Rank Reasons
Lupinus villosus is a perennial herb that is endemic to the southeastern United States where it occurs from North Carolina south to Florida and west to Louisiana. It is common throughout most of its range, except Louisiana (westernmost edge) and North Carolina (northernmost edge) where it is rare. Fire suppression, development, and road maintenance are threats.
Range Extent Comments
Lupinus villosus is endemic to the southeastern United States where it occurs from North Carolina south to Florida and west to Louisiana (Weakley and Southeastern Flora Team 2022).
Occurrences Comments
It is common throughout most of its range, except Louisiana (westernmost edge) and North Carolina (northernmost edge) where it is rare (NatureServe 2022, Weakley and Southeastern Flora Team 2022). Based on NatureServe Network occurrence data, herbarium records, photo-based observations, and anecdotal evidence, there are likely over 300 occurrences rangewide (GBIF 2022, SEINet 2022, iNaturalist 2022, NatureServe 2022).
Threat Impact Comments
This species occurs in a fire maintained habitat, thus fire suppression is a threat. Some occurrences are on roadsides, where maintenance of vegetation may range from favorable to detrimental. Development is a threat, especially in southeastern Louisiana (C. Doffitt, pers. comm., 2022).
Ecology & Habitat

Habitat

This species occurs in well-drained sandy soils of longleaf pine sandhills and roadsides (Weakley and Southeastern Flora Team 2022). Road maintenance likely simulates the disturbance of fire that is necessary to maintain longleaf pine forests
