CEGL004346 Sedum pulchellum - Phemeranthus calcaricus - Leavenworthia spp. / Nostoc commune Limestone Glade Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Widow''s-cross - Limestone Fameflower - Gladecress species / Common Nostoc Limestone Glade Vegetation
Colloquial Name: Interior Low Plateau Limestone Glade Ephemeral Pool
Hierarchy Level: Association
Type Concept: This herbaceous community is a zonal component of Nashville Basin (Tennessee) and Moulton Valley (Alabama) Cedar Glades. This vegetation characteristically occupies depressions in the limestone which hold water in the winter and early spring. These areas become desiccated and baked in the heat of summer. Characteristic plants are the annuals Sedum pulchellum and Leavenworthia spp., and the perennial Phemeranthus calcaricus. The characteristic endemic Leavenworthia spp. in Tennessee are Leavenworthia stylosa, Leavenworthia torulosa, and Leavenworthia exigua. The blue-green alga Nostoc commune forms mats. Related vegetation is found in Simpson and Warren counties of Kentucky.
