This midwestern species is similar to virginiana, but clearly differs in its glandular inflorescence. It is known from a few sites in s. Ill. and s. Ind. (K, PL), but there are only vague reports from Ky. It was listed for Ky. by BA (check MEM or EKY), and more tentatively by M from BULL (based on a coll. at Oklahoma State Univ.).
