Setaria palmifolia
Setaria palmifolia is primarily an Asiatic species. It is a common species in Jamaica, and has been reported from scattered locations around the southern coast of the United States. In the Flora region it is occasionally cultivated as an ornamental for the conspicuous, plicate leaves and large panicles. In Southeast Asia the grains are eaten as a substitute for rice and the tender, thickened shoots as a vegetable.
