CEGL004340 Sporobolus (neglectus, vaginiflorus) - Aristida longespica - Panicum flexile - Panicum capillare Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Barrens Dropseed, Poverty Dropseed) - Slimspike Three-awn - Wiry Panicgrass - Witchgrass Grassland
Colloquial Name: Limestone Annual Grass Glade
Hierarchy Level: Association
Type Concept: This annual herbaceous community is a zonal component of Nashville Basin (Tennessee) and Moulton Valley (Alabama) limestone cedar glades. Much of this vegetation is a mixture of annual grasses and perennial forbs, with enormous seasonal variation in dominance. Additional associations may be named. Relations with related vegetation in other ecoregions needs further investigation. Stands are dominated by Sporobolus neglectus, Sporobolus vaginiflorus var. vaginiflorus, and/or Sporobolus vaginiflorus var. ozarkanus. Some of the co-occurring forbs are the endemic or near-endemic Dalea gattingeri and Pediomelum subacaule, along with Croton capitatus, Grindelia lanceolata, Stenaria nigricans var. nigricans, Heliotropium tenellum, Trichostema brachiatum, Manfreda virginica, and Ruellia humilis. Dalea gattingeri is present in most examples of this vegetation type. Grindelia lanceolata has become abundant in some examples; this may merit recognition as an association, or it may be a symptom of disturbance.

Floristics: Stands are dominated by Sporobolus neglectus, Sporobolus vaginiflorus var. vaginiflorus, and/or Sporobolus vaginiflorus var. ozarkanus (= Sporobolus ozarkanus). Some of the co-occurring forbs are the endemic or near-endemic Dalea gattingeri and Pediomelum subacaule, along with Croton capitatus, Grindelia lanceolata, Stenaria nigricans var. nigricans (= Hedyotis nigricans var. nigricans), Heliotropium tenellum, Trichostema brachiatum (= Isanthus brachiatus), Manfreda virginica, and Ruellia humilis. In addition, Grindelia lanceolata has become abundant in some examples. Middle Tennessee examples also include more endemic species such as Astragalus tennesseensis and Echinacea tennesseensis.
Dynamics: Grindelia lanceolata has become abundant in some examples; this may merit recognition as an association, or it may be a symptom of disturbance (Baskin and Baskin 1996).
Environmental Description: Middle Tennessee glades occur on Ordovician limestones, Moulton Valley examples on Mississippian strata.
Geographic Range: This annual herbaceous community is found in Nashville Basin (Tennessee) and Moulton Valley (Alabama).
