a fragrance like that of ripe apples. These newer 

 hybrids — Avalanche, Boule d' Argent, Gerbe de Neige, 

 Manieau d'Hermine, Mont Blanc, and Lemoinei — are 

 all worth a place either in the open ground or for 

 flowering in pots. 



Prunus. — Several classes that were at one time 

 considered as separate genera are now included in 

 the genus Prunus, which was formerly limited to the 

 Plum family. Now the Cherries, Almonds, and 

 Peaches are only sections of the genus Prunus, as 

 explained elsewhere in this book, but as they are 

 better known under their respective names it will be 

 wiser to refer to them thus. The Cherries {Cerasus) 

 have been added to considerably of recent years, 

 several varieties having come from Japan, mostly of 

 P. {Cerasus) pseudo-cerasus. These, which include 

 such varieties as Sieboldi, Watereri, and J. H. Veitch, 

 all flower freely when quite small, an important point 

 when considering plants needed for flowering under 

 glass. Where larger plants are required the double 

 form of the Wild Cherry {P. Avium) is very beautiful. 

 The Almonds (Amygdalus) flower early naturally, 

 and under glass, of course, earlier still ; the variety 

 purpurea is one of the best, while a distinct species, 

 A. davidiana and its variety alba, are also suitable for 

 growing under glass. The Peaches {Persicd) form a 

 delightful group, all available for flowering under 

 glass ; indeed, they respond readily to gentle forcing, 

 hence may be had in bloom by March. There are 

 several varieties, the flowers ranging in colour from 

 white, through pink, to crimson, and double as well
