not rye grass

Lolium perenne has (usually) awnless, sessile, spikelets, whilst this has awned, stalked, spikelets. I think that it may be Bromus, but it is not the common Bromus hordeaceus.

Not Rye Grass

Thanks all for helping me to identify this grass. Can you please, if you have time, tell me how it differs from Bromus Hordeaceus? I've had a look at other pictures/descriptions and they look v similar. I don't have sufficient knowledge/experience to see the difference myself. Thanks again.

My grounds for saying that it isn't Bromus hordeaceus ...

... are that the inflorescences are too lax, that is the spikelets aren't clustered enough. Beyond that I'm in the same boat as you - the different Bromus species all look very similar. (And I've never knowingly seen any Bromus - as opposed to Anisantha, Bromopsis and Ceratochloa - species other than Bromus hordeaceus.)

You may well also have a different habitat - in my experience Bromus hordeaceus is mostly a grass of hedgerow margins.
