Spotting

Description:

Tree in my backyard. It is around 20 - 25 feet tall, is a tree not shrub. The "nuts" get to be around 1/2 - 1 inch around and stay green until they fall... the inside (surrounded by green flesh) is a little brown nut that is totally solid, no indentation or any markings. Nuts begin to grow in the spring and fall off late September.
