Grass refers to various families of plants. The three major families of grasslike plants are true grasses (Poaceae), sedges (Cyperaceae), and rushes (Juncaceae). Lawns and pasturelands are typically composed of true grasses, five of which cover 46% of the world's arable land: rice, wheat, maize, barley, and sugar cane.
