Mosaic Variation 



Occasionally a seedling shows a mottled leaf like this. 



Such a seedling, although otherwise promising, is rejected. In 



this case vigor of growth in the tree is indicated by the size of the 



leaf and wood, but a leaf of uniform dark green color is to 



be preferred. This is interesting, however, as showing a 



peculiar segregation of color factors, one of the 



ancestors having been a purple-leaved plum.
