Description:
This community is an open, graminoid-dominated wetland with significant cover of <i>Sphagnum</i> spp. It has a strong component of species of northern phytogeography occurring in combination with species endemic to the southern Appalachians, and in association with felsic gneisses or schists and acidic, nutrient-poor seepage. The dwarf-shrub (less than 0.5 m), <i>Vaccinium macrocarpon</i>, may be scattered throughout or be locally dominant. Typical dominants are <i>Carex echinata, Solidago patula var. patula, Carex leptalea, Carex atlantica, Rhynchospora capitellata, Scirpus atrovirens, Osmunda cinnamomea, Lysimachia terrestris, Vaccinium macrocarpon, Eriophorum virginicum</i>, and <i>Polytrichum commune</i>. Other characteristic species are <i>Arethusa bulbosa, Aulacomnium palustre, Bazzania trilobata, Calopogon tuberosus, Carex folliculata, Carex gynandra, Carex trisperma, Chelone cuthbertii, Juncus effusus, Juncus subcaudatus, Lilium grayi, Veratrum virginicum, Orontium aquaticum, Osmunda regalis var. spectabilis, Oxypolis rigidior, Parnassia asarifolia, Platanthera grandiflora, Poa paludigena, Rhizomnium appalachianum, Sagittaria latifolia, Scirpus cyperinus, Scirpus expansus, Scirpus polyphyllus, Packera aurea, Sphagnum bartlettianum, Sphagnum fallax, Sphagnum affine, Sphagnum palustre, Sphagnum recurvum, Spiraea alba, Spiraea tomentosa, Stenanthium gramineum var. robustum, Thelypteris palustris var. pubescens, Thelypteris simulata</i> (rarely), and <i>Rhizomnium appalachianum</i>. This community can occur on flat areas, in portions of valley bottoms that are not subject to flooding, but maintained hydrologically by rainwater and a high water table, or in the upper portions of stream watersheds, on slight slopes, hydrologically maintained by very nutrient-poor to fairly nutrient-rich seepage.
