From Wikipedia, the free encyclopedia.
The Poales is an order of plants in the Class Liliopsida (monocots) of the flowering plants. Included in the order is the Family Poaceae (grasses) and their allies. This group basically corresponds to the Order Restionales in Cronquist's (1981) classification, except that he placed the grasses in the Order Cyperales. Since then it has generally been agreed that the Poaceae belong here, however, and in fact a few authors have removed the Restionaceae instead.
Otherwise the composition of the order has been fairly stable. By far, the most economically important family is the Poaceae — the grass or corn family, which includes barley, maize, millet, rice, and wheat.
