Description: This alliance is widely distributed in the eastern United States. Stands are dominated by broad-leaved deciduous trees and well-developed shrub and herbaceous strata. They are characterized by dense growth and a great diversity of species. Basal area can reach 40-42 m2/ha. ~Acer rubrum$ and ~Fraxinus pennsylvanica$ are consistently abundant overstory species, but ~Fraxinus profunda$ (in the southern parts of this alliance's range), ~Liquidambar styraciflua, Quercus lyrata, Quercus bicolor$, and ~Ulmus americana$ occur almost as frequently, and ~Nyssa aquatica$ and ~Taxodium distichum$ occur sporadically in the southern parts of this alliance's range. ~Acer saccharinum$ may dominate in parts of the range. The shrub layer can include a diverse mixture including ~Carpinus caroliniana, Cephalanthus occidentalis, Forestiera acuminata$, and ~Ilex decidua$, but ~Itea virginica$ is characteristic of southern stands of this alliance. Even with dense shading, the herbaceous layer is usually well-developed, displaying a preponderance of ~Boehmeria cylindrica, Carex$ spp., ~Glyceria$ spp., ~Juncus$ spp., ~Laportea canadensis, Leersia$ spp., and ~Pilea pumila$. ~Vitis$ spp. are characteristic vines of this community, but ~Toxicodendron radicans$ and ~Campsis radicans$ are also prominent. ^Sites which support stands of this alliance have level or nearly level soils that formed in water-deposited clayey or loamy sediments on floodplains of the Mississippi and other rivers and large perennial streams in the Coastal Plain. These soils are flooded or saturated for a significant portion of the growing season, and water may be ponded for most of the year in shallow depressions. Flooding can reach 1 m. Flooding occurs during the winter and spring and often extends into the growing season.
