Bromus secalinus

Bromus secalinus is a species of bromegrass known as rye brome. The specific epithet secalinus is Latin, meaning "rye-like". The fruits are hard, rounded glumes that appear superficially similar to the rye grain, which gives the brome its common and scientific name. The grass has a diploid number of 28.

The grass is native to Eurasia but is well known in many other parts of the world where it has been introduced. It is a noxious weed throughout much of North America.
