Fig. 2018. Pyrus is a polymorphous genus, comprising some 30 to 50 species in the northern hemi- sphere. Trees or shrubs, with alternate leaves which are simple in the common species but compound in P. heterophyUa and rarely in some of the apple tribe. The species are cultivated for their edible fruits and for ornament. Apples and Pears are the leading species. The species are mostly small trees, bearing clusters of showy white or blush flowers with the leaves or in advance of tliem. They are natives of the northern hemisphere, mostly of cool temperate parts, and the greater part of them are hardy in the northern states. They are of easy culture. The pear-like species may be worked on Pear stocks, and the apple-iike species on Apple stocks. The fruit of Pyrus is of the kind known to botanists as a pome. The morphology of the pome is still a sub- ject
