Gray (1884) included Ky. in the range of this northeastern shrub, but other editions of his manuals did not, neither has any other author. There is only one apparent wild coll. labelled as from Ky. It was made by C. Mohr in Sep 1883 from Bowling Green [WARR]; this coll. is located now at US but Gray may have been informed by Mohr. It is possible that plants occurred in rocky woods along the Green Rv. or in larger sinkholes. The species is known from within about 30-50 miles of the state line in Ind., Ohio, W.Va., Va., e. and c. Tenn. (K).
