This southeastern species of dry sandy soils is virtually unknown north of se Mo., se Ky. and se Va. (K). Colls. were made from Ky. during the 1930s (B) and the 1980s (J. Campbell at KY) from the same general locality in MCRE (Yahoo Ridge); see also Braun #4192 (US) from "south of Stearns" in MCRE. B's record from ROWA (Lockegee Rock) is based on a misidentified coll. of typical retrofractus (her cataloged coll. #4840 at US)
