Name: Schizachyrium scoparium - Andropogon gerardii - Sorghastrum nutans - Bifora americana Mollisol Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This tallgrass prairie community occurs on Mollisols in the Texas Blackland Prairie region and the Fort Worth Prairie region (Diamond and Smeins 1990). It has a greater abundance of Andropogon gerardii than the other Texas Blackland Prairie types. Within the Blackland Prairie region, this type occurs primarily on the north-to-south-oriented Whiterock Cuesta, a limestone outcrop of late Cretaceous age, while it is situated on limestone of early Cretaceous age in the Fort Worth Prairie region. In both regions mid grasses including Bouteloua curtipendula, Bouteloua hirsuta, and Nassella leucotricha are important. In the Fort Worth Prairie Bouteloua hirsuta var. pectinata (= Bouteloua pectinata) can be dominant along with Aristida spp. on rocky outcrops with a variety of xeric forbs, including species such as Hedeoma reverchonii var. reverchonii, Dyschoriste linearis, Onosmodium molle ssp. occidentale (= Onosmodium occidentale), Dalea purpurea, Dalea aurea, Dalea enneandra, and Yucca pallida. On similar sites in the Blackland Prairie region, Yucca arkansana replaces Yucca pallida (J. Eidson pers. comm.). The rock outcrop phase of this community may merit later recognition as a distinct phase when more data become available.  Accession Code: VB.CC.20404.SCHIZACHYRIUMSC Plot-observations of this Community Concept: 0
