Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Coastal Plain Beaksedge - Large Beaksedge - Gulf Bog Panicgrass - Black-bract Pipewort - Rush-featherling Seepage Meadow

Colloquial Name: Florida Panhandle Muck Bog

Hierarchy Level:  Association

Type Concept: This is a seepage bog ("poor fen") community of the Florida Panhandle, known from Bay, Calhoun, and Gulf counties. The dominant species are Rhynchospora macra, Rhynchospora stenophylla, Panicum nudicaule, Pleea tenuifolia, Eriocaulon compressum, and Eriocaulon nigrobracteatum. Additional high-cover and/or frequent species include (in order of importance) Sarracenia psittacina, Eriocaulon decangulare, Drosera capillaris, Drosera tracyi, Hypericum brachyphyllum, Balduina uniflora, Pinguicula planifolia, Syngonanthus flavidulus, Cliftonia monophylla, Aristida palustris, and Utricularia subulata. Eriocaulon nigrobracteatum is restricted to this community. Many of the species in this community are endemic to East Gulf Coastal Plain bogs and seeps.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Based on extensive information in Orzell and Bridges (1993). Note that Panicum nudicaule is erroneously not regarded as a valid taxon in Kartesz but is included in Dichanthelium dichotomum; it also needs a name in Dichanthelium.

Environmental Description:  This is a seepage bog ("poor fen") community of the Florida Panhandle, known from Bay, Calhoun, and Gulf counties. This community occurs on black, decomposed, fluid mucks (30-220 cm deep), over coarse acidic sands or sandy clays (pH 5.4-5.6). The muck is autochthonous, having originated with the growth of sedges (Orzell and Bridges 1993). "These poor fens seem to be correlated with the escarpments of a series of Plio-Pleistocene sandy upland terraces which reflect various relict shorelines which, when dissected by perennial stream valleys, provide sufficient topographic relief to intercept groundwater stored in the unconsolidated surficial aquifer, forming poor fens" (Orzell and Bridges 1993).
Geographic Range: This seepage bog community occurs in the Florida Panhandle, from Bay, Calhoun, and Gulf counties.
