My friend has a fruit tree on the property she recently moved to that has a fruit tree on it, but we don't know what it is. Can anyone here identify it for us? Here's a couple of pics of it, as well as a pic of a piece of fruit from it cut in half.

Poncirus trifoliata...?

I don't think so. The skin/peel would be fuzzy, kind of like a peach, but the skin on this is more like a lime.

Lemon, maybe Meyers Lemon?

Where's it located. If it's Alaska I'm probably wrong.

Not any citrus I've ever seen. First photo I would have sworn was lime...second photo no idea!
This site is international, so it would help to know where in the world the subject is growing when asking for an id.

It's in San Diego, CA.

We first thought they were limes, but it doesn't smell like any kind of citrus. The neighbors have lemons and they're all yellow, so it would seem odd that these would would still be green if they were lemons. I would imagine they would ripen around the same time, but I don't know much about growing fruit.

I'm in north San Diego. I wonder what it is? The inside looks very dry. Have you tasted it?

I looks like a lime but not developed right, are all fruit like this?

From the tree leaves and thorns it is a citrus
most likely a lime
the problem you are seeing is most likely from too much nitrogen (causes super thick rind)
This looks like s very lush(leafy) tree from your picture . The dense foliage also caused too much nitrogen .

Makes for a nice looking tree lousy fruit.

Most likely explanation

I think that's it. It sure looks like it. Thanks a bunch!

Great detective work SoCal!

Hmmm, I'm blind. I don't see a thick skin on it. Whatever it is, to me it looks like it's not ripe yet.

I'll use a watermelon for example. The skin is green on the outside and lighter green turning to almost white in the inside, then there's the red part which is the meat of it. The pic of the fruit that I posted looks like the inside/lighter part has grown all the way to the center, and there no real meat to it. That's how it looks to me, anyway.

Ok. It just looks unripe to me...whatever it is...I can see where that could be a (very) thick skin. I hope ya'll figure it out and what to do to get it edible. Could it be some type of ornamental? Osage orange (your bush isn't osage orange) produces a "fruit" of sorts...big "oranges" but they're not fit to eat and really just make a mess (great firewood and fenceposts, though! ).

Keep us posted.

We're going to take a piece of the fruit to a nursery and see what they suggest we do. I post here what the outcome is. Thanks for the help. Cheers!

Key Lime from Picture This application for your cell phone. The key is the pale yellow developed in the center of the cut fruit, the tree thorns and leaf form.
