Discussion
Variety hispida occurs in the mountains and hills of western Maryland and Virginia, eastern West Virginia, and Surry County, North Carolina, where var. americana and Heuchera pubescens overlap; it is intermediate between var. americana and H. pubescens in floral characters. Variety hispida was confused with H. richardsonii for almost a century, beginning in 1849 when Gray reduced H. richardsonii to synonymy under H. hispida, after some seeds of H. richardsonii germinated among H. hispida plants in a labeled plot and later replaced them (C. O. Rosendahl et al. 1933).
