CEGL004341 Eragrostis hypnoides - Micranthemum umbrosum - Lipocarpha micrantha - (Juncus repens) Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Teal Lovegrass - Shade Mudflower - Small-flower Halfchaff Sedge - (Lesser Creeping Rush) Wet Meadow
Colloquial Name: Coastal Plain Blackwater Drawdown Riverbank
Hierarchy Level: Association
Type Concept: This annual-dominated community occupies drawdown banks of blackwater rivers and other seasonally flooded muddy to silty banks from Virginia to South Carolina and possibly Georgia. Annuals dominate this community and can include Eragrostis hypnoides, Lipocarpha micrantha, Fimbristylis autumnalis, Micranthemum umbrosum, Lindernia dubia var. dubia, Lindernia dubia var. anagallidea, Fimbristylis perpusilla. Perennials are also present, including Juncus repens, Helenium flexuosum, Gratiola aurea, Sabatia kennedyana, but the community is generally dominated by a sparse to dense turf of annuals, most of the cover 2-10 cm tall. Seedlings and scattered larger individuals of trees such as Betula nigra and Acer rubrum may occur. Other species present may include Bidens frondosa, Boehmeria cylindrica, Commelina diffusa, Cyperus erythrorhizos, Cyperus polystachyos, Diodia virginiana, Digitaria sanguinalis, Echinochloa muricata, Echinodorus cordifolius, Eleocharis obtusa, Erechtites hieraciifolius, Hydrocotyle verticillata var. verticillata, Hypericum mutilum, Hypoxis curtissii, Justicia ovata, Ludwigia decurrens, Ludwigia palustris, Mitreola petiolata, Oldenlandia boscii, Panicum dichotomiflorum, Panicum rigidulum var. elongatum, Panicum verrucosum, Paspalum fluitans, Pluchea camphorata, Polygonum hydropiperoides, Polygonum pensylvanicum, Rhynchospora corniculata, Rotala ramosior, Sabatia calycina, Scirpus cyperinus, and Triadenum walteri. A wide range of other species may occur, including aliens, since seeds wash into this community from a variety of sources. This community often provides habitat for globally or regionally rare plant species, many of them adapted for this unusual environment.
