Schizachyrium scoparium - Rudbeckia missouriensis - Grindelia lanceolata - (Liatris punctata var. mucronata) Grassland

NatureServe Biotics 2019
Description:
This upland prairie of the West Gulf Coastal Plain of Texas and western Louisiana occurs in small, isolated patches on calcareous soils derived from the Fleming geologic formation. This herbaceous community is dominated by graminoids, composites, and legumes, with occasional emergent woody growth. Dominant and characteristic species in forb-dominated occurrences are locally variable but may include <i>Dalea compacta var. compacta, Rudbeckia missouriensis, Rudbeckia hirta, Acacia angustissima, Liatris punctata var. mucronata, Eustoma exaltatum ssp. russellianum, Grindelia lanceolata, Agalinis heterophylla, Stenosiphon linifolius, Carex microdonta, Carex cherokeensis, Neptunia lutea, Indigofera miniata, Salvia azurea, Palafoxia reverchonii, Onosmodium bejariense var. occidentale, Liatris punctata var. mucronata</i>, and <i>Euphorbia bicolor</i>. Occurrences rich in graminoids are dominated by <i>Sorghastrum nutans</i>, and <i>Schizachyrium scoparium</i>. The combination of periodic fire, soil chemistry, and physical properties is thought to be important in maintaining this community in a landscape otherwise historically dominated by forests.
