Often cultivated for its fruit in the neighborhood of Peking and in Korea. 

 This plant does not appear to be known in a wild state. It is aborescent in 

 habit, while the type is usually shrubby ; the leaves are larger and the much larger 

 fruit is distinctly obovate, not short-oblong as in the type. With our present 

 knowledge of the Chinese Crataegi it seems best, however, to consider this a vigor- 

 ous large-fruited form developed by selection and long cultivation.
