good morning pals, I’ve got a meeting in a few minutes and I am not yet awake 
Discussion
That looks like tansy. Noxious weed and the oil if you touch it can also cause skin rash. It also used to be used in a tea to get rid of tapeworm.
I have friends who are removing it from their property by hand so their horses and cows don’t eat it.
I think it may be Hymenolepis crithmifolia but I can definitely see how this angle looks more like tansy!
