This alliance accommodates rich fen vegetation of the Southern Blue Ridge and related areas of the Southern Appalachians, adjacent Central Appalachians, and Ridge and Valley provinces of the southeastern United States. Dominant species in herbaceous examples vary spatially with the amount of seepage and type of substrate, but typical dominants include <i>Carex buxbaumii, Carex stricta, Cladium mariscoides, Helenium autumnale, Juncus subcaudatus, Muhlenbergia glomerata, Parnassia grandifolia, Rhynchospora alba, Rhynchospora capitellata, Sanguisorba canadensis, Schizachyrium scoparium</i>, and <i>Solidago uliginosa</i>. In the Ridge and Valley of northeastern Tennessee, species present include <i>Cardamine bulbosa, Carex atlantica ssp. capillacea, Carex leptalea, Carex lurida, Carex scoparia, Carex stipata, Carex stricta, Carex virescens, Carex vulpinoidea, Eutrochium fistulosum, Juncus coriaceus, Oxypolis rigidior, Packera aurea, Parnassia grandifolia</i>, and <i>Solidago patula</i>. Occurrences are located in seepage areas underlain by limestones, dolomites, hornblende, gabbro, or gneiss at elevations ranging from about 700-1100 m (2400-3500 feet). In the Ridge and Valley of northeastern Tennessee, the examples are found at lower elevations.
