Not certain, but that Dunstan is likely a hybrid species of American with Chinese chestnut for blight resistance.
The genetically pure American Chestnut tree was nearly eliminated by this blight. So backcrossed hybrids and genetically modified varieties of the American Chestnut are exciting, because there's a hope they could return to their former glory in the ecosystem.
This particular tree is a large specimen of genetically pure American Chestnut, growing in the east coast region as well, so a great find for conservation.
In all, hybrids may be great for individuals, but this movement intends to be more selective for restoration purposes.
I agree with you and know that the Dunstan is "debatable" to its origin. imho it's American, going by https://acf.org/wp-content/uploads/2016/09/leafcard.pdf. I know I have a chestnut tree. I know it has lots of teeth and no hair.
My point is more a point of having periodic postings about Chestnut trees. I think once every 5 years would be enough on the same exact subject. It has been a trend every year. OK so more people are just discovering the issue every year I guess.
