I have an abundance of this grassy weed in my yard and am trying to figure out how to best remove it. It is very tough, I have sprayed Roundup Weed and Grass killer on it and it takes nearly 2 weeks to die off. I have tried to find it in weed website galleries, but I cannot seem to find this one anywhere. Any identification and advice on how to best get rid of it is most appreciated!

I seem to see three hard to kill plants in your first image. Wild violets,. Yellow Nutsedge, and Johnson grass. In the second photo the corn like plant is Johnson grass. The one with long narrow blades is Yellow Nutsedge, Its characteristic flower head is visible in your first photo. The old folks use to say you have three choices . Hog pasture, Chicken yard, or move away and leave it. Hogs and chickens will do a number on it as they will dig up the roots. Today it can be killed with herbicides, but it takes time and effort. no magic bullet.

Johnson Grass, that's the one, thank you! Thank You!

Yeah, I figured that it was going to be a nightmare to get rid of, it is very resistant to everything I've tried already.

Your yard is very wet. At least this section that you are showing.
I see nut sedge too and also Dichondra and dollar weed! All of these plants grow in wet, sandy areas in Florida.
When I lived there up until April of 2018, the wetter area within my lawn was just full of these plants. That ribbon like plant, the name escapes me, also loves very wet sites. Those wet sites are called swales or sloughs. The State of Florida frowns on homeowners doing anything in terms of fertilizing or weed killing during the rainy season! The rainy season typically runs from mid-May through September.
Because of all the tropical storms and thundershowers, those sloughs produce a lot of runoff and those chemicals wreck havoc with the Florida ecosystem and waterways. Fines can be rather costly!

I would be very careful in doing anything in these areas now until the rainy season is over.

Thanks for the warning. I do indeed live in northern Florida and it is very wet in this area. I have read that a good way to kill Johnson Grass is by mowing it low, then weighing down a tarp over the area. It kills everything else sure, but as you see this particular patch of yard is ~85% weeds. I bought the house a few years ago and have been trying to get the neglected yard back in shape for years, without much result (at least I've got the sand spurs under control).

The ribbon-like plant is basket grass, I believe.
