This community is currently known from a narrow range in the Northern Blue Ridge and adjacent inner Piedmont of Virginia, Maryland, and West Virginia. It is restricted to the western Piedmont foothills and lower- to middle-elevation slopes and spurs of the main Blue Ridge. Elevation ranges from 140 to 950 m (450-3100 feet). The type is generally associated with base-rich soils weathered from mafic igneous and metamorphic rocks, including metabasalt, amphibolite, pyroxene-bearing granulite, charnockite, and actinolite schist. It also occurs less frequently on granitic rocks and calcareous metasiltones and phyllites. Habitats are more-or-less rocky, gentle to steep, submesic to subxeric slopes with a wide range of aspects. Midslope topographic positions are typical, but stands occasionally occur on lower or upper slopes and crests. This association is a true oak-hickory forest with mixed canopy dominance by several <i>Quercus</i> spp. and <i>Carya</i> spp. In particular, <i>Carya ovalis, Quercus rubra</i>, and <i>Quercus montana</i> are consistent codominants and have the highest importance values based on standard forestry statistics generated from stem-diameter measurements. <i>Quercus alba, Quercus velutina, Carya tomentosa, Carya glabra, Fraxinus americana</i>, and <i>Liriodendron tulipifera</i> are less constant canopy species but achieve codominance in some stands. <i>Carya</i> spp., <i>Quercus</i> spp., <i>Acer rubrum, Nyssa sylvatica, Fraxinus americana</i>, and <i>Sassafras albidum</i> are well-represented in lower tree strata. <i>Cercis canadensis</i> (at lower elevations) and, to a lesser extent, <i>Cornus florida</i> dominate the shrub and lowest tree layers, while <i>Viburnum acerifolium</i> is a common low shrub. A large number of herbaceous species occur in the type. |

These low-elevation forests develop along relatively acidic soils on small streams in the Coastal Plain of Maryland and Virginia, extending west across the Virginia and North Carolina Piedmont to the Cumberland Plateau and Ridge and Valley. The topographic features of floodplains can heavily influence the makeup of individual examples of this association. The canopy, subcanopy, shrub, and herbaceous layers often are well-developed. Dominant canopy species always include <i>Liquidambar styraciflua</i> and <i>Liriodendron tulipifera</i>, while <i>Acer floridanum</i> (in the eastern part of the range), <i>Platanus occidentalis</i>, and <i>Acer rubrum var. rubrum</i> may also make up significant amounts of the canopy. This community type exists as a continuum between two subtypes, i.e., the tuliptree subtype and the sweetgum subtype. In some examples, only one or the other dominates the canopy, but in many examples, both are equally dominant. Common species in the canopy and understory include <i>Ilex opaca var. opaca, Aesculus sylvatica, Betula nigra, Carpinus caroliniana ssp. caroliniana, Cornus florida, Carya cordiformis, Fagus grandifolia, Fraxinus americana, Fraxinus pennsylvanica, Halesia tetraptera var. tetraptera, Juglans nigra, Juniperus virginiana var. virginiana, Morus rubra var. rubra, Nyssa sylvatica, Ostrya virginiana, Oxydendrum arboreum, Pinus echinata, Prunus serotina var. serotina, Quercus alba, Quercus rubra var. rubra, Ulmus rubra, Ulmus americana</i>, and <i>Ulmus alata</i>. <i>Euonymus americanus, Asimina triloba, Lindera benzoin var. benzoin</i>, and <i>Corylus americana</i> are common in the shrub layer. The herbaceous layer is species-rich and often has good sedge development. The exotics <i>Microstegium vimineum, Glechoma hederacea, Rosa multiflora, Ligustrum sinense</i>, and <i>Lonicera japonica</i> are common in this community. |

This <i>Pinus palustris</i>-dominated wet flatwoods is found in the outer Mid-Atlantic Coastal Plain of the Carolinas. Examples occur within the range of <i>Aristida stricta</i>, but lack <i>Serenoa repens</i>. Other characteristic species include <i>Vaccinium crassifolium, Pteridium aquilinum var. pseudocaudatum</i>, and <i>Gaylussacia frondosa</i>. |
