According to the Atlas of Florida Plants, the "species had been placed often in Gratiola, but recent work favors its segregation as part of a genus sister to the rest of Gratiola s.s. (Estes 2008; Estes & Small 2008)." Mostly endemic to Florida and southeast Georgia, it has also been identified in a few counties of Alabama and Louisiana.
