This association occurs in eastern Georgia on sandy loam soils. <i>Pinus palustris</i> forms an open to closed canopy. A scrub oak stratum of <i>Quercus incana, Quercus stellata, Quercus margarettiae</i>, and (less typically) <i>Quercus laevis</i> can manifest itself as a subcanopy or as a shrub layer, depending on fire regime, and occasional individuals may reach the canopy. The shrub layer can be sparse to dense, and contains <i>Castanea pumila, Ceanothus microphyllus, Diospyros virginiana, Gaylussacia dumosa (= var. dumosa), Lyonia mariana, Morella cerifera (= Myrica cerifera var. pumila), Serenoa repens, Vaccinium myrsinites</i>, and scrub oak sprouts. Dominants of the herbaceous stratum include <i>Sporobolus curtissii, Aristida beyrichiana</i>, and <i>Sporobolus junceus</i>. Other characteristic herbs include abundant and diverse legumes, <i>Sericocarpus tortifolius (= Aster tortifolius), Symphyotrichum walteri (= Aster walteri), Baptisia perfoliata, Cnidoscolus stimulosus, Crotalaria rotundifolia, Desmodium</i> spp., <i>Dyschoriste oblongifolia, Eriogonum tomentosum, Eryngium yuccifolium var. synchaetum, Eupatorium album, Euphorbia exserta, Galactia</i> spp., <i>Ionactis linariifolius, Lespedeza</i> spp., <i>Pityopsis</i> spp., <i>Pteridium aquilinum var. pseudocaudatum, Pterocaulon pycnostachyum, Rhynchosia difformis, Rhynchosia reniformis, Salvia azurea, Solidago odora var. odora</i>, and <i>Vernonia pulchella</i>. |

This ombrotrophic late-successional wetland occurs on slightly domed peat deposits in the Allegheny Mountains region of West Virginia, at elevations between 960 and 1030 m. It is characterized by well-developed hummocks of mosses and lichens with occasional dominance by clonal patches of <i>Andromeda polifolia var. glaucophylla</i>. It is a small-patch type (0.05-10 hectares) that occupies flat-lying headwater basins in the center of wetland mosaics, where it is isolated from seepage inputs. Hummock-and-hollow microtopography is well-developed, with rounded peat hummocks ranging from 25-50 cm in height. The substrate is poorly drained peat, with depths ranging from 2 to 3.5 m. According to carbon dating of peat, this community grows on a site that has been characterized by bog vegetation for about 9500 years. The short-shrub stratum ranges from 0 to 60% cover and is almost exclusively composed of <i>Andromeda polifolia var. glaucophylla</i>, with infrequent very low cover by <i>Photinia melanocarpa</i> or <i>Hypericum densiflorum</i>. The dwarf-shrub layer is comprised of <i>Rubus hispidus</i> and <i>Vaccinium oxycoccos</i> with an average cover of 12%. The herbaceous layer, with mean 5% cover, is characterized by <i>Eriophorum virginicum</i>, which grows on top of the hummocks. <i>Rhynchospora alba</i> may line the hollows, and very low cover of <i>Carex trisperma var. trisperma</i> or <i>Osmunda cinnamomea var. cinnamomea</i> may be present. Nonvascular plants average 95% cover, with hummocks dominated by <i>Polytrichum strictum</i> and <i>Cladina</i> spp. (<i>Cladina arbuscula (= Cladonia arbuscula), Cladina rangiferina (= Cladonia rangiferina), Cladina stygia (= Cladonia stygia)</i>), and hollows lined with <i>Sphagnum</i> spp. (<i>Sphagnum rubellum, Sphagnum flexuosum, Sphagnum magellanicum</i>). Mean species richness of all vascular plants and any nonvascular plants with cover >1% is 13 taxa per 400 square meters, with 40% of the diversity in the nonvascular stratum. |
