There are many sp of Cotoneaster.
Quote wiki...."Depending on the species definition used, between 70 and 300 different species of Cotoneaster are described, with many apomictic microspecies treated as species by some authors, but only as varieties by other"
I would not like to try to say which one it might be.
However it is one with long stalks, berries which hang in clumps.
.....such as Cotoneaster frigidus. (I am not saying the one above is C. frigidus!)

Thus it rules our C. franchetii./C lactaeus and C. simonsii.
