This occurs mostly in pine savannas on the Coastal Plain, but has disjunct populations from the Ozarks to the Appalachians. In Ky. there are records from only a few sites, which are probably remnants of thin woods or grassy openings, especially on seasonally wet acid soils. Only one or two populations are currently known to exist. Some records reported by NP need verification: BARR, LINC (B. Yahn, pers. comm.), WARR.
