The height ranges from 40 to 120 cm (47 in). The panicle is 7–20 cm, usually nodding and often spreading,[4] but erect as first.[5] The leaf-sheaths are hairy, the upper are usually hairless.[5] B. commutatus is stouter than B. racemosus, the smooth brome, with a flower-head not drooping to one side and a broader elongated branched flower head.[6]

Africa, W. Asia. It has been introduced into North America and in the United States is known as 'Hairy Chess'. The flowering period is from May to July.[3]
