A species of wide range in Asia, from the Caucasus through Central Asia and W. Siberia to China; a variety (see below) is found in Spain. It was first discovered in Siberia, in the Altai Mountains, and introduced to Kew in 1837. This is one of the most elegant of cotoneasters. There is a specimen at Kew with a single well-formed trunk supporting a crown of pendulous or arching branches; the whole 10 to 12 ft high. When the branches are wreathed with abundant blossom in May and June, this tree makes a most charming picture. The same species was later found in China by Wilson and other collectors.
