Also known as awnless brome. Perennial, stoloniferous grass weed, which is found chiefly on dry sites and can grow as tall as 150 cm. Invades fields chiefly from the edges of roadways and ditches.
Leaves and leaf sheaths are normally smooth and hair free although sometimes hairs might be present particularly by the leaf sheath. The erect panicle is relatively large (Picture 2); the glumes are awnless (Picture 2), with or without bristles at the apex. Propagates by seeds and rhizomes.
