An Asiatic Rowan cultivated in parks and gardens as an ornamental tree.
First of all, there seems to be confusion over the scientific name; it is variously spelled Sorbus khumbuensis and Sorbus khumbiensis, with the former winning out by 10:1 in a Google search, but that does not mean that the former is correct; a lot of copying goes occurs on the internet, which is particularly so with the description of this tree (every site uses exactly the same sentences! Your author concludes that it is all copied automatically by moronic computers that cannot even re-word a sentence!). It is possible one spelling is a translation into another language (but which spelling?).
This Rowan Tree has no common name. The leaves are pinnate, with about It has small, oval shaped leaflets which in autumn turn a deep maroon. The berries are at first pink and appear on the tree whilst the leaves are still present, but later turn pure white without any tint of pink. However, un-like most Rowan Trees, the leaves fall off early leaving just the white berries on the tree.
Your Author is now wondering how long it will be before my own and much longer description is copied on the internet into all the other sites.
