This is a widespread, variable northern tree that is known close to Ky. in se. Ind., se. Ohio and perhaps W.Va. (K). There are some old obscure reports from Ky. (M), plus more recent reports from northeastern counties, but none are verified (Little 1971, Campbell et al. 1992). There has been some confusion with grandidentata. An apparently spontaneous hybrid of tremuloides and grandidentata occurs at the Boone County Arboretum (K. Stone, pers. comm.). Hybrids can also be expected with the Eurasian species, P. alba and P. tremula L. (FNA 7).
