Reference: EcoArt 2002
Description: This tallgrass alliance is known from Alfisols in the northeastern portion of the Blackland Prairie of Texas. The dominant species include ~Sporobolus silveanus, Tridens strictus, Paspalum floridanum, Carex meadii$, and ~Fimbristylis puberula$; other typical species (some in a lower stratum) include ~Dichanthelium oligosanthes, Dichanthelium linearifolium, Dichanthelium aciculare, Panicum virgatum, Paspalum floridanum, Coelorachis cylindrica, Aira elegans, Eragrostis hirsuta, Eragrostis capillaris, Neptunia lutea, Linum medium, Symphyotrichum ericoides (= Aster ericoides)$, and ~Symphyotrichum pratense (= Aster sericeus var. microphyllus)$. Areas which have been mowed or overgrazed may have ~Andropogon ternarius, Rudbeckia maxima, Marshallia caespitosa$, or scattered woody species such as ~Maclura pomifera$ or ~Juniperus virginiana var. virginiana$. One association occurs on loamy, low pH upland soils classified as Alfisols. This alliance is rare and has a very limited distribution. Remaining examples have been impacted by overgrazing and lack of prescribed burning. Much of the original acreage has been converted to row crops or tame pasture, or has succeeded to woodland. The exact species composition varies with changes in microtopography.
