Please check subsp. of !

Any keys?

It has closeness to Prunus cerasoides Buch.-Ham. ex D.Don, but for the flowers.
Can you the calyx?

Calyx looks somewhat different from Prunus cerasoides Buch.-Ham. ex D.Don

Kindly check Prunus triloba, Rosaceae

Does not have distribution in our area and also looks different as per POWO.
