brome grass,common name for any plant of the genus Bromus, chiefly large, coarse grasses of a weedy nature; some, however, are useful as forage, and others are cultivated for decoration. Some of the better-known bromes are the smooth brome (B. inermis, sometimes called awnless, or Hungarian, brome), often cultivated for pasture or for holding banks; rescue grass (B. catharticus or B. unioloides), a forage in the Southern states; cheatgrass (B. tectorum, also known as downy, or drooping, brome), a Eurasian native that is a pest and fire hazard on North American rangeland and prairie; and rye brome (B. secalinus, also called chess or cheat), a Eurasian grass that is pest of North American grainfields, formerly believed by some to be degenerate wheat. Many species of brome grasses develop sharp-barbed fruits at maturity that are injurious to stock (whence the name ripgut grass for some); before maturity these are often used for forage. Brome grasses are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).
