habitat
In the Coastal Plains, R. tomentosa can be found in longleaf pine sandhills, pine-oak woodlands, slopes of old growth longleaf pine stands, wiregrass-longleaf pine woodlands, frequently burned mature longleaf pine-wiregrass stands, shady oak-hickory woods, longleaf pine turkey oak hills, hammocks, pine flatwoods, mature longleaf pine savanna, calcareous glades, and upland pine-oak woods (FSU Herbarium, Nelson 2005). It can also occur in recently burned scrubs of cutover pinewoods, former pine plantations, pastures, cut-over cedar glades, roadsides, near pond drains, old fields, powerline clearings, chalk prairies, and clearing of shortleaf pine stand. Associated species include Pinus palustris, Aristida stricta, Magnolia, Quercus, Rhynchosia reniformis and R. difformis (FSU Herbarium).
Soil types include sand, moist loamy soils, sandy loam, and loamy sand (FSU Herbarium).
Phenology
It blooms from May to June (Nelson 2005).
Seed dispersal
Seed bank and germination
Fire ecology
It was observed as an understory plant from frequently burned old-growth mountain longleaf pine stands at Fort McClellan, Alabama (Varner et al 2003).
Pollination
Use by animals
Diseases and parasites
Conservation and Management
Cultivation and restoration
R. tomentosa was found to be an indicator species in areas 30-80 years after clear-cutting in a southeastern mixed pine forest (Archer et al. 2007).
