Name: Eleocharis bifida - Eleocharis compressa - Nothoscordum bivalve Alkaline Rocky Seep Alliance Reference: NatureServe Biotics 2019 Description: This herbaceous alliance is a zonal component of limestone cedar glades in the Central Basin of Tennessee and the Moulton Valley of Alabama, as well as similar limestone glade vegetation in Kentucky, Georgia, and Arkansas. Examples are dominated by some combination of <i>Allium cernuum, Carex crawei, Dalea foliosa, Eleocharis bifida, Eleocharis compressa, Ludwigia microcarpa, Mecardonia acuminata, Mitreola petiolata, Rudbeckia triloba</i>, and <i>Schoenolirion croceum</i>. Other species present may include <i>Isoetes butleri</i> and <i>Hypoxis hirsuta</i>. Kentucky examples lack <i>Schoenolirion croceum</i>, but this species may be a late-April aspect dominant in Tennessee and Alabama examples. This alliance occurs in rocky washes and small areas along ephemeral streams or where seasonal seepage of unconfined aquifers emerges during the winter and spring, and supports a distinctive assemblage of mostly graminoid vegetation. Sites are seasonally saturated, becoming drier during the heat of summer.  Accession Code: urn:lsid:vegbank.org:commConcept:38234-{B57CFD4C-3192-4498-8503-E729914CC5E6} Plot-observations of this Community Concept: 0
