I did the research and found what this tree is. I just thought I'd put this on for others to enjoy. See who can ID it first. The tree is about 50' tall, growing on the east side of Houston, TX. The lady who live there says the tree drops about 8-10 of these a year mostly hitting their roof. The biggest she has seen weighed over 7 lbs. This one I have weighs 3 1/2 lbs. I got 85 seeds from it.
So take a shot. No prize for the first unless you want a couple of seeds.
