Discussion
The geographic range of Heuchera caroliniana is contiguous with and appears to be a southern extension of that of H. pubescens. Heuchera americana var. americana occurs in counties adjacent to the range of H. caroliniana but they are sympatric only along the boundary; intergradation between the two is infrequent. Mixed populations of H. caroliniana and H. americana var. americana have not been seen.
