CEGL006608 Eragrostis hypnoides - Ludwigia sphaerocarpa - Polygonum hydropiperoides Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Teal Lovegrass - Globe-fruit Primrose-willow - Swamp Smartweed Marsh
Colloquial Name: Coastal Plain Teal Lovegrass Pond
Hierarchy Level: Association
Type Concept: This seasonally flooded, depressional wetland of the central Atlantic Coastal Plain occupies the lowest portion of the basin and is flooded for the longest period relative to adjacent vegetation zones. In years of high rainfall resulting in incomplete drawdown, many species of this association persist in the seedbank below standing water. The substrate is an organic layer over black clay loam. The vegetation is dominated by small-statured herbs, including Eragrostis hypnoides, Hottonia inflata, Polygonum hydropiperoides, Polygonum amphibium, Ludwigia sphaerocarpa, Oldenlandia uniflora, Cyperus strigosus, Bidens frondosa, Bidens discoidea, Fimbristylis perpusilla, Fimbristylis autumnalis, and Juncus pelocarpus. Other species of taller stature may be present, including seedlings or small saplings of Cephalanthus occidentalis and herbaceous species Panicum rigidulum, Carex striata, Carex gigantea, and Torreyochloa sp.
