Interpretive Summary: Recent research on plants from the southeastern United States has led the authors to recognize that several need different scientific names from the ones currently used. The reasons for the name changes are discussed, with details provided for each of the affected groups. The plants include a pipewort, a fleabane, goldenasters, goldenrods, a Spanish moss relative, sedges, blue-flowered wild indigo, a mountain mint, a sage, a skullcap, an orchid, and several grasses. It is essential to have agreed upon scientific names, that follow recognized naming conventions, for plants to communicate effectively about them.

Technical Abstract: As part of ongoing efforts to understand and document the flora of the southeastern United States, a number of taxonomic changes at generic, specific, and infraspecific rank are made. We also discuss and clarify the recommended taxonomy for other taxa (not requiring nomenclatural acts) and present a point of view about the practical and philosophic basis for making taxonomic changes in an allegedly well-understood flora. The genera (and families) affected are Endodeca (Aristolochiaceae), Erigeron, Pityopsis, and Solidago (Asteraceae), Tillandsia (Bromeliaceae), Carex (Cyperaceae), Baptisia (Fabaceae), Pycnanthemum, Salvia, and Scutellaria (Lamiaceae), Stenanthium (Melanthiaceae), Epidendrum (Orchidaceae), and Andropogon, Coleataenia, Dichanthelium, Digitaria, and Panicum (Poaceae).
