 •Tune and July and maturing its fruit in December, when it is very ornamental from the contrast

A o-enus of about 40 species, inhabiting the temperate regions of the northern hemisphere. As 

 generally received it includes the Pear, Apple, Crab-apple, Quince, Choke-berry, Service Tree, 

 &c., most of which have been at times recognized as distinct genera, and are so ranked by De- 

 caisne in his recent revision of the Pomacccc. P. communis, Linn., the common Pear, indige- 

 nous to Europe and Asia, is considered by him as including all the thousands of vaneties of that 

 fruit. It is occasionally found escaped from cultivation in neglected places, but rarely fruiting. 

 The Apple, P. Mains, Linn. (Malus covimunis, Lam.), also a native of Europe and Asia, is 

 likewise sometimes found growing without cultivation and bearing a small sour fruit.
