From what I understand, a wolf tree can be a tree that survives a fire when the surrounding trees are killed off. It can grow in all directions and reach higher than anything around it, as it has no competition. That also makes it susceptible to lightning strikes because it's the tallest thing in the area. They also tend to die from the inside out which makes them dangerous to leave up. I didn't find any reference to wolf trees throwing seeds, though.
If you Googled wolf tree, you would have seen the photos of them. I have been looking at the trees along Barton Creek since I found my notes. I've spotted one gnarly looking oak tree by the bridge that could be a wolf tree. The next time the tree trimmers are in our neighborhood, I'm going to ask the foreman about them. I bet there are some in Bastrop now after the fires a couple of years ago.
Saw The Shawshank Redemption, but too long ago to remember details.
