There have been several reports from Ky. of this northeastern and high Appalachian species, but there have been misidentifications among this and related species (see notes under albus). Also, there may have been some hybridization with serpentarius and other species in different parts of its range (FNA 19). There is no verification of trifoliolatus in Ky. There is an immature coll. from HARL (MDKY) that may be this species. There is a verified coll. labelled as from ROWA (MDKY), but it is not accepted due to probable error in the data (Campbell et al. 1992). However, the species is known from nearby Scioto Co., Ohio, in hills similar to parts of ne. Ky. (PL; D. Boone, pers. comm.).
