of the origin of M. arnoldiana is correct, it is the 

 of f spring of two hybrids of different parentage, and is 

 a good illustration of what can be obtained by crossing 

 and recrossing the crabapples. It is a low, broad, 

 bushy tree with long arching upper branches which are 

 raised well above the general head of the plant and 

 are wonderful objects when clothed from end to end 

 with flowers and the blue sky is seen between. The 

 flower buds, like those of M. floribunda are of deep rose 

 color and the petals , after the flowers open, gradually 

 turn from rose color to white. The flowers, however, 

 are as large as those of M. cerifera, or nearly twice as 

 large as those of M. /loribunda, and the red fruit is 

 intermediate in size between those of the parents."
