Synonyms (former Scientific Names):
Bromus commutatus var. apricorum
Bald brome is an upright-growing grass that can grow to 3 feet tall.
Leaves are 3-6 mm wide and are pubescent on both sides. The culms of bald brome are without hairs but the leaf sheath is hairy with the hairs growing upwards. The ligule is membranous and can grow up to 2mm.
Bald brome is recognizable by the pubescence on the leaf and hairs on the sheath growing backwards. The drooping panicle at maturity is another character that will help distinguish bald brome.
Flower Seed Head
The seed head of bald brome is a panicle that is 4-8 inches long. The panicle is upright at first but begins to droop once it is mature.
The fruit of bald brome is a caryopsis, or dry grain. The spikelets have 5-10 seeds each.
Bald brome is mainly a weed of disturbed areas and pastures.
