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.
