Type Concept: These temporarily flooded shrublands are found in the United States in the southern end of the Ridge and Valley province of Alabama. Stands occur in linear zones along small streams (2-5 m wide), on bedrock and cobble of dolomite. Locally, seepy and saturated patches develop. This community is maintained by occasional flash floods. These shrublands are of modest stature (1-3 m [3-10 feet]). The dominant shrubs are Hypericum densiflorum var. interior and Alnus serrulata. Associated shrubs and small trees include Liriodendron tulipifera, Cercis canadensis var. canadensis, Cornus amomum, Hydrangea quercifolia, Itea virginica, Juniperus virginiana var. virginiana, Morella cerifera, Rhus glabra, and Bignonia capreolata. Typical species in the herbaceous layer include Adiantum capillus-veneris, Aruncus dioicus, Symphyotrichum pilosum, Chelone glabra, Elymus virginicus, Eutrochium fistulosum, Fuirena squarrosa, Helenium autumnale, Helianthus angustifolius, Jamesianthus alabamensis, Juncus coriaceus, Marshallia trinervia, Mitreola petiolata, Oxypolis rigidior, Parnassia grandifolia, Phlox glaberrima, Nasturtium officinale, Rudbeckia fulgida, Rudbeckia laciniata, Trautvetteria caroliniensis, and Xyris tennesseensis.
