Solved Weed that smells of lemon

This stubborn weeds keeps coming back, it’s smells of lemon when ripped, any ideas what it is?

 

That's pineapple weed

 

That’s the stuff, thank you very much

 

Never heard it called pineapple weed, remember this from when I was a kid, rarely see it these days.
It seems to have died out round here.

 

Not sure what its real name is. We have it down the bridle path that I walk the dogs. I get the odd bit in our lawns. I can send some over if you want a bit
