From Jamaica Plain, Mass. Scions presented by the Arnold Arboretum. 

 Received January 2, 1917. 



This wild Chinese pear is not uncommon in western Hupeli at altitudes of 

 I 1,000 to 1,500 meters. It is easily recognizable by its comparatively small 

 | crenate leaves and small flowers. This pear maintains a vigorous and healthy 

 i appearance under the most trying conditions, and might prove to be a very 

 I desirable blight-resistant stock. The woolly aphis, which attacks other species 

 \ of pears, has not been known to touch this species. (Adapted from Compere,
