Description:
This association accommodates herbaceous alluvial wetlands in which <i>Carex torta</i> is a dominant or characteristic species. It occupies sand, gravel, and rock bars along small rivers and streams in valleys and gorges in the Southern Appalachians, ranging west into the Cumberland Plateau and the Interior Low Plateau, and north into the Central Appalachians, Allegheny Mountains, and Piedmont. This association is characterized by light-requiring, tough-rooted herbaceous perennials tolerant of frequent inundation and flood-scouring. <i>Carex torta</i> often forms dense, extensive colonies. Associated species vary with geography but can include <i>Polygonum sagittatum, Dichanthelium clandestinum, Solidago rugosa ssp. aspera, Juncus effusus, Equisetum arvense, Onoclea sensibilis, Vernonia noveboracensis, Lycopus virginicus, Lobelia cardinalis, Symphyotrichum dumosum (= Aster dumosus), Lycopus virginicus, Osmunda regalis, Hypericum mutilum, Eupatorium fistulosum, Solidago patula, Boehmeria cylindrica, Amphicarpaea bracteata, Acalypha rhomboidea, Hypericum mutilum, Impatiens capensis, Leersia oryzoides</i>, and <i>Symphyotrichum lateriflorum (= Aster lateriflorus)</i>. Physiognomy of this type varies from strictly herbaceous to wooded herbaceous to shrubby. Scattered shrubs and small, battered specimens of <i>Platanus occidentalis, Betula nigra, Cornus amomum, Alnus serrulata</i>, and <i>Carpinus caroliniana</i> are present in some stands. An overhanging canopy may include <i>Platanus occidentalis, Betula alleghaniensis var. alleghaniensis</i>, or <i>Acer rubrum</i>. Overhanging shrubs often include <i>Rhododendron maximum</i>. Stands in disturbed landscapes may be heavily invaded by <i>Microstegium vimineum, Polygonum caespitosum var. longisetum</i>, and other weedy exotics.
