This alliance, concentrated in boreal regions of eastern Canada, southward to the north-central and northeastern United States, is composed of rich and moderately rich fens. The vegetation is dominated by sedges, with ericaceous shrubs, small trees, and forbs also common. <i>Carex lasiocarpa</i> is a characteristic dominant in many stands. Other characteristic and often abundant graminoids include <i>Calamagrostis canadensis, Carex aquatilis, Carex buxbaumii, Rhynchospora alba, Rhynchospora capillacea</i>, and <i>Trichophorum cespitosum</i>. Typical shrubs include <i>Andromeda polifolia, Betula pumila, Dasiphora fruticosa ssp. floribunda, Kalmia polifolia</i>, and <i>Vaccinium oxycoccos</i>. Small <i>Larix laricina</i> and <i>Picea mariana</i> are also common. Forbs that can occur in stands of this alliance include <i>Comarum palustre, Drosera rotundifolia, Equisetum fluviatile, Lobelia kalmii, Menyanthes trifoliata, Sarracenia purpurea</i>, and <i>Utricularia</i> spp. <i>Decodon verticillatus</i> is common in southern stands of this alliance. <i>Sphagnum</i> spp. form an incomplete moss layer. Stands are found on shallow to deep peat, often in areas of calcareous groundwater. Some stands occur on floating peat mats. The groundwater is slightly acidic to circumneutral and minerotrophic to moderately minerotrophic.
