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 ita 

 generally ovate much less pubescent leaves and more densely pubescent calyx. 

 From Cotoneaster moupinensis Franchet this new species is easily recognized by 

 its smaller foliage, which hardly ever shows any tendency to become rugose, ita 

 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 Turczaninow 

 at one end of the chain and Cotoneaster moupinensis Franchet at the other it ia 

 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 afl5nities 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.
