Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Rhynchospora (alba, cephalantha) - Muhlenbergia uniflora - Lophiola aurea Fen
Colloquial Name: Pine Barrens Streamside Sedge Savanna
Hierarchy Level: Association
Type Concept: This wet meadow occurs in the Pine Barrens of New Jersey on the floodplains of Outer Coastal Plain rivers and streams. It is often found in expanses bordered by woody herbaceous savanna. Microtopography is tussocky, with dwarf Atlantic white-cedar on the low-graminoid tussocks and a remarkable diversity of herbaceous and bryophyte species on the hummocks and in the hollows. The visual impression of this community is a sedge meadow with the scattered yellow and white fuzzy flowers of Lophiola aurea and white flowers of Sabatia difformis. This community is stable in undisturbed sites as well as historically disturbed sites on a variety of substrates including peat, bog iron muck, or quartzite sand. Groundwater seepage is the primary hydrologic force with occasional riverine flooding. Dominant species include Rhynchospora alba, Rhynchospora cephalantha, Muhlenbergia uniflora, Lophiola aurea, and Sarracenia purpurea. Associated dwarf woody species include Chamaecyparis thyoides and Ilex glabra. Associated herbaceous species include Agalinis purpurea, Agrostis perennans, Andropogon glomeratus, Oclemena nemoralis, Symphyotrichum novi-belgii, Bartonia paniculata, Calamagrostis pickeringii, Calopogon tuberosus, Carex exilis, Carex livida, Cladium mariscoides, Danthonia epilis, Drosera intermedia, Eriocaulon aquaticum, Eriocaulon decangulare, Eriophorum virginicum, Juncus canadensis, Juncus pelocarpus, Lachnanthes caroliana, Lobelia canbyi, Lobelia nuttallii, Nymphaea odorata, Dichanthelium dichotomum var. ensifolium, Pogonia ophioglossoides, Polygala cruciata, Rhynchospora chalarocephala, Rhynchospora gracilenta, Rhynchospora oligantha, Sabatia difformis, Schizachyrium scoparium, Scleria reticularis, Triantha racemosa, Utricularia cornuta, Utricularia juncea, and Utricularia subulata.
