Heuchera pubescens Pursh. Section: Heuchera. Subsection: Heuchera. Marbled Alumroot. Phen: May-Jul. Hab: Rocky forests, rock outcrops, particularly where soils are subacidic or circumneutral. Dist: Primarily a species of the Ridge and Valley Province of PA, MD, WV, and VA, H. pubescens ranges south to only a few locations in the upper Piedmont of NC. The report in RAB of the occurrence of H. pubescens in Madison County, NC, is apparently erroneous; Wells (1984) shows H. pubescens reaching its southern limit just south of the VA border, and not occurring at all in KY, TN, or the mountains of NC. She found the bract characters used in the key in RAB to be unreliable. Reported by Hill & Horn (1997) for South Carolina {report needs verification}.

Origin/Endemic status: Endemic

Other Comments: See discussion under H. alba.
