Chili: near Peking, E. Bretschneider (ex Rehder, 1. c.). 



This species is known to me only from cultivated plants raised from 

 seed sent to the Arnold Arboretum in 1882 by Dr. E. Bretschneider. It 

 is most nearly related to P. betulaefolia , but easily distinguished by its 

 larger usually 3-4-celled fruit, the larger more closely serrate glabrous 

 leaves and the less tomentose branchlets and inflorescence. Besides the 

 typical form with pear-shaped fruit, there is a form with globose fruit 

 distinguished as f. globosa Rehd. (1. c).
