Native of Mongolia, N. and W. China and the E. Himalaya. This is not one of the handsomest of cotoneasters, and is, perhaps, a poor form of C. lucidus (q.v.). There has been much confusion between the two, owing to C. lucidus also having been called C. acutifolius; but from that species the present one is distinguished by its dull green, not shining, more hairy leaves, and its woolly calyx and flower-stalks.
