Name: Panicum hemitomon Semipermanently Flooded Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This association is a very common fresh marsh type of the Chenier and Deltaic plains of Louisiana and the upper coast of Texas. This type is broadly defined to include several manifestations related to geographic location, associated vegetation, and degree of subsidence. However, all examples are strongly dominated by Panicum hemitomon. Much of the variability currently reflected in this type is exhibited between examples found in the Chenier and Deltaic plains. The Deltaic Plain expressions are largely floating marsh ("thick mat flotant"), while very little flotant is present in the Chenier Plain. Commonly occurring species in the Chenier Plain of Louisiana include Sagittaria lancifolia, Eleocharis spp., Typha spp., Cladium mariscus ssp. jamaicense (= Cladium jamaicense), Ludwigia spp., Schoenoplectus californicus (= Scirpus californicus), Crinum americanum, Zizaniopsis miliacea, and Cephalanthus occidentalis, while in the Deltaic Plain common associates include Leersia oryzoides, and sometimes Sagittaria lancifolia, along with Thelypteris palustris, Osmunda regalis, Vigna luteola, Ipomoea sagittata, Polygonum sagittatum, and Conoclinium coelestinum (= Eupatorium coelestinum).  Accession Code: VB.CC.25114.PANICUMHEMITOMO Plot-observations of this Community Concept: 0
