Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bristly-stalked Sedge - Largeleaf Grass-of-Parnassus - Leathery Rush - Roundleaf Goldenrod Ridge & Valley Herbaceous Seep
Colloquial Name: Southern Ridge & Valley Dolomite Slope Fen
Hierarchy Level: Association
Type Concept: 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 Thuja occidentalis-dominated woodlands. Species present include Carex leptalea, Carex sp., Solidago patula, Oxypolis rigidior, Juncus coriaceus, Eutrochium fistulosum, Parnassia grandifolia, Packera aurea, Coreopsis tripteris, Silphium trifoliatum var. latifolium, Viola cucullata, Lobelia siphilitica, Trautvetteria caroliniensis, and seedlings of Thuja occidentalis. Cypripedium reginae 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 Scytonema spp. cover part of the exposed rock surface; Sphagnum spp. are absent. Adjacent shrubs, which may intrude on some examples, include Toxicodendron radicans, Hydrangea sp., Cornus alternifolia, Ribes sp., Lindera benzoin, and Viburnum prunifolium.

Floristics: This saturated herbaceous vegetation occurs in a matrix of saturated Thuja occidentalis-dominated woodlands. Species present include Carex atlantica ssp. capillacea, Carex leptalea, Carex lurida, Carex scoparia, Carex stipata, Carex stricta, Carex virescens, Carex vulpinoidea, Solidago patula, Oxypolis rigidior, Cardamine bulbosa, Juncus coriaceus, Eutrochium fistulosum (= Eupatorium fistulosum), Parnassia grandifolia, Packera aurea (= Senecio aureus), Coreopsis tripteris, Silphium trifoliatum var. latifolium, Viola cucullata, Lobelia siphilitica, Trautvetteria caroliniensis, Osmunda regalis, and seedlings of Thuja occidentalis. Cypripedium reginae is present in some examples, or in the woodlands on the margins of the herbaceous openings. Cystopteris bulbifera may also be a component at some sites, but this needs to be further investigated. Marl-forming Scytonema spp. cover part of the exposed rock surface; Sphagnum spp. are absent. Adjacent shrubs, which may intrude on some examples, include Toxicodendron radicans, Hydrangea sp., Cornus alternifolia, Ribes sp., Lindera benzoin, and Viburnum prunifolium.
Dynamics: Vegetation is denser on shallow shelves of rock where organic matter collects. Cover of vascular plants varies from about 30% in relatively sparse examples to about 70% in denser ones.
