Bob,
I have a tree I can't find on the Internet It may be some kind of Mountain Ash, but it is not the one with berries on it. It has perfectly round fruit, yellow with red blush, bigger than golf balls. The fruit appears evenly distributed all over the tree. The leaves resemble a locust. Some locusts have red or yellow beans, so I thought it might b some kind of locust. I haven't got a clue.
I was going to call an expert to look at it last year, but next day. all fruit was gone and I couldn't find leaves on the ground. Right now, the leaves are even gone -- looks like something ate the leaves too I did not see fruit this year either. I have to get binoculars to see it...it's about 40 feet tall, very skinny tree on the edge of forest. Kentucky6
