Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pickerelweed - Green Arrow-arum Marsh
Colloquial Name: Pickerelweed - Green Arrow-arum Marsh
Hierarchy Level: Association
Type Concept: This type includes very wet or partially submerged forb vegetation of rivershores and lakeshores, and sometimes of artificial ponds, lakes, and impoundments of the southeastern United States. Examples are typically dominated by some combination of Pontederia cordata and Peltandra virginica. Associates may include Nuphar advena, Glyceria striata, Schoenoplectus tabernaemontani, Schoenoplectus americanus, and Sagittaria latifolia. On the Natchez Trace Parkway of Mississippi, the herbaceous layer is overwhelmingly dominated by Peltandra virginica; additional herbs may include Hibiscus moscheutos, Panicum virgatum, Polygonum convolvulus, Polygonum pensylvanicum, and vines of Nekemias arborea and Apios americana. In addition, there may be scattered shrubs, including Cephalanthus occidentalis, Rubus argutus, and Sambucus nigra ssp. canadensis.
