BUDDING AND GRAFTING. 135 



C paniculata. Cormis florida makes a good stock for all its 

 varieties. Parrotia Persica^ Hamamelis Japonica, aud others will 

 graft on the common witch hazel. All lindens can be grafted 

 on the American or European varieties. Vitis Labrusca and V. 

 oistivalis make good stocks for all hardy grapes. Euonymus 

 Europceus is a good stock for all the Euonymus family. Acer 

 X>latanoides does well as a stock for all the forms of maple 

 excepting the Japanese maples, which will grow only on Acer 

 palmatum or A. Japonicum. Robmia Pseudacacia is good stock 

 for all the species and varieties of Robinias. All Wistarias 

 grow well on the roots of W. Chinensis. Caragana arborescens 

 suits all the Caragana species and varieties, and also Halimo- 

 dendron argenteum, and possibly other Leguminosfe. Vibui-iium 

 opulus and V. dentatum make good stocks for all Viburnums; 

 Catalpa speciosa for the other Catalpas, and for Tecoma radicans. 

 Ulmus campestris is best for all the English elms, and U. Ameri- 

 cana for the American types. Quercus rubra is best for most of 

 the oaks, although I believe the red oaks would do better on 

 Q. rubra var. tinctoria. All the hornbeams and hop horn- 

 beams, work more readily on Garpinus Betulus than they do on 

 our own species. The European white birch (Betula alba) is the 

 best for the general run of birches, while Alnus incana does well 

 for the alders. Corylus A'jelkma, the English hazel, is a good 

 stock for all the species and varieties. The common horse- 

 chestnut (^sculus Hippocastanum) is good for all its varieties, 

 as well as the red and the yellow buckeye, uE. rubra aud u3^. 

 Jlava. The fine varieties of hickory will graft on Carya porcina, 

 and C. alba, but I believe they will graft more easily on C 

 amara (the bitter-nut) ; it is of much more rapid growth than 

 the other hickories, and while young the tissues are softer. The 

 common chestnut is a good stock for all the Japanese, English, and 

 Spanish chestnuts. Cerasus sylvestris, (the Mazzard cherry), is 

 as good a stock as can be found for standard cherry trees, and C. 

 Mahaleb will serve well for dwarfs. Prunus demissa will graft on 

 P. Virginiana but not on P. serotina. The American and European 

 beeches make equally good stocks for all varieties of that genus. 

 Gleditschia triacanthos is a good stock for the weeping, and also 

 for all Japanese varieties. Pterostyrax hispidum makes a hardier 

 plant if grafted on the Halesia, than it does on its own roots. 

 Magnolia tripetala, or umbrella tree, and M. acuminata (the
