THE ORIGIN OF A VARIETY OF EUONYMUS 



On this green shrub, part of a branch has become variegated, due to some internal change 

 which has affected the pigment. But internal changes of this sort are apparently never 

 confined to a single character. Not only is the color of the leaves changed, but their shape 

 is likewise altered, and the difference in appearance extends to the_ stem. Changes of 

 this sort are rather common, and probably have not much importance in normal evolution, 

 but they are sometimes of much value to gardeners, many ornamental varieties of plants 

 having originated in the .same way that the silver-variegated Euonymus did. (Fig. 5.)
