Is this a grass or a grain

this is growing in the BC gulf islands on a slope that was disturbed and has repopulated with lots of invasives as well as local grasses. The stem has almost a reddish look in the top part and is very delicate looking. Almost reddish - purple from a distance. I have tried to show the head clearly in the photo

 

Looks like Bromopsis ramosa.

 

Thanks for replying. I have looked at the images and description on Hairy-brome | NatureSpot

and this particular plant does not have any hair on the stem. The number of spikelets on the head varies from 5 to 8 but a lot have 6

 

Compare against these? http://www.goert.ca/documents/B.rigidus+sterilis.pdf

 

Thanks. After looking at good images of both and reading the species information on
E-Flora BC Atlas Page

I believe it is Bromus sterilis.

Thanks

 

That's what I was thinking too, good to see we're in agreement!
