Name: Eleocharis compressa - Schoenolirion croceum - Carex crawei - Allium cernuum Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This herbaceous seepage community is a zonal component of Central Basin (Tennessee) and Moulton Valley (Alabama) Limestone Cedar Glades. Examples are dominated by Eleocharis compressa, Schoenolirion croceum, Carex crawei, and Allium cernuum. Other characteristic species include Nothoscordum bivalve, Isoetes butleri and Hypoxis hirsuta. 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 Juniperus virginiana / Schizachyrium scoparium - (Andropogon gerardii, Sorghastrum nutans) - Silphium (trifoliatum, terebinthinaceum) Wooded Herbaceous Vegetation (CEGL004738). In contrast, Tennessee Central Basin examples are associated with Sporobolus (neglectus, vaginiflorus) - Aristida longispica - Panicum flexile - Panicum capillare Herbaceous Vegetation (CEGL004340), an annual grass glade type.  Accession Code: VB.CC.23430.ELEOCHARISCOMPR Plot-observations of this Community Concept: 0
