Description:
These circumneutral herbaceous seepage fens are dominated by hydrophytic plants, particularly graminoids, although shrubs are often found scattered or in thickets. Herbaceous cover is high except in areas of marly ooze. Abundant herbaceous species in Ozark examples include <i>Carex interior, Carex leptalea, Carex lurida, Impatiens capensis, Lysimachia quadriflora, Oxypolis rigidior, Rhynchospora capillacea</i>, and <i>Thelypteris palustris</i>. Shrubs include <i>Alnus serrulata, Cornus amomum, Physocarpus opulifolius, Salix caroliniana</i>, and <i>Salix humilis</i>. More elevated areas dominated by perennial grasses ("prairie-like fens") include <i>Andropogon gerardii, Castilleja coccinea, Helianthus mollis, Panicum virgatum, Rudbeckia fulgida var. umbrosa, Silphium integrifolium, Silphium terebinthinaceum, Sorghastrum nutans</i>, and <i>Veronicastrum virginicum</i>. Kentucky and middle Tennessee examples from the Interior Low Plateau contain <i>Cardamine bulbosa, Carex atlantica ssp. atlantica</i> and <i>Carex atlantica ssp. capillacea</i> (instead of <i>Carex interior), Carex leptalea ssp. harperi, Carex lurida, Impatiens capensis, Juncus brachycephalus, Juncus coriaceus, Juncus effusus, Lobelia puberula, Lobelia cardinalis, Oxypolis rigidior, Parnassia grandifolia, Phlox glaberrima, Rudbeckia fulgida var. speciosa</i> (in the Kentucky occurrence), <i>Rudbeckia fulgida var. umbrosa</i> (in Tennessee occurrences), <i>Rhynchospora capitellata, Solidago patula var. patula</i>, and <i>Thelypteris palustris var. pubescens</i>. Trees are sometimes present but never common. Examples of this alliance are found in the central and southeastern United States, including Arkansas and Missouri (Ozarks), and Kentucky and Tennessee (Interior Low Plateau).
