Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, alt. 
2300-3000 m., June 1908 (No. 2179, type); west of Tachien-lu, alt. 
3300 m., October 1908 (No. 1270); Tachien-lu, thickets, alt. 2600— 
3000 m., June 1908 (No. 2178); around Tachien-lu, alt. 2600-3000 m., 
1903 (Veitch Exped., plants in Hort. Veitch under Nos. 1507, 1723). 
Allied to Cotoneaster acutifolia Turczaninow, which is readily distinguished by its 
generally ovate much less pubescent leaves and more densely pubescent calyx. 
Frora Cotoneaster moupinensis Franchet this new species is easily recognized by 
its smaller foliage, which hardly ever shows any tendency to become rugose, its 
smaller inflorescence and flowers, and by its globose fruit. 
It must be confessed, however, that there is a great similarity between all these 
black-fruited Cotoneasters from China. With Cotoneaster acutifolia Turezaninow 
at one end of the chain and Cotoneaster moupinensis Franchet at the other it is 
almost possible, with the material before us, to connect the whole series. The 
living plants look quite different, and since all the species and varieties named 
above are in cultivation, it may be possible later to determine their affinities more 
accurately. 
Nos. 1270 and 2178 differ from the type in their thicker, broader leaves. No. 
2178 has a more numerous-flowered corymb, broader sepals, showing some approach 
to Cotoneaster moupinensis Franchet.
