RANGE OF THE VARIATIONS. 



At this point the data already presented may be summarized and anal- 

 yzed in reference to the range or extent of the variations as a whole. 



There have already been described 15 different color patterns that 

 arose by bud variation, 1 very decided color pattern that arose solely 

 as a fluctuating variation, and the laciniate type of leaf. Several of 

 the principal types arose also by fluctuating variations. In respect to 

 the relative amounts of green and yellow there are the two extremes: 

 (a) almost pure development of yellow (fig. 1), and (b) pure green 

 (figs. 5 and 9), with almost every possible gradation between. Of the 

 epidermal red there are the extremes solid red and no red with the 

 intermediate red-blotched type (including wide variations), and the type 

 solid red upper center as another intermediate. In respect to the relative 

 positions of the green and yellow there are the extremes: (a) green center 

 w^ith yellow border (fig. 2) and (6) yellow center with green border (fig. 6) . 

 Between these the irregular patterns present numerous intermediates.

Diagram 3 gives a graphic representation of the extent of variations 

 in each pattern and shows the derivation of types and the appearance 

 of the same types of pattern as variations from quite different patterns.
