Chestnut ID Help

[Hydestone]

Hi All:

I have what I think is a Japanese Chestnut, but am not positive. The majoring of the nut pods have 3 nuts, but most are not full size. They sort of seem shriveled up. But every dozen or so, I'll get a very large chestnut. 

Any ideas?

Safe to eat the shriveled up smaller nuts?

I'm curious if someone can ID your tree. I'm waiting to hear the verdict on the feds deciding if they will approve the genetically modified chestnut trees. I would like to plant some.

Japanese or Chinese Chestnut.  Hard to really tell.

I would say Chinese. the small under developed nuts are from poor pollination. It takes 2 to tango, another chestnut within a few hundred yards to fertilize the momma tree.

I have a chestnut on my property that looks very similar, nuts are the same, too. I always assumed it was a hybrid. The researching I did online suggested 3-nuts = hybrid. Never did try eating them, squirrels get there first!
There's a plot of them nearby, looks like someone planted an acre or two about 50 years ago (based on their size), which jives w/ the die-off and re-planting efforts stateside. After the blight some folks made efforts to re-introduce the hybrid species. The one I have was clearly planted as an ornamental, but I have not seen any others nearby. I _do_ have beehives, and they do visit that tree when it is in bloom, so... had me wondering about the poor-pollination comment by @pesaventoc , could be my problem as there is no known donor nearby.
