Discussion

Bradburia pilosa grows in the western coastal plain province, southwestern central lowlands province, lower elevations of the Ozark Plateau province, and has possibly been introduced at a few locations in the interior low plateau province. It has possibly been introduced at a few sites in Kentucky, North Carolina, Virginia, and in Leon County, Florida.
