some in the autamn. The typical form is a low shrub broader than 
high with arching stems, and there is an arborescent form of excellent 
habit. This Crab produces great quantities of fruit which is not larger 
than a small pea and is bright red on some individuals and yellow 
on others. It has the merit of flowering later than the other Asiatic 
Crabapples. The variety calocarpa of M, Sieboldiana has larger 
flowers and fruit, and is a large arborescent shrub. As a flowering 
plant and when its bright red lustrous fruit is ripe it is one of the 
handsomest Crabapples. To Dr. William S. Bigelow of Boston, who 
sent the seeds to the Arboretum from Japan, western gardens owe 
this beautiful plant which is not known in a wild state. The small 
globose fruit of M. baccata, a common tree in northeastern Asia, 
varies considerably in size and in its shades of red, but all the forms 
are shapely trees handsome in spring and autumn. A Korean variety, 
var. Jackii, still rare in gardens, has perhaps the most brilliant fruit 
of any of the forms of M. baccata. A northern form, var. mandshurica, 
has larger fruit, and the flowers are more fragrant than those of any 
other Asiatic Crabapple. Attention may be called again to the value 
of Malus Sargentii as an autumn and winter plant. This is a shrub 
from northern Japon which grows only a few feet high but spreads 
by semiprostrate stems to a wide diameter. The scarlet fruit, which 
is produced in great quantities, is not apparently appreciated by birds 
and remains in good condition on the branches till spring. M. trans- 
itoria from western China has produced fruit in the Arboretum this 
year for the second time. It is ellipsoidal in shape, rose pink, darker 
on one side than on the other, very lustrous and about three-quarters 
of an inch long. The fruit of few Crabapples is more distinct and 
beautiful. Only a few plants in the Collection are mentioned in this 
Bulletin. Many others are equally interesting, and a study of the 
group will show possibilities for garden decoration which few persons 
in this country realize. In planting Crabapples it is well to remember 
that they only really thrive in rich, well-drained soil, that they require 
plenty of room in which to display their greatest beauty, that they 
are often attacked by the San Jose Scale which is easily controlled by 
spraying, and that their leaves are preyed on by the caterpillars which 
feed on the leaves of the Apple-trees of orchards. 
Autumn Flowers. A few flowers can still be seen in the Arboretum, 
although the number of trees and shrubs which bloom in Massachusetts 
during the first weeks of October is not large. Aralia spinosay 
the Hercules’ Club of the middle and southern states, is still covered 
with its great terminal clusters of white flowers. These great flower- 
clusters and its compound leaves three or four feet in length give this 
tree an unusual and tropical appearance in northern woods. This 
Aralia is now well established in the Arboretum at the northern base 
of Hemlock Hill in the rear of the Laurels where it is spreading into 
thickets. Indigofera amblyantha, discovered by Wilson in western 
China, has been often referred to in these Bulletins, but it is inter- 
esting to note that it is still covered with its small rose pink flowers
