Concept: This floodplain swamp community of the Chesapeake Bay region and environs occurs in topographic depressions within alluvial floodplains. The tree canopy is dominated by Quercus palustris, Quercus phellos, Acer rubrum, and Liquidambar styraciflua. The shrub layer is of relatively low cover and comprised of Viburnum dentatum, Viburnum prunifolium, and Ilex verticillata. Vaccinium corymbosum is a less frequent shrub layer associate. Typical vines include Toxicodendron radicans, Parthenocissus quinquefolia, and Smilax rotundifolia. The herb layer is characterized by Cinna arundinacea, Boehmeria cylindrica, Symphyotrichum lateriflorum var. lateriflorum (= Aster vimineus), and Carex spp., with less frequent associates including Arisaema triphyllum, Eurybia divaricata (= Aster divaricatus), Lycopus virginicus, Ranunculus abortivus, Euonymus americana, Chasmanthium laxum, and Glyceria striata.
