two different types of sod?

Hey,
I ordered sod and I'm worried I've got two different types. I ordered Meyer z-52 zoysia, but a good half pallet is very different. Was looking for another opinion. I've put pictures to both for comparison.

I'm by no means a grass expert, but the bottom pictures, especially the last one, looks a good bit like St. Augustine grass. Check out that type of grass on the net and see if it looks like what you have as far as descriptions you will get.
