*irndeveloped flowers of the largest size and most highly difl'erentiated — 

 i.e., buds of almost normal size which never open and wither early. 



In connection with an investigation of the nature of thes(3 

 undeveloped flowers we have been concerned with a study of their 

 occurrence both in the field and in garden cultures. As a result we 

 are prepared to make the following general statement : A rootstock 

 bearing a normally flowering shoot in a given year may the following 

 year produce a shoot bearing an undeveloped flower of larger or 

 smaller size, while the reverse sequence of events rarely takes place. 

 This point is emphasized in table 2, in which a cross indicates the 

 production by a rootstock of a shoot or shoots with normal flowers 

 and a dash indicates the presence of an undeveloped flower. A large 

 percentage of the more than 150 rootstocks grown in our garden cul- 

 tures bore normally flowering shoots when collected, or were known
