Name: Panicum virgatum - Tripsacum dactyloides Herbaceous Alliance
Reference: Southeastern Ecology Working Gro...
Description: This alliance includes wet-mesic grasslands of the southeastern United States that are dominated by Panicum virgatum and/or Tripsacum dactyloides. The nominal species may occur with Andropogon gerardii, Carex microdonta, Fimbristylis puberula, Paspalum floridanum, Sorghastrum nutans, and Sporobolus compositus var. compositus. Important forbs may include Acacia angustissima var. hirta, Symphyotrichum ericoides (= Aster ericoides), Bifora americana, Hedyotis nigricans, Helianthus maximiliani, Ratibida columnifera (= Ratibida columnaris), Rudbeckia hirta, and Ruellia humilis. There are wetter and drier variants; the former occurs on poorly drained or subirrigated soils (Vertisols) and flat topography on the northeastern Blackland, Fayette, and Upper Coastal Prairies of eastern Texas, and may manifest as patches of sparse vegetation interspersed with dense stands. Similar communities may exist as small patches in Oklahoma and Kansas. Remnants of this vegetation in Kentucky are on poorly drained flats in the Big Barrens. There is a reported Panicum virgatum-dominated type in the Grand Prairie of Arkansas.
