Grass ID

These are in SE Oklahoma, taken last weekend.

This is found in low lying areas of a flat pasture where water stands. Leaves are stiff and coarse.

I thought all that green stuff was ryegrass. However, there are two types of seedheads.

The middle one could be ryegrass. I was thinking it may be Intermediate Wheatgrass but that grows too far north where you are.

The last one could be bromegrass...not sure about the first...

#2 definitely ryegrass
#3 looks like cheatgrass to me; brome is a possibility
#1 No idea

Thanks for the tips. With those, I did some specific image searching and it does look like #2 is the ryegrass (Lolium perenne) and #3 is rescue brome (Bromus catharticus).

I will wait for some thoughts for #1.

You're dead on with #3. Rescue thrived this year here in North Texas. Those seed heads are everywhere right now.

I was doing a little search myself last night and thought it might be something similar to Rescue Brome. Wasn't sure though, I didn't want to say anything in case I was completely off.

The other one (#1) I'm thinking could be some species of Wild Rye, especially since the leaves are coarse and rigid. Wild Rye is a type of grass great for stockpile grazing, particular this far up north. And since it's growing in a moist area (they do require moisture or irrigation to grow, from what I read), well then that's my hunch that that's what it is. Canadian Wild Rye appears to grow around that area, but the awns on that picture are much too short to be that species.

The other option is that this could be Switchgrass. The seed head above looks like it's either just going in or out of the point of flowering, and hasn't quite split apart yet.
