176 THE PRINCIPLES OF FLORICULTURE 



OTHER FORMS OF REPRODUCTION 



Reproduction by other forms, such as budding, layering, 

 and the like, is used to such a limited degree in ordinary 

 greenhouse work that it is considered unnecessary to 

 discuss it in detail. There are several books on plant 

 culture which treat specially of propagation. Among 

 them are " Principles of Plant Culture," by E. S. Goff; 

 Oliver's " Plant Culture," and the " Nursery-Book," by 

 L. H. Bailey. Students and readers are referred to them.
