I've had this in my yard in Arizona for awhile but it has no tags and i can't figure out what it is. Is it a citrus tree? If so, what kind? It has thorns and very small leaves. Thanks!

It does look very much like a citrus tree. Hopefully one of GardenStews excellent American experts will come along and tell you for sure as they will have a much better idea of what grows in Arizona than me in rural Essex.
I've not seen citrus with green branches like that. It almost reminds me of palo verde except the leaves are too big. Where did you get it? Can they help you? dooley
