IPM1007, Revised November 2009
Winter annual grass
A winter annual grass similar to downy brome but leaves are less hairy and seedheads are more upright and robust. The leaves are rolled in the shoot and can be smooth or occasionally hairy on both surfaces. Leaves lack auricles and have a membranous ligule that is 1-1/2 to 2-1/2 mm long and is usually distinctly toothed or fringed with hairs near the top. Leaf blades are approximately 5 to 10 mm wide. Leaf sheaths are round and can also be smooth or slightly hairy on the lower portions. The seedhead is a drooping panicle but more upright than that of downy brome. The spikelets also have shorter awns than those of downy brome.
