Description
O. lupinellus is a perennial herb, native to southern North America and Mexico. Its corolla is blue, pink, or violet and the leaves are palmately 5-7 foliate. The leaflets are linear to narrowly oblanceolate. They're 2-7 cm long and 0.5-2.0 (-3.5) mm wide; normally over 10x long as wide.[1]
Distribution
This species is endemic to the southeastern Coastal Plain, ranging from southcentral and southeastern North Carolina to central peninsular Florida, southern Alabama, and eastern Georgia.[1]
Ecology
Habitat
Habitats of O. lupinellus are sandhills, sandy pine-oak woods, scrub oak ridges, longleaf pine forests, slopes and upland oak-pine woods.[2] It has been observed to grow on loamy sand soils.[2] 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.[3] Associated species include Pinus palustris, Quercus laevis, Q. incana, Q. stellata, and Aristida stricta.[2] Is also seen in human-disturbed areas such as clearing of pinewoods and disked areas.[2]
Phenology
O. lupinellus is a perennial herb[3] that flowers from May through July[4] and fruits from July through August.[1]
Seed dispersal
This species is thought to be dispersed by gravity.[5]
Fire ecology
O. lupinellus has been observed to grow in recently-burned longleaf pine forests.[2] Populations have been known to persist through repeated annual burning.[6]
