Numerous species were once considered members of Setaria but have since been reassigned to the genera Brachiaria, Dissochondrus, Echinochloa, Holcolemma, Ixophorus, Oplismenus, Panicum, Pennisetum, Pseudoraphis, Setariopsis, and Urochloa.
Several species have been domesticated and used as staple crops throughout history: foxtail millet ( S. italica), korali ( Setaria pumila) in India, and, before the full domestication of maize, Setaria macrostachya in Mexico.
Other species that have been cultivated as crops include S. palmifolia (highland pitpit) of Papua New Guinea, where it is cultivated as a green vegetable; S. parviflora (knot-root foxtail), historically cultivated in Mesoamerica; and S. sphacelata (African bristle grass) of Sudan, a "lost millet" of Nubia.
