CEGL004219 Muhlenbergia reverchonii - Bouteloua curtipendula - Desmanthus velutinus Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Seep Muhly - Sideoats Grama - Velvet Bundleflower Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found in mesic areas, often along ephemeral streams or adjacent to more permanent streams on the Edwards Plateau and Lampasas Cutplain of central Texas. The vegetation is dominated by Muhlenbergia reverchonii. Other graminoid species include Eleocharis sp., Cyperus sp., Schizachyrium scoparium, Bouteloua curtipendula, Aristida purpurea, Sorghastrum nutans, Tridens albescens, and Bothriochloa laguroides. Forbs include Symphyotrichum ericoides, Lythrum californicum, Desmanthus illinoensis, Bifora americana, Scutellaria drummondii, Monarda citriodora, Ambrosia psilostachya, Helianthus maximiliani, Desmanthus velutinus, Stenaria nigricans, Hedeoma acinoides, Liatris punctata var. mucronata, Spiranthes cernua, and Krameria lanceolata.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: These areas are small inclusions in broader grassland and woodland areas. Often they are near streams but terrain is level to rolling. They occur on clay loam range site and Pleistocene alluvium. Apparently they occupy slight microtopographic depressions in clay loam soils that stay slightly moister.

Floristics: The vegetation is dominated by Muhlenbergia reverchonii. Other graminoid species include Eleocharis sp., Cyperus sp., Schizachyrium scoparium, Bouteloua curtipendula, Aristida purpurea, Sorghastrum nutans, Tridens albescens, and Bothriochloa laguroides. Forbs include Symphyotrichum ericoides (= Aster ericoides), Lythrum californicum, Desmanthus illinoensis, Bifora americana, Scutellaria drummondii, Monarda citriodora, Ambrosia psilostachya, Helianthus maximiliani, Desmanthus velutinus, Stenaria nigricans (= Hedyotis nigricans), Hedeoma acinoides, Liatris punctata var. mucronata (= Liatris mucronata), Spiranthes cernua, and Krameria lanceolata. At Fort Hood, this vegetation is dominated by Muhlenbergia reverchonii or codominated by Schizachyrium scoparium and Muhlenbergia reverchonii. The exotic grass Bothriochloa ischaemum is present in some occurrences. Three plots near the stream are characterized by Muhlenbergia reverchonii, Schizachyrium scoparium, Bouteloua curtipendula, Aristida purpurea, Sorghastrum nutans, and Bothriochloa laguroides. Forbs include Symphyotrichum ericoides, Helianthus maximiliani, Desmanthus velutinus, Stenaria nigricans, Liatris punctata var. mucronata, and Krameria lanceolata. More information is need on the composition and range of this association.
Dynamics: Increased moisture levels are important for maintaining this community.
Environmental Description: This association occurs as small inclusions in swales or low spots in broader grasslands or woodlands on level terrain. Often they are near streams (clay loam range site) and Pleistocene geology (alluvium). Apparently they occupy slight microtopographic depressions in clay loam soils that stay slightly moister. Adjacent vegetation may include grasslands dominated by little bluestem and Indiangrass or woodlands dominated by Juniperus ashei.
Geographic Range: This community occurs on the Edwards Plateau and Lampasas Cutplain of central Texas.
