Description: This shrubland alliance occurs on sandy sites in north-central and south-central New Mexico. Stands occur in both stabilized deep sand and areas near active dunes. Vegetation included in this alliance is characterized by a sparse woody layer dominated by the xeromorphic evergreen shrub ~Poliomintha incana$ with ~Artemisia filifolia$ present to codominant. The two different habitats produce stands with different associated species. Stabilized deep sand sites in northern New Mexico have higher shrub diversity with scattered ~Juniperus monosperma$ and ~Pinus edulis$ trees. Common shrubs and dwarf-shrubs include ~Gutierrezia sarothrae, Brickellia californica, Ericameria nauseosa var. bigelovii (= Chrysothamnus nauseosus ssp. bigelovii$, and the cacti ~Opuntia phaeacantha$ and ~Opuntia polyacantha$. The perennial grasses ~Bouteloua gracilis, Sporobolus cryptandrus$ and~Schizachyrium scoparium$ dominate the sparse herbaceous layer. The stands described from the dune area have a sparse herbaceous layer that is dominated by perennial graminoids like ~Sporobolus flexuosus$ or by annual forbs, such as ~Chamaesyce parryi$, that are seasonally present to abundant in wet years. Weedy annual forbs like ~Amaranthus$ spp., ~Dimorphocarpa wislizeni (= Dithyrea wislizeni)$, and the exotic ~Conyza canadensis$ are common. Diagnostic of this alliance is the relatively sparse shrub layer dominated by ~Poliomintha incana$.
