Actaea rubifolia (Kearney) Kartesz. Section: Oligocarpae. Appalachian Black-cohosh. Phen: Aug-Oct. Hab: Rich cove forests over calcareous rocks (limestone or dolostone), westwards in shaded sandstone ravines. Dist: Sw. VA south to e. TN; disjunct in s. IL, w. KY, nw. TN, and nc. AL. This species is alleged by C (1991) to occur in NC, but this is probably an error, based on confusion with Cimicifuga cordifolia Pursh, now considered a form of Actaea racemosa. For this reason, the name Actaea cordifolia used by Compton, Culham, & Jury (1998) does not apply to this taxon.
