Cotoneaster acuminatus (commonly known as acuminate cotoneaster) is a species of flowering plant in the Rosaceae family that is native to the Himalayas. In forests it can be found at elevations of 1,300–3,000 metres (4,300–9,800 ft), while on hillsides it is found at 2,500–3,500 metres (8,200–11,500 ft).[1] The species has also been introduced to Oregon.
C. acuminatus is 2 to 4 metres (6 ft 7 in to 13 ft 1 in) in height. Its petioles and lanceolates, both of which are villous, are 3 to 5 millimetres (0.12 to 0.20 in) in length.
The species is found in Bhutan, Nepal, China (Sichuan, Xizang, Yunnan), and India (Sikkim).

Thanks, …, for enriching this fortnight

I am pleased to report that Jeanette Fryer has confirmed that this is Cotoneaster acuminatus Lindley.
Recorded from Nepal, Sikkim and Ladakh (this seems a surprising record).  Brandis stated that C.acuminatus often occurred as understorey in oak forests of Western Himalaya.
