Description:
This association is an intermediate fen overlying deep peat accumulations of lakes and other depressions in the Great Lakes region east to the northeastern United States. It is characterized by rhizomatous sedges that form a mat, with variable shrub cover. Typical sedges include <i>Carex lasiocarpa, Carex prairea, Carex leptalea, Carex stricta, Carex buxbaumii, Carex flava, Carex cryptolepis, Carex lacustris, Carex livida, Carex aquatilis, Cladium mariscoides, Trichophorum alpinum, Eleocharis elliptica</i>, as well as <i>Vaccinium macrocarpon</i> and <i>Vaccinium oxycoccos</i>. Other herbaceous associates include <i>Carex rostrata, Carex trisperma, Eleocharis rostellata, Muhlenbergia glomerata, Rhynchospora alba, Schoenoplectus acutus, Typha latifolia, Doellingeria umbellata, Drosera rotundifolia, Iris versicolor, Osmunda regalis, Parnassia glauca, Pogonia ophioglossoides</i>, and <i>Thelypteris palustris</i>. Shrubs are generally confined to hummocks, but cover varies among occurrences and can exceed 25%. Characteristic species include <i>Myrica gale, Dasiphora fruticosa ssp. floribunda, Betula pumila, Salix candida, Rhamnus alnifolia, Alnus</i> spp., and <i>Cornus sericea</i>. <i>Larix laricina</i> may occur as scattered individuals atop hummocks. Hollows and channels often support <i>Utricularia intermedia, Utricularia gibba, Menyanthes trifoliata</i>, and <i>Lobelia kalmii</i>. Other herbs include <i>Symphyotrichum boreale</i> and <i>Sarracenia purpurea</i>.
