Name:
Sedum spp. - Schizachyrium scoparium Comanchian Open Grassland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance accommodates specialized glade vegetation, frequently dominated by low forbs (<i>Allium drummondii, Centaurium texense, Croton monanthogynus, Houstonia micrantha, Lesquerella gordonii, Lesquerella ovalifolia, Minuartia patula, Valerianella amarella</i>), grasses (<i>Bouteloua curtipendula, Bouteloua hirsuta, Schizachyrium scoparium, Sporobolus vaginiflorus</i>), succulents (<i>Sedum nuttallianum, Sedum pulchellum, Portulaca</i> sp.), and ferns (<i>Pellaea ternifolia, Selaginella arenicola ssp. riddellii, Selaginella peruviana, Woodsia obtusa ssp. occidentalis</i>). It occurs on granite, schist, gneiss, and limestone rock outcrops in the inland (non-coastal plain) parts of Texas and adjacent Oklahoma, including the Edwards Plateau, Lampasas Cutplain, Crosstimbers, and Blackland Prairie. This vegetation may occur as large to small patches embedded in a matrix of woodlands, open forests, or perennial grass-dominated prairies. Bare rock may comprise 90% of the larger area, but vegetative cover with the patches is often 100%.
