480 seed pods, while but eight produced more than 450. (See table 
No. 7.) 
The terms ‘‘mutation” and striking variation have been used in 
describing the new form. That it will breed true to type and thus 
answer the requirements of a ‘‘mutation” has not been proved, hence 
the term striking variation is to be preferred. Young seedlings from 
this type, however, growing in the green house with normal seedlings 
do show a consistant difference. 
III. Bud Variation. 
It is not the purpose of this chapter to give a full review of 
the subject of bud variation. Without going into the different theo- 
ries as to the cause of these variations, or giving a catalogue of the 
important ones listed in literature, we may discuss them as real facts 
in existence. Webber?) has pointed out the possible analogy between 
bud variation and seedling variation as follows: ‚From our present 
knowledge of the cytology of heredity we would assume that heredi- 
tary changes such as those manifested by bud variation as well as 
seedling variations are due to rearrangements of the hereditary units 
or anlagen which occur during cell division. In the case of seedling 
variation we assume that this rearrangement takes place primarily 
during the progress of the reduction division that preceeds the for- 
mation of the sexual cells. So far as microscopic investigations go 
we have no evidence that would strengthen the idea of such a redis- 
tribution of characters ever taking place in the somatic cells. However, 
we have the strongest of all possible proofs that it does occur in the 
fact that in bud variation we get segregation of character analogous 
to the segregation in seedlings. In hybrids the characters very fre- 
quently segregate in the somatic cells giving branches resembling the 
pure parental characters which reproduce these characters through 
the seed. Cytological evidence against the possibility or probability of 
such an occurence is of no value in the face of its actual occurance“. 
East?) gives practically the same thought in this quotation: 
“The investigations reported in the foregoing pages suggest very for- 
cibly that the behavior of variations reproduced by budding is in
