Description
Distribution
Ecology
Habitat
Habitats of O. lupinellus are sandhills, sandy pine-oak woods, scrub oak ridges, longleaf pine forests, slopes and upland oak-pine woods (FSU Herbarium). Has been observed to grow on loamy sand soils (FSU Herbarium). In a study comparing N2 fixation potential in nine legume species occurring in longleaf pine-wiregrass ecosystems, O. lupinellus had the lowest potential for N2 fixation (Cathey et al. 2010). Associated species include Pinus palustris, Quercus laevis, Q. incana, Q. stellata, and Aristida stricta (FSU Herbarium). Is also seen in human disturbed areas such as clearing of pinewoods and disked areas (FSU Herbarium).
Phenology
O. lupinellus is a perennial herb (Cathey et. al 2010) and has been documented to flower and fruit May through August (FSU Herbarium).
Fire ecology
Has been observed to grow in recently burned longleaf pine forest (FSU Herbarium).
