Ok, folks, here we go.  Can you guess this familiar, native tree based on the photographic clues below?

Here is a picture of the fruit/seed, which last on the tree until late winter.

Here is a picture of the classic, mottled bark of this tree.

And here is a leaf.

You know this!  Think about it, and post your guesses in the comment section below, and thanks for playing!
