Description:
This community occupies wide, poorly drained belts of quaking muck soils, interspersed with pools of stagnant water in the Post Oak Savanna region of east-central Texas. Examples in good condition are herb-dominated and open in aspect. Most shrub and tree growth is confined to the bog margins, although <i>Morella cerifera</i> is fairly abundant throughout, except in the deepest portions of the interior. Open portions of the bog margins are dominated by sedges, grasses, and rushes. In the absence of fire, certain shrubs become much more abundant, especially <i>Alnus serrulata</i> and <i>Viburnum nudum</i>. Dominant herbaceous species in openings on bog edges include <i>Agrostis hyemalis, Andropogon virginicus, Axonopus fissifolius, Eleocharis acicularis, Eleocharis melanocarpa, Eleocharis tuberculosa, Saccharum giganteum, Juncus dichotomus, Juncus nodatus, Panicum brachyanthum, Steinchisma hians, Dichanthelium dichotomum, Dichanthelium scoparium, Panicum virgatum</i>, and <i>Paspalum laeve</i>. Wetter areas support occasional clumps of <i>Sphagnum</i> spp. and <i>Drosera brevifolia</i>, both of which tend to be absent from the interior portion of the bogs. The bog interior is dominated by the following sedges and rushes through late spring: <i>Eleocharis melanocarpa, Eleocharis tuberculosa, Eleocharis acicularis, Carex lurida, Juncus effusus, Juncus dichotomus, Juncus nodatus</i>, and <i>Juncus diffusissimus</i>. <i>Triadenum virginicum</i> and <i>Ludwigia</i> spp. may also be evident. Later in the year, <i>Helianthus angustifolius, Doellingeria umbellata, Eupatorium perfoliatum</i>, and <i>Symphyotrichum dumosum var. dumosum</i> become dominant. <i>Andropogon glomeratus</i> may be common in some bogs, and tall patches of <i>Saccharum giganteum, Panicum anceps</i>, and <i>Panicum virgatum</i> may also be rather abundant. Other characteristic or distinctive species of this community type are <i>Sarracenia alata, Burmannia capitata, Eriocaulon decangulare var. decangulare, Iris virginica, Mayaca fluviatilis, Pogonia ophioglossoides, Calopogon tuberosus, Asclepias rubra, Hypericum mutilum, Utricularia cornuta</i>, and <i>Ludwigia alternifolia</i>. Unusual species include <i>Cladium mariscoides, Eriocaulon koernickianum, Rhynchospora chalarocephala, Zigadenus densus, Cinna arundinacea, Symphyotrichum puniceum var. scabricaule</i>, and <i>Polygala sanguinea</i>.
