the hypostyle covering about one third of the dorsal side.

Western Szech’uan: Min Valley, near Sung-pan Ting, alt. 2300- 
2600 m., September 1910 (No. 4014). 
This variety approaches Cotoneaster racemiflora, var. soongorica in the character 
of its pubescence, but the small, ovoid fruits easily distinguish it from this and all 
other forms of Cotoneaster racemiflora. It may possibly be a distinct species.
