The pear (Pyrus communis) is a deciduous, usually thorny tree of the family Rosaceae, genusPyrus. It is native to Europe and Asia. The leaves are narrowly lance-shaped to broadly oval. The flowers are white or pinkish, in flat-topped clusters, appearing before or with the leaves. The fruit has a characteristic gritty texture caused by the presence of stone-cells in the flesh of the fruit. Research Pear
