Description:
This herbaceous community occurs within a matrix of oak woodlands, on deep, loose, sandy soils on rolling topography, underlain by Eocene strata such as Carrizo, Queen City, and Sparta sands. It often occurs as a spectrum of seral stages, with <i>Schizachyrium scoparium</i> dominating later-successional sites, and an abundance of annual or short-lived perennial species covering earlier-successional portions. Characteristic species include <i>Schizachyrium scoparium, Lechea tenuifolia, Acalypha radians, Heliotropium racemosum, Helianthus debilis, Aristolochia erecta, Baptisia bracteata var. leucophaea, Castilleja indivisa, Cenchrus longispinus (= Cenchrus carolinianus), Chaetopappa asteroides, Chamaecrista calycioides, Chamaesyce cordifolia (= Euphorbia cordifolia), Cnidoscolus texanus, Croton capitatus, Croton glandulosus, Croton texensis, Descurainia pinnata, Dichaetophora campestris, Eriogonum annuum, Euphorbia tetrapora (= Tithymalus tetrapora), Froelichia floridana, Gaillardia pulchella, Helianthemum rosmarinifolium, Houstonia humifusa (= Hedyotis humifusa), Loeflingia squarrosa, Lupinus subcarnosus, Mentzelia nuda, Neptunia pubescens, Nuttallanthus texanus (= Linaria texana), Paronychia drummondii, Pediomelum hypogaeum var. subulatum (= Pediomelum subulatum), Pediomelum rhombifolium (= Psoralidium rhombifolium), Phlox drummondii, Phyllanthus abnormis, Rhynchosia americana, Rhynchospora harveyi, Sporobolus purpurascens, Tragia betonicifolia</i>, and <i>Tragia urticifolia</i>. A large number of narrowly distributed, endemic species are associated with this community, including <i>Abronia macrocarpa, Allium elmendorfii, Brazoria truncata var. pulcherrima (= Brazoria pulcherrima), Brazoria truncata var. truncata, Chaetopappa imberbis, Cryptantha texana, Dalea obovata, Galactia canescens, Hymenopappus carrizoanus, Lechea san-sabeana, Lesquerella grandiflora, Liatris elegans var. carizzana, Polanisia erosa ssp. breviglandulosa, Polygonella parksii, Prunus texana, Senecio ampullaceus, Sphaeralcea lindheimeri, Tephrosia lindheimeri</i>, and <i>Tetragonotheca repanda</i>.
