Reference:

Description:
This seepage fen is found in the United States in the Highland Rim region of middle Tennessee, southeastern Kentucky, and southern Ohio. Examples occur in calcareous seepage on flat to sloping areas associated with streams. Soils contain a thin organic layer over limestone gravel, over a less permeable layer of more solid rock. The vegetation is dominated by herbaceous plants. Characteristic species include Carex atlantica, Carex lurida, Carex leptalea ssp. harperi, Parnassia grandifolia, Juncus brachycephalus, Rudbeckia fulgida (var. umbrosa in Tennessee occurrences, var. speciosa in the Kentucky occurrence), Cardamine bulbosa, Impatiens capensis, Juncus coriaceus, Juncus effusus, Lobelia puberula, Lobelia cardinalis, Oxypolis rigidior, Phlox glaberrima, Rhynchospora capitellata, Scirpus atrovirens, Scirpus cyperinus, Solidago patula var. patula, and Thelypteris palustris var. pubescens. Woody species include Alnus serrulata, Salix humilis, Salix caroliniana, Cornus amomum, and Acer rubrum, which may invade the herbaceous seep. In the Western Highland Rim of Tennessee (Lewis, Cheatham, and Williamson counties), Xyris tennesseensis is endemic to this community and occurs in 50% or more of its occurrences. Ohio examples lack Parnassia grandifolia but are included here.
