G192 Prosopis glandulosa var. glandulosa - Ziziphus obtusifolia Scrub Group
Type Concept Sentence: This Comanchian scrub woodland group is dominated or codominated by Prosopis glandulosa var. glandulosa, Dalea formosa, and Mimosa borealis and is known from the rolling plains of Texas and Oklahoma, the Edwards Plateau as well as the Chihuahuan Desert regions of Texas.
Common (Translated Scientific) Name: Honey Mesquite - Lotebush Scrub Group
Colloquial Name: Comanchian Mesquite - Mixed Scrub
Hierarchy Level: Group
Type Concept: This scrub woodland group ranges from the High, Rolling, and Red Bed plains of Texas and Oklahoma south into parts of the Edwards Plateau and Chihuahuan Desert regions of Texas. The open to closed canopy is dominated or codominated by Prosopis glandulosa var. glandulosa or low-statured shrubs such as Dalea formosa and Mimosa borealis. Associated species can include Ziziphus obtusifolia, Quercus fusiformis, Sideroxylon lanuginosum, Aloysia gratissima, Mahonia trifoliolata, Yucca glauca, Opuntia spp., Acacia greggii, Mimosa spp., Rhus lanceolata, Nassella leucotricha, Bouteloua curtipendula, Bouteloua gracilis, Bouteloua hirsuta, Bouteloua dactyloides, Schizachyrium scoparium, Ruellia nudiflora, Croton monanthogynus, Rhynchosia senna, and Indigofera miniata.
Diagnostic Characteristics: Deciduous scrubby woodlands and shrublands in the High Plains, Rolling Plains, Red Bed Plains, Edwards Plateau and Stockton Plateau regions of the south-central U.S.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Classification of this group is complicated because it may be difficult to distinguish from compositionally and structurally similar ruderal vegetation. This group as described does not include vegetation characterized by Prosopis glandulosa var. glandulosa occurring in southern Texas. Vegetation in this group is poorly described and classification of this group is hindered by the paucity of USNVC classification information at the association level. Its separation from ~Comanchian Oak - Juniper Scrub Group (G191)$$ is based on the dominance of evergreen versus deciduous shrubs and short-statured trees, a distinction that may be better made at the alliance level. The relationship of this vegetation to that included in ~Prosopis glandulosa Shortgrass Prairie Ruderal Scrub Alliance (A3952)$$ in ~Great Plains Shortgrass Prairie Group (G144)$$ needs further reconciliation.

Physiognomy and Structure: The physiognomy of this group ranges from an open short woodland to a shrubland. Due to the small size of the leaflets, light can reach the floor even through more closed canopies of Prosopis glandulosa.
Floristics: The canopy of this group is dominated by Prosopis glandulosa var. glandulosa or low-statured shrubs such as Dalea formosa and Mimosa borealis. Other canopy components may include Quercus fusiformis, Ziziphus obtusifolia, and Sideroxylon lanuginosum. The understory may contain a variety of dry-xeric shrubs, including Acacia greggii, Aloysia gratissima, Mahonia trifoliolata, Mimosa spp., Opuntia spp., Rhus lanceolata, and Yucca glauca. The herbaceous layer is typically continuous and dominated by graminoids such as Bouteloua curtipendula, Bouteloua gracilis, Bouteloua hirsuta, Bouteloua dactyloides (= Buchloe dactyloides), Nassella leucotricha, and Schizachyrium scoparium.
Dynamics: No Data Available
Environmental Description: This group occurs on a variety of soil types but is well-developed on coarse soils.
Geographic Range: This scrub woodland group ranges from the High, Rolling, and Red Bed plains of Texas and Oklahoma south into parts of the Edwards Plateau and Chihuahuan Desert regions of Texas.
