Bromus secalinus · ruginė dirsė
en.wikipedia.org/wiki/Bromus_secalinus The 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 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.
