of cultivation, and in May and June, when in full flower, is a 

 perfect picture, the white flowers nearly hiding the young 

 [eaves, which are beginning at that time to cover the branches. 

 It may either be propagated by layers, or by budding and 

 grafting on the common plum stock. 



P. siberica scarcely grows so large as th candicans ; thrives 

 well in almost any soil and situation, and makes a pretty orna- 

 ment when in flower. It may be increased both by layers and 

 budding, or grafting on a common plum stock. 



PYRUS. 



The Apple, the Pear, the Service, the Beam tree, and the 

 Mountain Ash, besides several less important plants, belong to 

 this genus. 



Pyrus coronaria. Sweet-scented Crab. This beautiful 

 Crab tree is a native of North America. It grows upwards of 

 twenty feet high. In May, when it flowers, a delightful fra- 

 grance is emitted, which in the evening perfumes the whole of 

 that part of the garden. It will grow in almost any low situa- 

 tion, and may be propagated by grafting on other crab stocks, 

 or by layers. 



P. floribunda. This forms a broad-spreading, but not very 

 lofty, bush, which in spring is thickly covered with blossoms, 

 and in autumn with purple berries. It grows freely in com-

 as coronaria. 



P. spuria. A small deciduous shrub, very hardy, and easy 

 of propagation. Grafted upon the common stock, or crab or 

 pear stocks, it grows very freely. 



P. angustifolia. This very pretty shrub rarely loses all its 

 leaves ; for, although not an evergreen, the leaves of the previ-

 high. It is propagated by grafting on the crab stock, and bv
