Name: Bigelowia nuttallii - Krameria lanceolata - Aristida dichotoma - Sporobolus silveanus Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This terrestrial, forb-dominated community is endemic to southeastern and east-central Texas outcrops of the Catahoula Formation. The herbaceous flora of this community is diverse and displays considerable seasonal variation. Occurrences may appear almost devoid of vegetation during the dry summers, while the spring and autumn are periods of peak flowering. The best known and studied examples are found in Jasper County on Angelina National Forest. The community is dominated by prairie-like vegetation with Bigelowia nuttallii, Schizachyrium scoparium, Aristida dichotoma, Aristida longispica, Croton michauxii, Sporobolus silveanus, and Tridens strictus as primary components. Key diagnostic species of this community are typically rare elsewhere in eastern Texas, including Schoenolirion wrightii, Evolvulus sericeus, Callirhoe sp., Gratiola flava, Saxifraga texana, Bigelowia nuttallii, Liatris mucronata, Krameria lanceolata and others. Within the Pineywoods vegetation area this community occurs within a matrix of historically longleaf pine-dominated open woodlands. In Walker and Grimes counties (within the Post Oak Savanna vegetation area), this matrix vegetation is replaced by Quercus stellata woodland or savannas and may include a complex of exposed sandstone/mudstone flats and ledges, intermixed with dense, herbaceous patches, scattered, stunted trees and shrubs, and fruticose lichens. Much of the soil and rock is unvegetated.  Accession Code: VB.CC.23662.BIGELOWIANUTTAL Plot-observations of this Community Concept: 0
