Need help identifying tree

dealSeptember 22, 2007

I've had all kinds of suggestions about what kind of tree this is, but I'm not sure any have been correct. The tree is growing in a shady spot in English Ivy behind my garage.

Thanks.

Should be a Black Walnut (Juglans nigra)

Thanks treeguy. Juglans nigra was one of the things I had considered, except that branches don't seem to have a dark pith and I've never seen fruit on the tree. Do all Black Walnuts fruit?

You might not see a pith perhaps because the branch is young new growth. Yes all Black Walnuts fruit once they reach the right age. Open-grown trees in full sun such as out in a feild may produce a few walnut when only 4 to 6 years old, more commonly 8 or older.
Most Black Walnuts if grown in part to full sun can make a few as young as 12 years old but Black Walnuts produce the largest crop of walnuts when they reach 20 to 30 years old or older.

There is a chance it could be a Butternut (Juglans cinerea) but this tree is more rare in GA. If you live in extreme northern GA there's a possibility it could be this. If you don't live in extreme northern GA then it should defiantly be a Black Walnut.

Looks like a pecan leaf to me (carya illinoinenis).

I was thinking of a pecan also but I put it out earlier because that bark does not look like a pecan (more like a Walnut). But after looking at the twigs they look a little thin to be a Black Walnut so there's a high chance of it being a Pecan (Carya illinoinensis) also the leaves look more similar to Pecan than Walnut.

Looks more like Pecan to me too. To confirm, take a twig, and slice it lengthways up the middle. Chambered pith = Juglans, solid pith = Carya.

I don't know what it is (quirky not toogood with those 7+ leaflet trees) but I can say with certainty it's not a b.w.

I have pecan trees everywhere here, and the bark varies from tree to tree. Some are very shaggy, and others much less so, especially if they're younger. You'll find pecan trees in the stangest of places because squirrels bury the nuts wherever they can find (just like walnuts).

There's also the remote chance it could be pecan X bitternut hybrid, but I'm sticking with straight pecan.

Thanks for all the feedback. I sliced another twig, and here's what it looks like.

The pith is actually a little smoother than it looks in the picture. The knife action disturbs it and gives it the more grainy look.

So, based on other pictures I've seen, I would say that this isn't a chambered pith?

I'll say it's defiantly be a Pecan (Carya illinoinensis) after looking over everything more carefully. Pecan trees are monoecious meaning they have male and female flowers on the same tree. Pecans ripen in September and October and are dispersed from September through December on Pecan trees. The minimum seed-bearing age is 2 to 4 years in some cultivars but more commonly the age for Pecan production starts when the
trees are about 20 years old.

The chambering of the pith doesn't develop in Juglans spp. until the second year, so make sure you're not slicing this year's wood. I agree with those who say the leaf reminds more of pecan. Black walnut leaflet counts usually average over 15 with the terminal being less developed than shown here, or else absent.

Yes, like cacau said new green or first year growth won't have the chambered pith in the Black Walnuts.
It still looks like Pecan to me.
Here is a comparison of Pecan and Back Walnut from our trees:

Pecan. As cacau noted, J.nigra won't have a terminal leaflet.

"As cacau noted, J.nigra won't have a terminal leaflet"

It can do - it varies from absent, to present but small, to present and as large as the other leaflets. I've seen the full range of variation on one branch of a single tree, too.
