CEGL008555 Polygonum spp. - Phanopyrum gymnocarpon Shoreline Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Smartweed species - Savanna Panicgrass Shoreline Wet Meadow
Colloquial Name: Southern Smartweed - Savanna Panicgrass Shoreline Wet Meadow
Hierarchy Level: Association
Type Concept: This association is documented from an herbaceous slough of the Alabama River at Haines Island in Monroe County, Alabama. It is a seasonally or perhaps semipermanently flooded herbaceous marsh with some beaver activity. There are very sparse widely scattered trees of Taxodium distichum and Salix nigra, and shrubs of Cephalanthus occidentalis, Salix nigra, Acer saccharinum, and Populus deltoides. The dominant plants are all herbaceous, most dominant are Polygonum spp. and Phanopyrum gymnocarpon; near dominant taxa (in decreasing order) include Sagittaria latifolia, Sesbania vesicaria, Lycopus spp., Alternanthera philoxeroides, Mimulus sp., Saururus cernuus, Cyperus sp., Bidens sp., Boehmeria cylindrica, Triadenum walteri, Polygonum punctatum, Strophostyles helvola, Ludwigia decurrens, and Ludwigia sp. This association is expected to occur elsewhere in open bottomland sloughs in the Coastal Plain within the range of Phanopyrum gymnocarpon, from North Carolina to northern Florida, Arkansas, and southeastern Texas. This association is distinguished from others in the same alliance by the codominance of Phanopyrum gymnocarpon with Polygonum spp.

Environmental Description: This association is documented from an herbaceous slough of the Alabama River at Haines Island in Monroe County, Alabama. It is a seasonally or perhaps semipermanently flooded herbaceous marsh with some beaver activity. This association is expected to occur elsewhere in open bottomland sloughs in the Coastal Plain within the range of Phanopyrum gymnocarpon, from North Carolina to northern Florida, Arkansas, and southeastern Texas. It could be in open sloughs in a floodplain of a brownwater river forested with Taxodium distichum, Salix nigra, Acer saccharinum, and/or Populus deltoides. This type could occur in large or small rivers.
Geographic Range: This association is documented from an herbaceous slough of the Alabama River at Haines Island in Monroe County, Alabama.
