Physiognomy and Structure: No Data Available

Floristics: This association includes herbaceous vegetation heavily dominated by Sorghum halepense which is a tall-growing, robust and weedy non-native grass. Other non-native grasses, such as Phleum pratense, Schedonorus arundinaceus (= Lolium arundinaceum), Setaria parviflora, and Digitaria ischaemum may be present at lower cover values. Andropogon spp., Cyperus spp., and Carex cherokeensis, are other (native) graminoids which may be present. Forbs include Melothria pendula, Commelina communis, Cocculus carolinus, Erechtites hieraciifolius, Lactuca floridana, Rumex sp., Diodia virginiana, Trifolium pratense, Solanum carolinense, and Chamaesyce maculata (= Euphorbia maculata).

Dynamics:  This association occurs in old fields and along the edges of roads and fields. Sorghum halepense is kept out of agricultural fields with herbicides but can colonize after cultivation ceases. Sorghum halepense is considered to be one of the ten worst invasive weeds in the world (Holm et al. 1977).
