This shrubland association occurs on somewhat steep to steep southeast- and southwest-facing slopes at low elevations between 0 and 494 m. It is characterized by dominance to codominance of <i>Salvia leucophylla</i> with subdominance to codominance of <i>Eriogonum cinereum</i> in the shrub layer. |

This shrubland community is restricted to high-elevation, acidic bedrock exposures in the Central Appalachians of eastern West Virginia and northwestern Virginia. It occurs on upper-slope and ridgetop outcrops, pavements, and clifftops of acidic bedrock (quartzite and granitic) at elevations from about 950 to 1460 m (3100-4800 feet). Surface cover of bedrock and loose boulders averages about 80% in plot samples, and soil development is minimal. These habitats have distinctly xeric moisture regimes and are subject to year-round microclimatic extremes, including high solar exposure and temperatures in summer, high winds, periodic ice, and low winter temperatures. <i>Kalmia latifolia, Gaylussacia baccata</i>, and <i>Vaccinium</i> spp. are codominant shrubs in variable proportions, with <i>Vaccinium angustifolium</i> the principal species of high-elevation sites (all >1200 m [4000 feet]) in West Virginia and <i>Vaccinium pallidum</i> the characteristic species of somewhat lower-elevation (950-1200 [3100-4000 feet]) sites in Virginia. Other woody plants occurring frequently in the type include <i>Menziesia pilosa, Sorbus americana, Photinia melanocarpa (= Aronia melanocarpa), Gaultheria procumbens, Hamamelis virginiana, Prunus pensylvanica, Ilex montana, Nemopanthus mucronatus</i> (West Virginia only), and extremely stunted (<3 m tall) <i>Betula alleghaniensis</i>. Herbaceous plants are typically very sparse, but occasional dense colonies of <i>Deschampsia flexuosa</i> occur on open ledges with thin mats of moss and organic matter. The vegetation is floristically quite depauperate and plot-sampled stands have a mean species richness of only 15 vascular taxa. |

This association represents swamp forests along upper tidal reaches of rivers in portions of the outer Atlantic Coastal Plain ranging from southeastern Virginia and North Carolina to South Carolina, in which Nyssa biflora, Nyssa aquatica, and Taxodium distichum may dominate singly, codominate in various combinations, or share dominance with Acer rubrum, Fraxinus pennsylvanica, and/or Liquidambar styraciflua. Typical subcanopy trees are Nyssa biflora, Acer rubrum, Fraxinus pennsylvanica, Liquidambar styraciflua, Ulmus americana, and Quercus laurifolia. Woody vines are frequent and climb into the canopy; they include Decumaria barbara, Toxicodendron radicans ssp. radicans, Campsis radicans, Smilax walteri, and Berchemia scandens. Shrub and herb layers are variable but generally contain a mixture of species characteristic of both marshes and swamps. Typical shrubs are Fraxinus caroliniana, Itea virginica, Amelanchier canadensis, Leucothoe racemosa, Lyonia ligustrina var. foliosiflora, Alnus serrulata, and Morella cerifera (= Myrica cerifera var. cerifera). Characteristic herbaceous species include Saururus cernuus, Peltandra virginica, Triadenum walteri, Boehmeria cylindrica, Lycopus rubellus, Bidens discoidea, Carex seorsa, Carex stipata var. maxima, Cicuta maculata, Glyceria septentrionalis, Ranunculus sceleratus, Lobelia cardinalis, Sphenopholis pensylvanica, Decodon verticillatus, Galium obtusum, Polygonum setaceum, Osmunda regalis var. spectabilis, Scutellaria lateriflora, Hydrocotyle verticillata, Cinna arundinacea, and Pilea pumila. Substrates are mucky peats and mucks; nutrient regimes may be enhanced in some examples by rare, wind-tidal inputs. Because of higher nutrient status, this type is more diverse than non-tidal cypress-gum forests. Pronounced hummock/hollow microtopography is usually a prominent feature of this type, with the hollows filled with deep, soupy muck. |
