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.
