Name: Schismus (arabicus, barbatus) - (Eriogonum deflexum) Ruderal Grassland Reference: NatureServe Biotics 2019 Description: This association is currently described only from the Mojave Desert Network; it is also reported from Grand Canyon National Park. Additional global information will be added as it becomes available. It is found in disturbed areas, such as cleared roadsides, lake drawdown zones, and grazed areas, with samples from northern Lake Mead National Recreation Area, Nevada. It occurs at low elevations (ranging from approximately 350-400 m and averaging 378 m). Slopes are somewhat steep (21°). It is found primarily on low slopes at flat or southwesterly aspects. Soils are sand, and are derived typically from sandstone. Vegetation forms an open herb layer in which the herbaceous cover ranges from 4 to 24%. The tree layer is usually absent, and the shrub layer is sparse and ranges from 0 to 3% cover. <i>Schismus</i> spp. is dominant in the herbaceous layer, while <i>Eriogonum deflexum</i> is characteristically present and/or codominant. Other commonly associated herbs include <i>Camissonia brevipes, Chorizanthe brevicornu, Cryptantha micrantha, Langloisia setosissima, Malacothrix glabrata, Plantago ovata</i>, and <i>Salsola</i> spp. Shrubs that are often present include <i>Tamarix ramosissima</i>. Those shrubs sometimes present include <i>Ambrosia dumosa, Larrea tridentata, Salix tracyi, Stephanomeria pauciflora</i>, and <i>Tiquilia latior</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:37549-{CFB25BBC-A405-4212-A5C0-15BA05B25540} Plot-observations of this Community Concept: 0
