, , SELECTIN'G STOCKS. 237 



Varieties of the evergreen species of the Cherry, such as 

 C. ilicifolia, G. Lauro-cerasus and the C. Lusitanica, 

 should, of course, be grafted on stocks of their own or 

 closely allied species. 



Cham^ctpaeis (Cypress). — See Coniferae. 



CniONANTHrs (White Fringe). — Almost any species 

 of the Ash {Fraxinus), makes a good stock for the 

 American White Fringe (C. Virginica) and the Chinese 

 species (C retusus). The European Ash {Jf. excelsior), 

 is, however, usually preferred to the American species as 

 a stock for the fringe trees. 



Conifers (Cone Bearing). — With but few exceptions, 

 the Conifers are evergreen trees or shrubs. The ever- 

 green kinds must necessarily be confined to stocks of the 

 same gi'oup and the deciduous to their own. As a rule, 

 in seeking stocks for the Conifers, the nearer we can keep 

 to the species from which the varieties under propagation 

 originated, the, better, although in a few instances some 

 closely allied species may have proved to be superior for 

 this purpose than the original. For the Abies or Firs, 

 the European Silver Fir {A. pectinata), has been most 

 extensively used as a stock for the different species and 

 varieties of the genus, mainly because it was most com- 

 mon and readily obtained. Any of the other larger grow- 

 ing species native of cool cUmates will, however, answer 

 equally well. 



With the Pines {Pinus), the species with two and three 

 leaves in a bundle should be employed for varieties of the 

 same, such as F. sylvestris, F. s. nana, F. MugJio 

 compacta, F. Fyrenaica, F. densiflora, etc. Tlje com- 

 mon Austrian Pine {F Austriaca), may be used as 

 a stock for our Western Pines (P. ponder osa, F. Coulter i 

 and P. Sdbiniana), as these all have heavy, coarse-grained 

 wood, and are closely allied to the Austrian Pine. But 

 a good, rapid and free growing three-leaved species is
