in another connection, in which the almond was 

 combined with the purple-leafed peach. 



It has already been recorded that the first- 

 generation hybrids of this cross bore green leaves 

 exclusively, but that purple leaves appeared in a 

 certain proportion of the hybrids of the second 

 and subsequent generations. 



In this cross, the purple-leafed peach was used 

 invariably as the pistillate parent. There is 

 every reason to suppose, however, that the 

 results would have been the same had the cross 

 been made the other way. 



Among the second-generation seedlings were 

 not only some with red leaves, but others that 

 showed a combination of colors varying from the 

 pure green almond leaves through different 

 shades to the crimson leaf of the peach. 



There was thus exhibited a pronounced tend- 

 ency to segregation of colors in certain cases, 

 and a combination of the colors in others. 



Selection being made among the trees with the 

 purple leaves, this characteristic, as might have 

 been expected, reproduced itself, and a race 

 of purple-leafed peach-almonds, was developed. 

 The fruit of this hybrid is purple-fleshed, and as 

 to its general characteristics it is a fair com- 

 promise between the peach and the almond, not 

 unlike the hybrid form already described.
