Reference: EcoArt 2002
Description: This alliance includes tallgrass grasslands known from the Coastal Prairie and the northern Fayette Prairie in southern and southeastern Texas dominated by ~Schizachyrium scoparium var. scoparium$ and ~Paspalum plicatulum$, occurring with ~Sorghastrum nutans, Sporobolus compositus, Setaria$ spp., ~Andropogon gerardii$, and ~Muhlenbergia capillaris$. On wetter sites, ~Fimbristylis puberula, Carex$ spp., and ~Rhynchospora$ spp. become important. Typical forbs include ~Symphyotrichum ericoides (= Aster ericoides), Mimosa microphylla (= Mimosa quadrivalvis var. angustata), Neptunia lutea$, and ~Liatris$ spp. Overgrazing and fire supression of this grassland have led to the invasion of a wide variety of woody species such as ~Rosa bracteata, Acacia farnesiana, Morella cerifera (= Myrica cerifera)$, and ~Triadica sebifera (= Sapium sebiferum)$. Some of these grasslands occur on upland acidic Vertisols and Alfisols of the Coastal Prairie and on acidic Alfisols of the more inland portion of the Fayette Prairie. These areas are characterized by the occurrence of low, circular mounds called mima or pimple mounds, which add local relief to an otherwise flat topography.
