Name: Polygonum densiflorum - (Saccharum giganteum) Herbaceous Vegetation
Reference: Southeastern Ecology Working Gro...
Description: This seasonally to semipermanently flooded vegetation occurs as a band ringing the shores of ponds in the East Gulf Coastal Plain and probably adjacent provinces including the Mississippi River Valley Alluvial Plain. It is dominated by the perennial Polygonum densiflorum. Associated species include Lemna minor, Saccharum giganteum, Hydrocotyle umbellata, Saururus cernuus, Carex lupulina, Triadenum walteri, Cephalanthus occidentalis, Leersia sp., Ludwigia peploides, Boehmeria cylindrica, Juncus effusus, Rhynchospora corniculata, Ludwigia decurrens, Habenaria repens (within its range), Mikania scandens, Scirpus cyperinus, and others. At Reelfoot Lake, Tennessee (Mississippi River Alluvial Plain), this vegetation occupies the margins of ditches, sloughs, and boat channels. In some stands, Bidens laevis inhabits this community and is apparently spreading into reservoirs and impoundments in Mississippi.
