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. [1] Has been observed to grow on loamy sand soils. [1] 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.[2] Associated species include Pinus palustris, Quercus laevis, Q. incana, Q. stellata, and Aristida stricta. [1] Is also seen in human disturbed areas such as clearing of pinewoods and disked areas. [1]

Phenology

O. lupinellus is a perennial herb [2] and has been documented to flower and fruit May through August. [1]

Seed dispersal

This species is thought to be dispersed by gravity.[3]

Fire ecology

Has been observed to grow in recently burned longleaf pine forest. [1]
