CEGL004111 Juncus (dichotomus, scirpoides) - Drosera intermedia Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Forked Rush, Needle-pod Rush) - Spoonleaf Sundew Wet Meadow
Colloquial Name: Forked Rush Dune Swale
Hierarchy Level: Association
Type Concept: This interdunal swale community of the Eastern Shore of Maryland and Virginia occurs in small, shallow, saturated depressions. Soils are characterized by a shallow organic layer overlying sands. Sedges and rushes are strongly dominant, including species such as Juncus dichotomus, Juncus canadensis, Juncus biflorus, Juncus scirpoides, Juncus acuminatus, Juncus megacephalus, Juncus canadensis, Cyperus odoratus, Scleria verticillata, Rhynchospora colorata, and Fimbristylis castanea. Common associates include several "bog-loving" species of acidic, saturated environments, including Drosera intermedia, Lycopodiella appressa, Utricularia subulata, Utricularia juncea, Fuirena pumila, Xyris jupicai, and Xyris caroliniana, as well as other herbaceous associates including Linum medium, Eupatorium hyssopifolium var. hyssopifolium, Euthamia caroliniana, Andropogon virginicus, Triadenum virginicum, and Solidago sempervirens. Examples of this association are variable in floristic composition, but can be differentiated from ~Schoenoplectus pungens - Fimbristylis (castanea, caroliniana) Marsh (CEGL004117)$$ by the strong dominance by Juncus spp. and the presence of species typical in bog settings, including Drosera intermedia, Drosera rotundifolia, Lycopodiella appressa, and others.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This community occurs in close association, and often as part of a finely textured mosaic, with ~Morella (cerifera, pensylvanica) - Vaccinium corymbosum Wet Shrubland (CEGL003906)$$ and ~Morella cerifera / Hydrocotyle verticillata Wet Shrubland (CEGL003840)$$. It is similar to ~Schoenoplectus pungens - Fimbristylis (castanea, caroliniana) Marsh (CEGL004117)$$ and may represent a successional phase.

Dynamics: No Data Available
Environmental Description: This community occupies freshwater interdunal swales with a shallow organic layer overlying sand. Groundwater is close to the surface, causing saturated hydrology, but standing water is generally present only after rain.
Geographic Range: This community occurs from New Jersey south to Virginia.
Nations: US
