Some late-fiowered Crabapples. The cool weather of late April and 
early May has favored the flowers of Crabapples, and although the 
petals have already fallen from the trees of Malus robusta, M. sylves- 
tris and some of the forms of M. haccata, many of the earlier species 
are still in good condition and others are fast opening their flowers. A 
few of the late-flowering species and hybrids which deserve the atten- 
tion of garden-makers and the lovers of handsome plants are: 
Malus spectabilis, a tree which has been long cultivated in Chinese 
gardens, although it is still unknown as a wild plant. This tree, which 
is possibly a hybrid, was first sent to England from Canton in 1780 
and probably was brought to the United States early in the nineteenth 
century. It is one of the largest of the Asiatic Crabs here, growing 
to the height of from twenty-five to thirty feet and forming a wide, 
vase-shaped crown of numerous spreading and ascending branches and 
short branchlets. The flowers are pale pink, semidouble and very frag- 
rant. The abundant fruits are pale yellow, nearly globose and an inch 
in diameter. This is a hardy and long-lived tree, as in the neighbor- 
hood of Boston are plants which are probably seventy-five or eighty 
years old. 
Malus Sargentii is a Japanese shrub only a few feet high, and much 
broader than it is tall, with wide-spreading prostrate branches. The 
flowers are in crowded clusters, saucer- shaped and pure white, and are 
followed by abundant wine-colored fruits which are covered with a 
slight bloom, and, unless eaten by birds, do not disappear until the
