Distribution: also Szechuan, Yunnan; Himalayas. 



The extension of the range of an Himalayan species as far northeast 

 as Shansi is unusual, but the leaves of the specimen agree well with those 

 of P. pashia and the solitary fruit is small, 3-celled and has a persistent 

 calyx, as is sometimes the case in P. pashia; the specimens from Kansu 

 are very similar and have partly persistent and partly deciduous calyx. 



The account given above of the pears of northern China is necessarily 

 incomplete and unsatisfactory, as the material at my disposition is very 

 fragmentary, in many cases consisting only of sterile branches. We 

 cannot hope to arrive at a satisfactory understanding and classification 

 of the Chinese pears, spontaneous and cultivated, unless we have ample 

 flowering and fruiting material from the same locality or still better 

 from the same tree with notes on the color and nature of the fruit and 

 reliable statements whether the tree is cultivated or spontaneous or 

 possibly escaped from cultivation.
