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 recrosslng 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. floribunda, and the red fruit is 
intermediate in size between. those of the parents."
