Betula Youngii.
Whilst between cameras I, accidentally, obliterated almost all I took "Today", leaving precious little, valid, to choose from.
I doubt young Youngii will replace Prunus serrula; behold its trunk, but it's hard by and I can no longer pick the boss's brains on citing. It's NOT a fast grower, so far as I can see from two nearby - I wonder?

Onward and upward.
