Ludwigia peploides Aquatic Vegetation
Translated Name: Floating Primrose-willow Aquatic Vegetation
Common Name: Floating Primrose-willow Aquatic Vegetation
Unique Identifier: CEGL007835
Classification Approach: International Vegetation Classification (IVC)
Summary: These floating or stranded mats of Ludwigia peploides (including ssp. glabrescens and/or ssp. peploides) occur in shallow water of flats in slow-moving streams, shallow lakes, natural and artificial impoundments. Some common associates include Ammannia spp., Callitriche spp., Hydrolea quadrivalvis, Lycopus spp., Proserpinaca spp., Veronica spp., and other mat-forming obligate wetland species. Oklahoma associates include Cephalanthus occidentalis, Hibiscus laevis, Nelumbo lutea, Polygonum hydropiperoides, and Sagittaria latifolia.

Distribution
Color legend for Distribution Map
United States Distribution: AL, AR, FL, GA, KY, LA, MS, OK, TN, TX, WV
Global Distribution: United States
Global Range: This vegetation would be expected to occur in the Coastal Plain and adjacent interior provinces from possibly Georgia south and west to Texas, in the Upper Coastal Plain at least to Kentucky, in the Central Basin of Tennessee, and west to eastern and central Oklahoma. The nominal species is recorded from some states to the north to this projected range, but its occurrence there may be sporadic or of limited extent. It is found in Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, Oklahoma, Tennessee, and Texas, and possibly Arkansas (?).
