The Chinese Pear
The Oriental pears have not the characteristic shape of the European pear. The latter was presumably modified in shape through selection at a comparatively recent period. It is supposed that the original home of the pear was Central Asia, and that the fruit was carried into Europe in prehistoric times. The pear is characterized by having a fibrous or woody deposit in the skin, indicated by the dotted appearance of this Oriental specimen.
