Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bushy St. John''s-wort - Hazel Alder / Eastern Gamagrass Wet Shrubland
Colloquial Name: Alabama St. John''s-wort - Alder Wet Shrubland
Hierarchy Level: Association
Type Concept: These temporarily flooded riparian shrublands are found in the United States in the southern end of the Ridge and Valley province of Alabama. Stands occur near moderately sized rivers, on bedrock and cobble of dolomite. This community is maintained by flashy, high-velocity flows. These shrublands are of modest stature (1-3 m [3-10 feet]). The dominant shrubs are Alnus serrulata and Hypericum densiflorum var. interior. Associated shrubs and scattered short trees include Betula nigra, Catalpa bignonioides, Cephalanthus occidentalis, Cornus amomum, Diospyros virginiana, Itea virginica, Platanus occidentalis, Salix caroliniana, and Ulmus rubra. Typical species in the herbaceous layer include Anemone virginiana, Commelina virginica, Conoclinium coelestinum, Elephantopus carolinianus, Helenium autumnale, Hydrocotyle sp., Ludwigia leptocarpa, Lycopus sp., Orontium aquaticum, Oxypolis rigidior, Phlox carolina, Rhynchospora colorata, Rudbeckia laciniata, Tripsacum dactyloides, and Vernonia gigantea.
