This northeastern biennial (or short-lived perennial) of base-rich wet grasslands and shores is known close to Kentucky in Ohio and Tenn. as well as in parts of other adjacent states. However, it is endangered or locally extinct across the southern half of it range. It has not been found in Ky. for at least 50 years. The confirmed coll. of C.W. Short (KY) was from "wet barrens of Ky." and probably came from the vicinity of Hopkinsville in CHRI (M). A coll. of Pr from WARR or EDMO has not been located (check MO). A coll. from ROWA (MDKY) may have dubious label data (Campbell et al. 1992).
