Description
L. virginica is a perennial forb/herb of the Fabaceae family native to North America and Canada.[1] It is an erect perennial that is 0.3-1 m tall. The stem is glabrate to moderately pubescent, mostly erect, can be ascending, and usually branched. Leavesare alternate, pinnately trifoliolate compound; leaflets 3, linear to narrowly oblong, without stipels. The leaflets are linear to narrowly oblong, 0.6-2.5 cm long, and 3-5 times long as wide. They are sparsely strigillose to glabrate above and densely strigillose beneath with narrowly linear stipules. Racemes are few-several flowered, axillary, and exceeded by leaves. Inflorescence peduncles and axes are densely strigillose with 0.5-1.2 mm long pedicels. Calyx is densely strigillose or puberulent with 1.2-2.4 mm long lobes. The petals are roseate to purplish and 5-7 mm long. l fruit is a 1-seeded, indehiscent pod. Legumes are broadly elliptic to ovate, 3-6 mm long, conspicuously reticulate, and sparsely strigillose.[4][5]
Distribution
L. virginica ranges from Massachusetts, and New Hampshire, west to Michigan, Wisconsin, and Iowa, the south to Panhandle Florida and Texas. It also grows in the Ontario region of Canada.[1][3]
Ecology
Habitat
L. virginica proliferates in sandhills, woodlands, and woodland borders.[2] Specimens have been collected from annually burned pineland, drying sandy loam of pine-oak woods, border of roadside and woodland, beech-magnolia forest, old field, old field with pine woods, open stand of shortleaf pine with snady clay, young slash pine plantation, disturbed regions such as roadsides and fields, and longleaf pine wiregrass ridge.[6]
L. virginica had variable changes in occurrence and abundance in response to clearcutting and chopping in South Carolina. It has shown either regrowth or been unaffected in reestablished habitats that were disturbed by clearcutting and chopping.[7]
Phenology
L. virginica flowers from July to September and fruits from August to November.[3]
Seed dispersal
This species is thought to be dispersed by gravity.[8]
Fire ecology
L. virginica increases in abundance with increasing fire frequency.[9] Populations have been known to persist through repeated annual burns.[10]
Conservation, cultivation, and restoration
L. virginica is listed as threatened by the New Hampshire Natural Heritage Inventory Division of Land and Forests and by the Wisconsin Department of Natural Resources Bureau of Endangered Resources.[1]
