Name: Eleocharis (bifida, compressa) - Schoenolirion croceum - Carex crawei - Allium cernuum Seep Grassland Reference: NatureServe Biotics 2019 Description: This herbaceous seepage community is a zonal component of Central Basin (Tennessee) and Moulton Valley (Alabama) Limestone Cedar Glades. Examples are dominated by <i>Eleocharis bifida, Eleocharis compressa, Schoenolirion croceum, Carex crawei</i>, and <i>Allium cernuum</i>. Other characteristic species include <i>Nothoscordum bivalve, Isoetes butleri</i> and <i>Hypoxis hirsuta</i>. This vegetation is supported by seepage of groundwater from unconfined aquifers during winter and spring. Tennessee occurrences are on Ordovician limestone, Alabama ones on Mississippian Bangor limestone. Alabama Moulton Valley examples are apparently associated with ~<i>Juniperus virginiana / Schizachyrium scoparium - (Andropogon gerardii, Sorghastrum nutans) - Silphium terebinthinaceum</i> Wooded Grassland (CEGL004738)$$. In contrast, Tennessee Central Basin examples are associated with ~<i>Sporobolus (neglectus, vaginiflorus) - Aristida longespica - Panicum flexile - Panicum capillare</i> Grassland (CEGL004340)$$, an annual grass glade type.  Accession Code: urn:lsid:vegbank.org:commConcept:33012-{31EE42A1-FE00-4AB1-BBAA-3F00D5501B2E} Plot-observations of this Community Concept: 0
