Hi again Dan,
I tried opening the research links under your post but they may have expired. Wondering if you could send me these via email?
The tree that I recently discovered near my property has all the characteristics of Adara including thorns on its mature scaffolds. This tree is at least 20 years old as I have watched it grow for years not knowing where it came from. If somehow I can verify it’s genus I would be willing to provide scions to others, but for now I am merely wanting to positively ID it.
