Panicum, a very polymorphic genus, and one of the largest in the order, is widely spread in all warm countries; together with species of Paspalum they form good forage grasses in the South American savannas and campos.
Nachani (Eleusine coracana) and kodra (Paspalum scrobiculatum), inferior grains grown on the hill-sides, furnish food to the Kolis, Bhils, Waralis, and other aboriginal tribes.
