122 TREES AND SHRUBS 



glauca (the Californian Blue Spruce) will be found 

 true to name when raised from seeds, while their 

 superiority afterwards over grafted plants is evident. 



CEDRUS, LARIX, AND PSEUDOLARIX. It should 

 always be remembered that these three are quite 

 distinct genera, and for purposes of propagation 

 should never be used in conjunction with each 

 other, the first being evergreen and the two latter 

 deciduous. The species of all three should be 

 raised from seed ; the varieties of Cedrus should 

 be grafted on that genus, the forms of Larix on the 

 Larch, though the geographical forms of the Common 

 Larch, such as var. rossica and var. sibirica, usually 

 come true from seed. Larix leptolepis (Japanese 

 Larch) is one of the most beautiful trees ever intro- 

 duced from Japan ; it is charming both in summer 

 and winter. Pseudolarix Kcempferi (Golden Larch), 

 the only representative of the genus, must be raised 

 from seed ; it is generally raised by grafting in 

 February under glass on stocks of the common 

 Larch. 



ABIES. In this genus some of the most handsome 

 Conifers are found, and also some of the most 

 difficult to grow. All the Abies should be propa- 

 gated by seeds, but if seed of the varieties cannot 

 be obtained then they must be grafted on the 

 parent species. 



PSEUDOTSUGA. This genus only contains one 

 species, viz., P. Douglasii (the Douglas Fir), which 

 is propagated readily by seed, the seedlings being 

 of rapid growth and soon form good plants. The
