Name: Carex leptalea - Parnassia grandifolia - Juncus coriaceus - Solidago patula Ridge and Valley Herbaceous Seep Reference: NatureServe Biotics 2019 Description: This saturated herbaceous vegetation occurs on steep slopes over limestones or dolomites in the Ridge and Valley of northern Tennessee. Cover of vascular plants varies from about 30% in relatively sparse examples to about 70% in denser ones. It occurs in a matrix of saturated <i>Thuja occidentalis</i>-dominated woodlands. Species present include <i>Carex leptalea, Carex</i> sp., <i>Solidago patula, Oxypolis rigidior, Juncus coriaceus, Eutrochium fistulosum, Parnassia grandifolia, Packera aurea, Coreopsis tripteris, Silphium trifoliatum var. latifolium, Viola cucullata, Lobelia siphilitica, Trautvetteria caroliniensis</i>, and seedlings of <i>Thuja occidentalis</i>. <i>Cypripedium reginae</i> is present in some examples, or in the woodlands on the margins of the herbaceous openings. Vegetation is denser on shallow shelves of rock where organic matter collects. Marl-forming <i>Scytonema</i> spp. cover part of the exposed rock surface; <i>Sphagnum</i> spp. are absent. Adjacent shrubs, which may intrude on some examples, include <i>Toxicodendron radicans, Hydrangea</i> sp., <i>Cornus alternifolia, Ribes</i> sp., <i>Lindera benzoin</i>, and <i>Viburnum prunifolium</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:33713-{8737595A-7C7A-42BA-967F-59577DA9643A} Plot-observations of this Community Concept: 3
